Abstract
Mice carrying the recessive locus for peripheral T cell deficiency (Ptcd) have a block in thymic egress, but the mechanism responsible is undefined. Here we found that Ptcd T cells had an intrinsic migration defect, impaired lymphoid tissue trafficking and irregularly shaped protrusions. Characterization of the Ptcd locus showed a point substitution of lysine for glutamic acid at position 26 in the actin regulator coronin 1A that enhanced its inhibition of the actin regulator Arp2/3 and resulted in its mislocalization from the leading edge of migrating T cells. The discovery of another coronin 1A mutant during an N-ethyl-N-nitrosourea-mutagenesis screen for T cell–lymphopenic mice prompted us to evaluate a T cell–deficient, B cell–sufficient and natural killer cell–sufficient patient with severe combined immunodeficiency, whom we found had mutations in both CORO1A alleles. Our findings establish a function for coronin 1A in T cell egress, identify a surface of coronin involved in Arp2/3 regulation and demonstrate that actin regulation is a biological process defective in human and mouse severe combined immunodeficiency.
