Pneumococcal Surface Protein A Inhibits Complement Activation by Streptococcus pneumoniae
Explore this paper's citation graph
Summary
It is proposed that PspA exerts its virulence function by interfering with deposition of C3b onto pneumococci and/or by inhibiting formation of a fully functional alternative pathway C3 convertase by blocking recruitment of the alternative pathway.
