Phagocytosis is the process where cells engulf and digest particles, while opsonization is the coating of these particles with antibodies to make them more recognizable for phagocytosis.
Any substance that the immune system recognizes as foreign is called a(n) ___. (a) antibody (b) antigen (c) immunoglobulin (d) opsonin (e) cytokine. What is a weak antigen? After recognizing pathogens, what is the response of the innate immune system? (ie. What action does it ...

Moreover, MBL plays an important role in pattern recognition and innate immune defense [134]. Briefly, host defense mechanisms against M. tuberculosis use MBL in many pathways: (a) MBL acts as opsonin; (b) MBL enhances both complement dependent and independent phagocytosis; (c) and MBL ...
C3b is a good opsonin. The small peptide, C3a diffuses away and acts as a chemotactic factor and an inflammatory paracrine. The generation of complement anaphylatoxins, notably C5a, activates leukocytes and induces the production of pro-inflammatory cytokines, which could be toxic or trophic ...
