摘要

A s the first receptors activated during host-/ipathogen interactions, Toll-like receptors (TLRs) expressed by innate immunocytes are critical for host defense. The binding of microbial products by TLRs initiates innate immune responses and primes adaptive immunity. However, the recognition of self molecules by TLRs and impaired dampening of TLR signaling also contribute to serious diseases1. Appropriate responses and self-tolerance require correct TLR compartmen-talization. In this issue of Nature Immunology, Aksoy et al. identify the p110 delta isoform of phosphatidylinositol-3-OH kinase (PI(3)K) as an important, previously unknown mediator of this process2.
