New methods are needed to reduce dynamic blebbing which inhibits cell attachment and survival during passaging of pluripotent stem cells. We tested the hypothesis that activation of the P2X7 receptor by extracellular ATP during passaging initiates dynamic blebbing. The P2X7

Tissue-resident memory T cells (TRM) are noncirculating immune cells that contribute to the first line of local defense against reinfections. Their location at hotspots of pathogen encounter frequently exposes TRM to tissue damage. This history of danger-signal exposure is an

Long-term memory (LTM) consolidation requires the synthesis of plasticity-related proteins (PRPs). In addition, we have shown recently that LTM formation also requires the setting of a "learning tag" able to capture those PRPs. Weak training, which results only in short-term

Intracellular calcium ([Ca(2+)](i)) is the most relevant modulator of parathyroid hormone (PTH) secretion. Uniquely, an increase in [Ca(2+)](i) results in an inhibition of PTH secretion, and it probably exerts its function via calcium-binding protein pathways. The ubiquitous calcium-binding proteins, calmodulin
