TLR3 specifically recognizes
Explanation
TLR3 is an endosomal receptor that recognizes double-stranded RNA, a molecular signature of many viral infections. Signaling proceeds exclusively through the adaptor TRIF, leading to activation of IRF3 and production of type-I interferons. This pathway is critical for antiviral innate immunity in both immune and non-immune cells. Careful
