TLR4 signaling – a converged immune response pathway for hemorrhagic shock and septic shock. TLR4 not only serves as a key sensor of pathogen-associated molecular patterns (PAMPs), but also is proposed recently to act as a receptor for some endogenous molecules called “alarmins”. HDACI block TLR4 signaling at multiple steps; therefore they can inhibit immune response for both hemorrhagic shock and septic shock
