Mitochondrial Double‐Stranded RNA in Exosome Promotes Interleukin‐17 Production Through Toll‐Like Receptor 3 in Alcohol‐associated Liver Injury

Abstract

EtOH-mediated generation of mtdsRNA contributes to TLR3 activation in Kupffer cells through exosomal delivery. Consequently, increased IL-1β expression in Kupffer cells triggers IL-17A production in γδ T cells at the early stage that may accelerate IL-17A expression in CD4⁺ T cells in the later stage of ALD. Therefore, mtdsRNA and TLR3 may function as therapeutic targets in ALD.
