Role for Toll-like receptor 2 in the immune response to Streptococcus pneumoniae infection in mouse otitis media.

abstract：:A fibronectin-binding protein (FnBP) adhesin of Staphylococcus aureus possesses three 37- or 38-amino-acid motifs (D1, D2, and D3) that can each bind fibronectin (Fn) with low affinity and that in tandem comprise D1-3, a high-affinity Fn-binding domain. To identify epitopes for the generation of adhesion-blocking anti...
