This indicates Bacillota-derived molecular patterns like lipoteichoic acids, lipoproteins, and peptidoglycan are recognized by TLR2 heterodimers (TLR2/TLR1 or TLR2/TLR6), which allow the innate immune system to sense and respond to infections by these Gram-positive bacteria [26]. This evidence concerns the gene TLR2 and infection.
