Immunological disturbances such as persistent activation of immune cells and reduced cytotoxicity by natural killer (NK) cells are reported as key aspects in post‐COVID‐19 condition (PCC). Our findings provide new evidence of altered passive and TRPM3‐mediated Ca2+ influx, significantly impacting cytoplasmic and mitochondrial Ca2+ mobilization in PCC ...

Functional Role of Piezo1 in Regulating Whole‐Lung Vascular Reactivity
ABSTRACT Mechanosensitive cation channels expressed in pulmonary arterial smooth muscle (SMC) and endothelial (EC) cells contribute to the regulation of vasoconstriction and vasodilation of the pulmonary vasculature. Here, we report that activating Piezo1, a mechanosensitive cation channel, with Yoda1 induced a mild increase in pulmonary arterial ...

cAMP Induces Stromal Interaction Molecule 1 (STIM1) Puncta but neither Orai1 Protein Clustering nor Store-operated Ca2+ Entry (SOCE) in Islet Cells [PDF]
The events leading to the activation of store-operated Ca(2+) entry (SOCE) involve Ca(2+) depletion of the endoplasmic reticulum (ER) resulting in translocation of the transmembrane Ca(2+) sensor protein, stromal interaction molecule 1 (STIM1), to the junctions between ER and the plasma membrane where it binds to the Ca(2+) channel protein Orai1 to ...

Orai1 mediates exacerbated Ca(2+) entry in dystrophic skeletal muscle. [PDF]
There is substantial evidence indicating that disruption of Ca(2+) homeostasis and activation of cytosolic proteases play a key role in the pathogenesis and progression of Duchenne Muscular Dystrophy (DMD).

CD95 triggers Orai1-mediated localized Ca 2+ entry, regulates recruitment of protein kinase C (PKC) β2, and prevents death-inducing signaling complex formation [PDF]
The death receptor CD95 plays a pivotal role in immune surveillance and immune tolerance. Binding of CD95L to CD95 leads to recruitment of the adaptor protein Fas-associated death domain protein (FADD), which in turn aggregates caspase-8 and caspase-10.

Hsp90 Breaks the Deadlock of the Hsp70 Chaperone System [PDF]
Protein folding in the cell requires ATP-driven chaperone machines such as the conserved Hsp70 and Hsp90. It is enigmatic how these machines fold proteins.
