05) in the first 2.5 s after stimulus presentation PD0325901 cell line depending on the condition. Figure 1A displays the difference for the first 2.5 s following the presentation of the stimulus. Average ΔPSTH for each tastant follows a similar trend (inset in Figure 1A). The largest difference between responses occurred early; ∼250 ms after stimulus delivery, the difference decayed to 50% of its maximum (see dotted box in Figure 1A). Firing rates in the first 250 ms significantly differed for 31.2% (93 of 298) of GC neurons (p < 0.05). No clear trend toward an increase or decrease of firing rates was observed for either condition; the proportion of neurons firing more to UT or to ExpT

was similar (see Figure S1, available online, for a complete analysis). To determine

the influence of early changes in firing rates on taste coding, the initial 250 ms was divided in two 125 ms bins. Single neurons were defined as taste responsive in a certain bin if their firing rates in response to the four tastants differed significantly according to a one-way ANOVA Fluorouracil mouse (p < 0.05). As shown in Figure 1B, the percentage of taste-coding neurons was higher for self-deliveries in the first two bins, with the maximal increase, 52.4%, in the first 125 ms (from 7.0%, 21 of 298, for UT to 10.7%, 32 of 298, for ExpT) and a 37.8% increase in the 125–250 ms interval (from 12.4%, 37 of 298, for UT to 17.1%, 51 of 298, for ExpT). The neurons coding for ExpT were among those being affected by expectation as demonstrated by their ΔPSTH. In those neurons the difference in the first two bins was significantly larger than background values (first 125 ms bin: 7.4 ± 1.1 Hz versus 2.5 ± 0.4 Hz, n = 32, p < 0.01; second 125 ms bin: 7.1 ± 0.9 versus 3.1 ± 0.4, n = 51, p < 0.01) and larger than the ΔPSTH observed for the other neurons (first 125 ms bin: 3.0 ± 0.3 Hz, n = 266, p < 0.01; second 125 ms bin: 2.5 ± 0.2, n = 247, p < 0.01). A classification analysis was used to establish the impact of single-cell changes on taste processing in neural ensembles. This analysis made it possible to determine

whether ensemble firing patterns in the early portion of responses to ExpT (0–125 and 125–250 ms) allowed better stimulus discrimination than responses to UT. Figure 1C shows the result of a population PSTH-based classification algorithm averaged http://www.selleck.co.jp/products/MDV3100.html over all of the experimental sessions; a significant difference in favor of ExpT was observed in the first 125 ms (ExpT: 33.8% ± 1.8%, UT: 27.4% ± 1.9%, p < 0.01, n = 38). Although activity evoked by UT did not allow for an above-chance performance, responses to ExpT were classified correctly in a significantly larger percentage than chance (p < 0.01). Thus, cueing enabled more accurate coding in the earliest response interval. This improvement in taste coding was restricted to the first 125 ms of the response, whereas in the interval between 125 and 250 ms, UT and ExpT trials showed a similar above-chance (p < 0.

We found that subjects repeated successful movements more frequently than find more error-based learning would predict; from a pure error-based learning perspective, such behavior is suboptimal as it competes with time that could be spent on practice to target directions

still associated with large errors – why revisit targets that you have already solved? This behavior is less surprising in our framework, which provides a possible explanation for this apparently sub-optimal behavior; namely that repeating a successful movement is a way to reinforce it. Indeed there are data from other areas of cognitive neuroscience that demonstrate that repeating something that you have successfully learned 17-AAG supplier is the best way to remember it (Chiviacowsky and Wulf, 2007, Karpicke and Roediger, 2008 and Wulf and Shea, 2002). We propose that motor skills are acquired through the combination of fast adaptive processes and slower reinforcement processes. We have shown that use-dependent

plasticity and operant reinforcement both occur along with adaptation. Based on our results, we argue that heretofore unexplained, or perhaps erroneously explained, phenomena in adaptation experiments result from the fact that most such experiments inadvertently lie somewhere between our adaptation-only protocol and our adaptation-plus-repetition protocol, with the result that three distinct forms of learning—adaptation, use-dependent plasticity, and operant reinforcement—are unintentionally lumped together. Future work will need

to further dissect these processes and formally model them. The existence of separate learning processes may indicate an underlying anatomical separation. Error-based learning is likely to be cerebellar dependent (Martin et al., 1996a, Martin et al., 1996b, Smith and Shadmehr, 2005 and Tseng et al., 2007). Use-dependent learning may occur through Hebbian changes in motor cortex (Orban de Xivry et al., 2011; Verstynen and Sabes, 2011). The presence of dopamine receptors on cells in primary motor cortex (Huntley et al., 1992, Luft and Schwarz, 2009 and Ziemann et al., 1997) could provide a candidate mechanism Teicoplanin for reward-based modulation of such use-dependent plasticity (Hosp et al., 2011). Our suggestion of an interplay between a model-based process in the cerebellum and a model-free retention process in primary motor cortex is supported by the results of a recent non-invasive brain stimulation study of rotation adaptation; adaptation was accelerated by stimulation of the cerebellum, while stimulation of primary motor cortex led to longer retention (Galea et al., 2010). Finally, operant reinforcement may require dopaminergic projections to the striatum (Wächter et al., 2010).

Since T cell responses were only detected against NS1 and NS2 (BTV-2), but not VP2 (BTV-8), the observed lymphocyte proliferation to UV-inactivated BTV-8 in vitro suggests cross-serotype reactions induced by the NS proteins, although responses induced by VP2, but not detected in peripheral circulation by the VP2-specific assay employed herein, cannot be excluded. Furthermore, Modulators species differences in T cell responses to the same protein, such as VP2-specific lymphoproliferation observed following

vaccination in mice but not cattle [24], highlights the importance of performing vaccine studies in Selleckchem Bioactive Compound Library the target species. Specific T cell responses from samples collected on PID7 could not be determined because of poor viability, likely due to storage of this batch of cells in liquid nitrogen (data not shown). Taken together, the vaccine-induced protection was probably due to serotype-specific neutralizing

antibodies against VP2 and cross-serotype immune responses to NS1 and NS2. Even though the roles of NS1 and NS2 in protection need further investigation, we believe that the diverse immune responses induced by the mixture of BTV proteins included in SubV may contribute selleck chemicals to its efficacy against different BTV-8 strains and perhaps to a long duration of immunity, by potentially stimulating a broader pool of memory B and T cells and long-lived plasma cells. This would have to be investigated since it has direct consequences

on vaccine use in livestock such as cattle, which have a long economical life crotamiton compared to shorter-lived agricultural animals such as swine and poultry. It is notable that compared to the preceding study [26], we decreased the adjuvant quantity in SubV by 25% and observed less systemic and local reactions following vaccination, yet still observed similar immunological responses. The DIVA characteristic of SubV is based on the detection of VP2 antibodies, to prove serotype-specific infection or vaccination, and differences in VP7 antibody levels, to distinguish between infection and vaccination with any serotype. VP7 has been shown to induce good immune responses that do not seem to be essential for protection [16], [43] and [49] and therefore is a good DIVA candidate. All calves were BTV-8 seropositive within 3 weeks following BTV-8 vaccination or infection. Furthermore, following BTV-8 challenge, high VP7-specific antibody levels were rapidly detected in the sera of all controls. VP7 antibodies were also detected in vaccinated calves, but at lower levels than controls and therefore the vaccinated and unvaccinated animals could be distinguished.

To quantify IL-4 and IFNγ, fluoresceinated microbeads coated with capture antibodies (IL-4: BVD-1D11; IFN-γ:AN-18) were added to 50 μl BAL fluid and incubated overnight at 4 °C. Cytokines were detected with biotinylated anti-IFNγ (XMG1.2) and -IL-4 (BVD6-24G2), and PE-labeled streptavidin. Fluorescence was measured using a Luminex model 100 XYP (Luminex, Austin, TX, USA). Antibodies were purchased from BD

Biosciences. Naïve and PVM-infected (d. 14 p.i.) donor mice were sacrificed, single cell suspensions prepared of lungs, spleens and MLNs were mixed and stained Erlotinib with PE-labeled antibodies against CD19, CD4, MHC-II and NKp46 (without Fc-block). Negative selection was performed using a BD Influx (BD check details Biosciences). Recipient mice received 5 × 106 enriched cells in 200 μl PBS i.v., and then were infected with PVM. Intranasal infection with 25 pfu of PVM strain J3666 induced severe but sublethal disease in BALB/c mice, with weight reduction of approximately 15–20% of original body weight (data not shown). During the first days of infection, PVM rapidly replicated to high numbers (Fig. 1A). Viral copy numbers peaked at d. 8 p.i. and then declined. In order to determine their inhibitors protective capacity, we first studied CD8+ T-cell kinetics during primary PVM infection and compared these with the well-described CD8+ T-cell responses in influenza and hRSV-infected mice [36] and [37]. The relative proportions of CD8+ T-cells in the

airways of PVM-infected mice strongly increased over time (Fig. 1B), and from d. 10 onwards approximately

60% of lymphocytes in the BAL were CD8+ T-cells. In influenza- and hRSV-infected mice, initially, the proportions of CD8+ T-cells in the airways were higher than in PVM-infected mice but then dropped, when relative proportions of CD8+ T-cells in PVM-infected mice were still rising (Fig. 1B). Quantification of virus-specific CD8+ T-cells with MHC class I tetramers containing a dominant epitope of either PVM (P261–269[30]), influenza (NP147–155[38]) or hRSV (M282–90[39]), demonstrated that NP147–155- and M282–90-specific CD8+ T-cells Ergoloid were detectable at d. 6 p.i. and expanded until d. 8–10 p.i. when a plateau was reached (Fig. 1C). In PVM-infected mice, the BAL did not contain any P261–269-specific CD8+ T-cells at d. 6 p.i, and only a small population of P261–269-specific CD8+ T-cells could be detected at d. 8 p.i. (Fig. 1D and E). The relative proportions of P261–269 tetramer+ CD8+ T-cells further increased until d. 10 p.i. after which levels remained high (Fig. 1D and E). To determine whether PVM-specific CD8+ T-cell were functional, we quantified IFNγ production in virus-specific CD8+ T-cells after ex vivo P261–269 stimulation. Consistent with earlier publications [30] and [37], we found that IFNγ producing P261–269-specific CD8+ T-cells were barely detectable at d. 8 of infection ( Fig. 1F and G) but then increased in numbers.

Labor progresses rapidly (see Fig. 1) and 25 min after arrival at the hospital she fells an initial urge to push. Another 10 min later the water breaks; it is meconium-stained,

and the cervix is now dilated to 9 cm. The fetal head is now 1 cm above the ischial spines. CTG is applied again and due to the patient record it reveals minor FHR decelerations that return to normal baseline. She receives an oxygen mask. At 1.05 am the midwife encourages GDC-0199 chemical structure her to push. The head is described as just below the spines. The descent of the head of the baby progresses normally during pushes, but it retracts between contractions. After 20 min of pushing there is still no sign of further fetal decent and the woman is asked to gasp. Due to the lack of progression an obstetrician is called and arrives at 1.35 am. The fetal head is still just below the spines. The obstetrician orders

Syntocinon® (generic name oxytocin) 10 I.E. in a 1000 ml NaCl-solution. Due to the already frequent contractions the drip is started cautiously 6 ml/h that is half the standard dose. At 1.50 am the woman is again encouraged to push. It is noted in the hospital record that ‘the drip is slowly increased to 24 ml/h’. Suddenly at 2.06 am there Crizotinib is fetal bradycardia to 75–80 beats per minute and the fetal head inhibitors detracts resulting in a loss of fetal station. Simultaneously the woman starts to complain about unremitting abdominal pain and she turns pail. As the uterus

is palpated uterine defense is noted and an emergent cesarean section is ordered. A girl is born 14 min later, Apgar 1/1, 5/10 min and pH 6.68, SBE − 19 and weight 4800 g. The baby is transferred to an intensive care unit in another hospital. She receives 72 h of hypothermal treatment. At age 3 the girl is diagnosed with cerebral palsy. The uterus is severely damaged. There is a full, posterior rupture extending from the fundus down, and there is almost a complete separation between the uterus and the vagina. The uterine scar is sewed continuously but with numerous insertions due to uncontrollable bleeding. The uterus is restored, but she bleeds 5500 ml during the operation. Two hours after the termination of the operation she is bleeding heavily again, and Urease is re-operated. The bleeding is located at the lower part of the uterine rare side and in the left side of cervix and after several insertions hemostasis is obtained. However there is still diffuse bleeding from the fundal part. A double B-lynch suture is applied. In the patient record it is estimated that the total blood loss was 10 l. She receives 27 product with 245 ml erythrocytes, 18 product with 270 ml plasma and 9 products with 350 ml thrombocytes. She also received approximately 2.4 l NaCl solution which indicates that her blood loss might have been underestimated (total amount of IV products = 14.6 l + 2.4 l NaCl). After the second operation she is sedated for approximately 14 h.

7 Vincristine sulphate was used as positive control. The AZD2281 cost thrombolytic activity was evaluated by the method developed by Prasad et al (2006)8 by using streptokinase (SK) as positive control. The membrane stabilizing activity of the extractives was assessed by evaluating their ability to inhibit hypotonic inhibitors solution and heat induced haemolysis of human erythrocytes following the method developed by Omale et al (2008).9 Antimicrobial activity was determined by disc diffusion method.10 For all bioassays, three replicates of each sample were used for statistical analysis and the values are reported as mean ± SD. The present study was undertaken to evaluate the antioxidant potential in

terms of total phenolic content, phosphomolybdenum total antioxidant capacity and free radical scavenging property; cytotoxic, thrombolytic, membrane stabilizing and antimicrobial activities of different Pictilisib nmr organic and aqueous soluble materials of the crude methanol extract of A. blanchetii. In DPPH free radical scavenging assay, different extractives of A. blanchetii demonstrated free radical scavenging potential with IC50 values ranging from 40.50 to 119.21 μg/ml. The highest free radical scavenging activity was demonstrated by the carbon tetrachloride soluble fraction (IC50 = 40.50 ± 0.32 μg/ml) which could be correlated to its phenolic content 21.08 ± 0.41 mg

of GAE/g of extractives. A positive correlation was seen between total phenolic content and total antioxidant activity of A. blanchetii ( Table 1). In case of brine shrimp lethality bioassay, all the fractions demonstrated significant cytotoxic potential against A. salina with LC50 values ranging from 0.78 to 92.82 μg/ml. The hexane soluble fraction revealed the highest cytotoxic activity with LC50 value 0.78 ± 0.74 μg/ml as compared to 0.45 μg/ml

for Vincristine sulphate ( Table 1). The extractives of A. blanchetii demonstrated mild to moderate thrombolytic activity. The chloroform soluble fraction showed 32.50 ± 0.63% of clot lysis as compared to 66.77% clot lysis by standard streptokinase ( Table 2). At concentration 1.0 mg/ml, the extractives of A. blanchetii protected the haemolysis of RBCs induced by hypotonic solution and heat as compared to the standard acetyl salicylic acid (0.10 mg/ml). The Astemizole chloroform soluble fraction inhibited 46.74 ± 0.73% and 41.33 ± 0.59% of haemolysis of RBCs induced by hypotonic solution and heat as compared to 71.90% and 42.12% by acetyl salicylic acid, respectively ( Table 3). The antimicrobial activity of A. blanchetii test samples was evaluated against 5 gram positive and 8 gram negative bacteria and three fungi and the results were compared with standard antibiotic, ciprofloxacin. The test samples of A. blanchetii revealed antimicrobial activity with zone of inhibition ranging from 7.0 to 13.0 mm. The highest zone of inhibition (13.

, 1994). In both vertebrates and invertebrates, a transcription factor, CREB, plays a critical role in gene

expression required for LTM formation ( Bourtchuladze et al., 1994 and Yin et al., 1994). While previous SB431542 order studies have shown that hypomorphic mutations in Drosophila NMDARs (dNMDARs) disrupt both associative learning (LRN) and LTM formation without affecting ARM ( Wu et al., 2007 and Xia et al., 2005), it is still not clear how Mg2+ block is involved in these processes. To understand the functional significance of Mg2+ block in dNMDARs, we generated transgenic flies expressing dNR1 mutated at the Mg2+ block site, dNR1(N631Q), in neurons. Strikingly, we found that these Mg2+ block mutant flies are defective for LTM formation but not LRN. We show that Mg2+ block functions to suppress basal

expression of a repressor isoform of Drosophila CREB during uncorrelated activity. This allows increased CREB-dependent gene expression to occur during correlated activity, leading to formation of LTM. Immunohistochemical studies using antibodies to dNR1 demonstrate that dNMDARs are expressed throughout the Drosophila brain ( Figure S1 available online) ( Xia et al., 2005, Zachepilo et al., 2008 and Zannat et al., 2006). Therefore, we used an elav-GAL4/UAS-GFP (elav/GFP) transgenic line ( Brand and Perrimon, 1993), which expresses GFP in

neurons, selleck chemicals to characterize endogenous dNMDARs in pupal primary cultured neurons ( Figure 1A). Using whole-cell patch clamp, we determined that more than 85% of GFP-positive cells showed NMDA-induced inward currents at a −80mV membrane potential in the absence of external Mg2+ (119 out of 136 cells, Figure 1B). These responses were blocked by physiological concentrations of 20 mM Mg2+ ( Stewart et al., because 1994). In addition, mammalian NMDAR antagonists, APV and MK801, significantly suppressed NMDA-activated currents ( Figure 1C). These results demonstrate that endogenous dNMDARs are widely expressed in neurons of the fly brain and have similar physiological and pharmacological properties to mammalian NMDARs. We overexpressed either wild-type dNR1(wt) or Mg2+-block-site-mutated dNR1(N631Q) transgenes ( Figure 2A) in neurons using an elav-GAL4 driver: elav-GAL4/UAS-dNR1(wt), [elav/dNR1(wt)], and elav-GAL4/UAS-dNR1(N631Q), [elav/dNR1(N631Q)]. Overexpression of dNR1(wt) and dNR1(N631Q) proteins was confirmed by western blots ( Figure S2). As seen in  Figure 2B, all dNMDAR-mediated currents in neurons from elav/dNR1(wt) pupae showed significant Mg2+ block in the presence of Mg2+, a result similar to what was seen in neurons from wild-type pupae.

05 versus control; Figures 7C and 7D). In the presence of the V1a antagonist, however, U-50488 failed to affect the firing activity of presympathetic neurons (p > 0.6, n = 4; Figure S7B), Pazopanib supplier arguing against a direct effect of U50488 on the latter. No correlation between basal PVN-RVLM firing activity and the magnitude of the V1a antagonist effect was found in any of these different conditions (Pearson r = −0.02; p > 0.5). Dialysis of BAPTA into the recorded PVN-RVLM neurons prevented the effects of the V1a antagonist (baseline, 0.7 ±

0.1 Hz; V1a antagonist, 0.6 ± 0.1 Hz; p > 0.3, n = 6). A diffusible signal in the ECS could be influenced both by its half-life and the ECS tortuosity. Blockade of tissue aminopeptidase activity (amastatin

10 μM) increased the firing activity of presympathetic neurons (p < 0.01, n = 8; Figure 7E). The amastatin effect was not only blocked but also actually turned into an inhibitory effect in the presence of the V1a receptor blocker (p < 0.01 versus amastatin control, n = 7; Figure 7E). These results indicate that aminopeptidase blockade increased not only the availability and excitatory actions of endogenous VP but also of an unknown inhibitory signal, which was only unmasked when the VP excitatory effect was blocked. The identity of this inhibitory peptide signal was not further JAK inhibitor investigated in this study. Reducing the coefficient of diffusion in the ECS with 5% dextran (40 kDa)

(Min et al., 1998 and Piet to et al., 2004) also blocked the V1a antagonist effect on presympathetic firing discharge (−6.5% ± 8.8%; p > 0.6, n = 4). Taken together, these results indicate that tonically released VP within the PVN serves as a neurosecretory population signal, which acting in a diffusible manner, increased the activity of the presympathetic PVN neuronal population. We finally assessed whether dendritic release of VP serves as an interpopulation signal by which the integrated sympathoexcitatory output from the entire presympathetic neuronal population was modulated. To this end, we performed in vivo studies to directly monitor sympathoexcitatory outflow from the PVN. We found that direct microinjection of VP (8–32 pmol) onto the PVN elicited a dose-dependent sympathoexcitatory response, reflected by an increase in renal sympathetic nerve activity (RSNA; p < 0.02, n = 9; Figures 8A and 8B). These results indicate that the VP excitatory effect observed on presympathetic neurons in vitro translated into a systemic, population sympathoexcitatory response. It is well documented that a central osmotic challenge results in a robust PVN homeostatic response that involves an orchestrated activation of VP MNNs and presympathetic neurons, leading to increased plasma VP levels along with a concomitant increase in sympathetic outflow, respectively (Bourque, 2008 and Toney and Stocker, 2010).

Matrices were mean subtracted before performing the SVD. A matrix was classified as separable if the first singular value was significantly large (p < 0.05) when compared with the first singular value obtained after randomization of the matrix elements. Otherwise, the matrix was deemed inseparable. It has been shown previously that

this method is sufficiently sensitive to detect gain fields with as few as three trials per condition (Pesaran et al., 2010). It is important to note that the gradient analysis and SVD were used in conjunction with one another rather than separately. The gradient analysis indicates the extent to which the firing rate of the cell depends on changes in H or T; however, for cells in which both H and T influence the firing rate, this Buparlisib clinical trial analysis cannot distinguish between gain field and vector encoding (see Figures 2B and

2D), and the SVD is used to provide this information. Similarly, SVD was performed only on matrices that showed significant Bcl-2 inhibitor tuning in the gradient analysis. This allowed the categorization of a matrix as inseparable to be more meaningful than it would be if SVD was performed on all cells, including those which were not tuned to either variable. To test whether individual cells aminophylline coded exclusively for the target relative to the hand (T-H), we scored each cell on three criteria for each of the three variable-pair matrices (nine criteria in total): (1) does the matrix show significant tuning; (2) is the response field appropriately oriented (−90 degrees for the TH matrix, 0 degrees for the TG and HG matrices; see Table 1; tolerance ± 60 degrees); and (3) does the response field have the appropriate SVD categorization

(inseparable for the TH matrix, separable for the TG and HG matrices; see Table 1)? If a cell scored at least 8/9 according to these criteria, then it was classed as coding purely in hand-centered coordinates. A similar classification was conducted for target-gaze and hand-gaze encoding (see Table 1 for the appropriate response field orientations and SVD categorizations). For each cell, we fit the delay-period firing rates from all 64 trial types to a parametric model based on a Gaussian tuning curve, similarly to the model used by Chang et al. (2009): Firingrate=a×exp−(x−μ)2/2σ2×(1+gHH+gGG)+b,where x=T−(wG+(1−w)H).x=T−(wG+(1−w)H). The inputs to the model were the mean delay-period firing rates (spk/s) in the 64 different conditions and the corresponding positions of the hand (H), gaze (G), and target (T) in screen-centered degrees of visual angle (degrees).

Despite

these observations and numerous theoretical considerations, however, it is difficult to directly test the importance of spike timing in behaving animals due to the lack of approaches to control spike timing. The fact that neurons depend on Nutlin-3a manufacturer synaptic transmission to propagate information encoded in spikes to downstream neurons makes it possible to gain insights into these questions by manipulating synaptic transmission. The Syt1 KD delivered by AAVs described here provided a tool to study the role of synaptic transmission triggered by isolated spikes versus bursts of spikes, especially combined with parallel TetTox experiments and may also be useful for studying other behavioral tasks or brain regions. The observation that the prefrontal TetTox expression or Syt1 KD impaired CX-5461 price the precision of recent fear memory was surprising, suggesting that, besides the hippocampus (Frankland et al., 1998 and Ruediger et al., 2011), the medial prefrontal cortex is critically involved in determining the precision of contextual memory. Overgeneralization of fear memories is critically involved in the development of anxiety disorders such as posttraumatic stress disorder

and panic disorders. In addition, patients with these disorders normally show aberrant functions in the medial prefrontal cortex (Britton et al., 2011). It will be interesting to further dissect the neuronal circuits and molecular mechanisms involved in this phenomenon, using

approaches outlined here, to determine whether overgeneralization of fear memories does indeed involve the medial prefrontal cortex. The memory function of the prefrontal cortex is consistent with its role as a high-level multimodal association region, but similar to previous studies, our data do not distinguish between a role in retrieval, Carnitine dehydrogenase storage of remote memory, or both (Rudy et al., 2005). The AAV-DJ-mediated local manipulations of gene expression provide an efficient and convenient way for functional dissection of the prefrontal cortex. Further improvements in the techniques, such as inducible and reversible manipulations (Mayford et al., 1996) in combination with in vivo imaging (Hübener and Bonhoeffer, 2010), may shed more light on these issues. Four lentiviral vectors were constructed. Control vector contains an H1 promoter followed by a U6 promoter and an ubiquitin promoter driving mCherry expression. To construct Syt1 KD vector, we cloned a short hairpin sequence containing the Syt1 sequence 5′–GAGCAAATCCAGAAAGTGCAA−3′ into the Xho1-Xba1 locus downstream of the H1 promoter of the control vector. In TetTox vector, we cloned tetanus-toxin light chain (GenBank: L19522.1) into EcoR1 locus downstream of the ubiquitin promoter of FUW vector.
