Allergic airway inflammation is driven by type-2 CD4+ T cell inflammatory responses. We uncover an immunoregulatory role for the nucleotide release channel, Panx1, in T cell crosstalk during airway disease. Inverse correlations between Panx1 and asthmatics, and our mouse models revealed the necessity, specificity, and sufficiency of Panx1 in T cells to restrict inflammation. Global Panx1−/− mice experienced exacerbated airway inflammation, and T cell-specific deletion phenocopied Panx1−/− mice. A transgenic designed to re-express Panx1 in T cells reversed disease severity in global Panx1−/− mice. Panx1 activation occurred in pro-inflammatory Teff and inhibitory Treg cells and mediated the extracellular nucleotide based Treg-Teff crosstalk required for suppression of Teff cell proliferation. Mechanistic studies identified a Salt inducible kinase-dependent phosphorylation of Panx1 serine 205 important for channel activation. A genetically targeted mouse expressing non-phosphorylatable Panx1S205A phenocopied the exacerbated inflammation in Panx1−/− mice. These data identify Panx1-dependent Treg:Teff cell communication in restricting airway disease. While extracellular nucleotides (ATP) are known to be important, the source and regulation of ATP at immune microenvironments is still unclear. Medina et. al. show that CD4+ Teff and CD4+ Treg cells use a SIK-Panx1 axis to control nucleotide release for inter-T cell communication and suppression of allergic airway inflammation.
