TLR4 interactor with leucine-rich repeats (TRIL) is a brain-enriched accessory protein important in Toll-like receptor 3 and 4 signalling. Here we generated TRIL-deficient mice and examined TLR responses in vitro and in vivo. We found a role for TRIL in both TLR4 and TLR3 signalling in mixed glial cells, consistent with the high level of expression of TRIL in these cells. We also found that TRIL is a modulator of the innate immune response to LPS challenge and E.coli infection in vivo. TRIL-deficient mice produce lower levels of multiple proinflammatory cytokines and chemokines specifically within the brain following E.coli and LPS challenge. Collectively these data uncover TRIL as a mediator of innate immune responses within the brain, where it enhances neuronal cytokine responses to infection.
