How to use

In Vitro:

TLR1 inhibits IL-1β-induced phosphorylation of the mitogen-activated protein kinase p38 in EL4 thymoma cells and in freshly isolated murine lymphocytes in a concentration-dependent manner.

In Vivo:

TLR1 interferes with the interactions between mouse MyD88 and IL-1RI at the TIR domains. TLR1 produces a significant attenuation of the IL-1β-induced fever response (200 mg/kg, i.p.)
