Staphylococcus aureus proteins Sbi and Efb recruit human plasmin to degrade complement C3 and C3b [PDF]

open access: yes, 2012
Upon host infection, the human pathogenic microbe Staphylococcus aureus (S. aureus) immediately faces innate immune reactions such as the activated complement system. Here, a novel innate immune evasion strategy of S. aureus is described.

Analysis of C3 suggests three periods of positive selection events and different evolutionary patterns between fish and mammals. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: The third complement component (C3) is a central protein of the complement system conserved from fish to mammals. It also showed distinct characteristics in different animal groups.
