Ficolins do not alter host immune responses to lipopolysaccharide-induced inflammation in vivo

Abstract Ficolins are a family of pattern recognition molecules that are capable of activating the lectin pathway of complement. A limited number of reports have demonstrated a protective role of ficolins in animal models of infection. In addition, an immune modulatory role of ficolins has been sugg...
