labeled with NPs or fluorophores, bothex-vivoandin-vivo, to study the behavior of immune components and track their function. Fluorophores bind physically or chemically to the membrane proteins of isolated cells, or they are introduced into the isolated cell byactive transport,endocytosis, or ...
Consequently, the resting membrane potential (−90 mV) is close to the K+ equilibrium potential. The membrane potential is not exactly equal to the −94 mV K+ equilibrium potential, because even at rest there is some permeability to Na+, which shifts the resting membrane potential slightly...
Here, we found that cholecystokinin (CCK)-labeled duodenal neuropod cells differentiate and transduce luminal stimuli from sweeteners and sugars to the vagus nerve using sweet taste receptors and sodium glucose transporters. The two stimulus types elicited distinct neural pathways: while sweetener ...
Descemet’s membrane (DM) helps maintain phenotype and function of corneal endothelial cells under physiological conditions, while little is known about the function of DM in corneal endothelial wound healing process. In the current study, we performed i

It was reported that mitochondrial respiration generated more ATP than glycolysis, whereas glycolysis provided phospholipids for cytomembrane synthesis, ribose for nucleotide synthesis, and the driving force for chromatin accessibility alterations required for cell proliferation [41, 42]. Compared to PTA ...
Notably, we found that H2O2 treatment hindered the mitochondrial activity of KGNs, as evidenced by decreased mitochondrial membrane potential (MMP), OCR and ATP levels and increased abnormal mitochondria (Fig. 1F–H and Supplementary Fig. 1H, I), indicating that H2O2 treatment had a significant in...
