Many patients with temporal lobe epilepsy display neuron loss in the dentate gyrus. One potential epileptogenic mechanism is of GABAergic interneurons and inhibitory synapses granule cells. Stereological techniques were used to estimate numbers gephyrin-positive punctae gyrus, which reduced short-term (5 days after pilocarpine-induced status epilepticus) but later rebounded beyond controls epileptic rats. electron micrographs serial sections processed for postembedding GABA-immunoreactivity....

Activation of the inositol-requiring enzyme-1 alpha (IRE1α) protein caused by endoplasmic reticulum stress results in homodimerization N-terminal luminal domains, autophosphorylation cytoplasmic kinase and conformational changes to endoribonuclease (RNase) which render them functional can lead splicing X-box binding 1 (XBP 1) mRNA. Herein, we report first crystal structures portion a human phosphorylated IRE1α dimer complex with...

Recent advances in neural stem cell (NSC) transplantation have led to an inspiring progress alleviating central nervous system (CNS) damages and restoring brain functions from diseases or injuries. One challenge of NSC is directed differentiation transplanted NSCs into desired neuronal subtypes, such as neurons, compensate the adverse impact injury; another lies lack tools noninvasively monitor dynamics after vivo. In this study, we developed a polymer nanovehicle for morphogen sustained...

E1A binding protein (p300) and CREB (CBP) are two highly homologous multidomain histone acetyltransferases. These proteins involved in many cellular processes by acting as coactivators of a large number transcription factors. Dysregulation p300/CBP has been found variety cancers other diseases, inhibition shown to decrease Myc expression. Herein, we report the identification series potent, proline-based small-molecule acetyltransferase (HAT) inhibitors using DNA-encoded library technology...

Identification of kinase, especially protein modulators through high-throughput screening (HTS) has become a common strategy for drug discovery programs in both academia and the pharmaceutical industry. There are number platform technologies that can be used measuring kinase activities. However, there is none fits all criteria terms sensitivity, ATP tolerance, robustness, throughput, cost-effectiveness. Therefore, development homogeneous robust HTS assay some targets still challenging. We...

Abstract Neuronal spiking activity is routinely recorded using genetically encoded calcium indicators (GECIs), but imaging limited in temporal resolution and does not report subthreshold voltage changes. Genetically (GEVIs) offer better sensitivity, spike detection with fast GEVIs has required specialized equipment. Here, we the ASAP4 subfamily of that brighten response to membrane depolarization, inverting fluorescence-voltage relationship previous ASAP GEVIs. Two variants, ASAP4b ASAP4e,...

Homozygous tau knockout (Mapt-/-) mice develop age-dependent dopaminergic (DA) neuronal loss in the substantia nigra (SN) and ventral tegmental area (VTA), supporting an important function of maintaining survival midbrain neurons (mDANs) during aging. However, it remains to be determined whether microtubule-associated protein regulates differentiation mDANs embryonic developmental stages. Here, we show that haploinsufficiency postnatal day 0 (P0) heterozygous (Mapt+/-) pups, but not a...
