A new study by Yang and colleagues has revealed that TNF-alpha regulates PANX1 levels through an NF-kB-dependent mechanism in human endothelial cells. PANX1 modulates Ca2+ influx contributing to IL-1beta production independent of purinergic signaling. These novel findings expand our understanding of TNF-alpha-mediated upregulation of IL-1beta with implications for responses to tissue injury and infection.
