Diacylglycerol kinase ζ deficiency in a non-CD4(+) T-cell compartment leads to increased peanut hypersensitivity

Peanut sensitization in diacylglycerol kinase zeta (DGKζ) deficient mice led to elevated peanut-IgE levels and severe anaphylaxis. DGKζ deficient CD4(+)T cells did not account for the phenotype. Future studies will determine which immune lineage caused increased food hypersensitivity.
