MAIT and iNKT cells have similar developmental dynamics and thymic-residency properties but proliferate at different developmental stages.MAIT cells exit the thymus in an S1PR-dependent manner at different maturation stages to colonize specific peripheral organs.PLZF+Tbet-RORgt- MAIT cells preferentially colonize the intestine in a CCR9-dependent manner.Thymic output contributes to peripheral MAIT and iNKT cell numbers at steady state. Thymic MAIT17 cells are activated and expand in colitis and after bacterial exposure.</description><dates><publication>2026/04/13</publication></dates><accession>GSE308509</accession><cross_references><GSM>GSM9247074</GSM><GSM>GSM9247075</GSM><GSM>GSM9247076</GSM><GSM>GSM9247077</GSM><GSM>GSM9247073</GSM><GPL>24247</GPL><GPL>16417</GPL><GSE>308509</GSE><taxon>Mus musculus</taxon></cross_references></HashMap>
