The transmembrane protein LAT (linker for activation of
T cells) couples the T cell receptor (TCR) to downstream
signalingeffectors. Mice homozygous for a mutation of a single LAT
tyrosineresidue showed impeded T cell development. However, later theyaccumulated polyclonal helper T (TH) cells that
chronically producedtype 2 cytokines in large amounts. This
exaggerated TH2 differentiationcaused tissue eosinophilia
and massive maturation of plasma cellssecreting to immunoglobulins of
the E and G1 isotypes. This paradoxicalphenotype establishes an
unanticipated inhibitory function forLAT that is critical for the
differentiation and homeostasis ofTH cells.
