TLR2 and infection: In addition, the recombinant LRR38 encoded by LSS_01692 interacted with fibronectin, collagen IV, and Toll-like receptor 2 (TLR2); furthermore, rLRR38 induced inflammation involving the NF-κB and MAPK signal transduction pathways, suggesting its participation during infection (Hsu et al., 2021).
