demonstrated that mice with cDC2‐specific migration defect due to the deletion of Dock8 in CD11c+ cells show reduced Tfh cell development following subcutaneous or intranasal immunization with OVA and LPS or with nanoparticle‐formulated vaccine adjuvant PLGA, as well as diminished production of antiviral IgG upon intranasal infection with influenza virus [50]. The gene discussed is ITGAX; the disease is infection.
