XCR1 and allergic asthma: Our recent study13 on the role of iNKT cells in murine allergic asthma models induced by ovalbumin (OVA) and house-dust mite (HDM) suggests that iNKT cells also promote the development of allergic asthma by enhancing the migration of XCR1-expressing type-1 conventional DCs (cDC1s) into asthmatic lungs.
