MBL2 and infection: Infection decreases levels of some complement lectin pathway components (mannose-binding lectin (MBL)-associated serine protease (MASPs) and ficolin 1) as well as coagulation factors such as Factor XIII subunit B (Tritten et al., 2021b), which stabilises fibrin clots and accelerates fibrinogen cross-linking (Souri et al., 2015).
