Toll-like receptors (TLRs) play a fundamental role in the immune system by detecting pathogen associated molecular patterns (PAMPs) to sense host infection. Ethanol at doses relevant for humans inhibits the pathogen induced cytokine response mediated through TLRs. The current study was designed to investigate the mechanisms of this effect by determining whether ethanol inhibits TLR3 and TLR4 mediated TNF-? secretion through inhibition of transcription factor activation or post-transcriptional effects. In NF-?B reporter mice, activation of NF-?B in vivo by LPS was inhibited by ethanol (LPS alone yielded 170,000?35,300 arbitrary units of light emission; LPS plus ethanol yielded 56,120?16880, p = …
