ITGAM and allergic disease: A recent study reported that IFN‐I could induce the CD64midMAR‐1+CD11b+ cDC2 subset, known as inf‐cDC2, which acquires characteristics typically defining cDC1 and macrophages during respiratory viral infection and allergy.[28] Therefore we investigated whether IFN‐I could also induce a similar CD11b+ DC subset during ME49Δompdc/gra4 immunization.
