Immunology Maintaining Immunity

Phosphoinositide 3-kinase activity regulates many cell processes across many cell types. There are three isoforms of its catalytic subunit p110, but their specificity has not been clear. Okkenhaug et al. generated a mouse that expresses an inactive form of p110 and observed compromised B and T cell immune function. The study reveals a highly selective, nonredundant role for this isoform in lymphocyte antigen receptor signaling, as well as a drug-development target.
