abstract：:Lipopolysaccharide binding protein (LBP) has a well-established role in LPS-induced immune responses. Here, we report that LBP also plays an essential role in the innate immune response to Gram-positive pneumococci, specifically to their major inflammatory component, pneumococcal cell wall (PCW). LBP was present in th...
