response, is able to opsonize pathogen before adaptive immunity may even be required. Complement proteins involved in innate opsonization include C4b, C3b...

eosinophils are sometimes implicated. During this process, the pathogen is opsonized and bound with the antibody IgG via its Fab domain. Cells with cyotoxic...

I FcγRs activation begins a cascade of reactions to eliminate the IgG-opsonized target. Type I FcγRs is another type of IgG constant region receptor,...

circumstances but after splenectomy, when infecting bacteria cannot be adequately opsonized, the infection becomes more severe.[citation needed] Splenectomy also...

mediates different physiological effects of antibodies (detection of opsonized particles; cell lysis; degranulation of mast cells, basophils, and eosinophils;...

antigen processing and capture provide a protected environment in which opsonized antigens can be displayed for a long time without being proteolyzed or...

molecules marks the microbe for ingestion by phagocytes in a process called opsonization; these phagocytes are attracted by certain complement molecules generated...

Post-splenectomy: A major function of the spleen is the clearance of opsonized, deformed, and damaged erythrocytes by splenic macrophages. If splenic...

infections. The alternative pathway is one of three complement pathways that opsonize and kill pathogens. The pathway is triggered when the C3b protein directly...

peptides that attract immune cells, increase vascular permeability, and opsonize (coat) the surface of a pathogen, marking it for destruction. This deposition...

together via agglutination; IgG coating of pathogen surfaces (known as opsonization) allows their recognition and ingestion by phagocytic immune cells leading...

when activated, creates a cascade of chemical reactions that promotes opsonization, chemotaxis, and agglutination, and produces the MAC. The kinin system...

antibodies lower infection through three main pathways: neutralization, opsonization, and complement activation. Antibodies neutralize pathogens by binding...

recognized, they must be coated in opsonins – a process known as antibody opsonization. They can internalize and kill many microbes, each phagocytic event resulting...

up larger particles. They utilize activated CR3s to ingest complement-opsonized targets. Non-osteoclast MGCs are also responsible for the clearance of...

These proteins can bind to sugars on the surface of pathogens and thereby opsonize them for uptake by phagocytes. It also regulates inflammatory responses...

proliferation of cytotoxic CD8+ T cells. Also promotes the production of IgG, an opsonizing antibody. Humoral immune system. Stimulates B-cells into proliferation...

replicating virus or invading bacterium. Virus or bacteria with antibodies opsonized or "stuck" to them highlight them to other cells of the immune system...

negative regulation of macrophage derived foam cell differentiation opsonization defense response to Gram-positive bacterium complement activation, classical...

activity. Both complement proteins and antibodies can bind to antigens and opsonize them. Macrophages have complement receptor 1 (CR1) and 3 (CR3) that recognize...
