Study identifies why DOCK8 deficiency drives severe food allergies

A study in the Journal of Experimental Medicine found that DOCK8 deficiency drives severe food allergies by expanding Tfh13 cells and reducing regulatory T-cells. The findings help explain why DOCK8 mutations, but not STAT3 mutations alone, consistently lead to elevated food-specific IgE and clinically significant reactions.
