Ultrapotent chemogenetics, including the chloride-permeable inhibitory PSAM 4 -GlyR receptor, were recently proposed as a powerful strategy to selectively control neuronal activity in awake, behaving animals. We aimed validate function of dopamine D1 receptor-expressing medium spiny neurons (D1-MSNs) ventral striatum. Activation with uPSEM 792 ligand enhanced rather than suppressed D1-MSNs vivo...

All living cells have a membrane which separates inside the cell from it's outside. There is a potential difference between inside and outside of the cell. This potential difference will change during an action potential. It is quite common to peruse action potentials of skeletal muscle fibers with the Hodgkin-Huxley model. Since Hodgkin and Huxley summarized some controlling currents like inwa...

Norgaard and Gram (l), studying the chlorides of the plasma, blood, and corpuscles in anemia and polycythemia, found consistently a fall in blood chloride with rising cell volume and vice versa. The concentration of chloride in the cells was approximately only half of that in the serum. The only significant variation in this series was a decrease in cell chlorides in some of the cases of pernic...

Chloride channels are known to play critical physiological roles in many cell types. Here, we describe the expression of anion channels using RNA Seq in primary cultures of human bronchial epithelial cells (hBECs). Chloride intracellular channel (CLIC) family members were the most abundant chloride channel transcripts, and CLIC1 showed the highest level of expression. In addition, we characteri...

High-purity viable cells with low mitochondria (pavement cells) and mitochondria-rich content (chloride cells) were successfully isolated from the gill epithelium of Japanese eels, using three-step Percoll gradient low-speed centrifugation. Cytochemistry (silver staining for chloride, rhodamine-123, and Mitotracker for mitochondria and actin/spectrin immunofluorescence) and scanning electron mi...

Lysosomes are responsible for protein degradation and clearance in cellular recycling centers. It has been known that the lysosomal chloride level is enriched involved intrinsic function. However, mechanism by which levels can be sensed of chloride-mediated function unknown. In this study, we verified reduced acutely induced calcium release through TRPML1 repositioning toward juxtanuclear regio...

PURPOSE To investigate cadmium chloride cytotoxicity in human lens epithelial cells as well as the mode of cell death and its mechanism. METHODS Cultured human lens epithelial cells were challenged with cadmium chloride. Morphological changes of human lens epithelial cells caused by cadmium chloride exposure were evaluated by microscope. Cell viability was evaluated by the 3-(4,5-dimethylthia...

Chloride cells were identified by Na(+)/K(+)-ATPase immunocytochemistry at the light and electron microscope levels in gills of freshwater tilapia Oreochromis mossambicus. Turnover of chloride cells was enhanced by exposing the fish to waterborne copper (3.2 micromol l(-)(1)) for 14 days, as indicated by a 38 % increase in cells expressing proliferating cell nuclear antigen (PCNA) relative to c...
