WebHypoglycemia-induced arteriole dilations were decreased by 65% (p < 0.001) in IP3R2 knockout mice, which have reduced astrocyte Ca 2+ signaling compared to wild-type. … Web20 mrt. 2024 · In astrocyte-specific inositol 1,4,5-triphosphate six receptor type 2 (IP3R2) knockout mice and IP3R2-null mutant mice, IP3R2 led to astrocyte activation through the release of intracellular Ca 2+ stores. The results suggested that astrocyte dysfunction by Ca 2+ ions is associated with ASD-like phenotypes (Wang et al., 2024).
Ca 2+ transients in astrocyte fine processes occur via Ca 2+ influx …
