Abstract
Toll-like receptor 4 (TLR4), the innate immunity receptor for bacterial endotoxins, plays a pivotal role in the induction of inflammatory responses. There is a need to develop molecules that block either activation through TLR4 or the downstream signaling pathways to inhibit the storm of inflammation typically elicited by bacterial lipopolysaccharide (LPS), which is a major cause of the high mortality associated with bacterial sepsis. The present invention provides that a single intraperitoneal injection of 15 μgfatty acid binding protein (Fh12) 1 hour before exposure to LPS suppressed significantly the expression of serum inflammatory cytokines in a model of septic shock using C57BL/6 mice. Whereas Fh12 alone did not induce cytokine expression, it significantly suppressed the expression of IL12, TNFα, IL6 and IL1β cytokines as well as iNOS2 in bmMΦs, and also impaired the phagocytic capacity of bmMΦs. One mechanism used by Fh12 to exert its anti-inflammatory effect is binding to the CD14 co-receptor. Moreover, it suppresses phosphorylation of ERK, p38 and JNK.
