immune complexes

immune complexes

Combinations of ANTIGEN and ANTIBODY and sometimes COMPLEMENT proteins. These complexes may be deposited in the walls of small blood vessels where they react with complement, MAST CELLS, other white cells or PLATELETS to trigger local inflammation. Immune complexes are involved in long-term infections such as ENDOCARDITIS, various kinds of ARTHRITIS, allergic ALVEOLITIS (Farmer's lung, bird-fancier's lung), and a range of kidney, arterial and skin diseases.

Immune complexes

Clusters or aggregates of antigen and antibody bound together.

Both formats generally incorporate a method to separate immune complexes on a solid phase such as a magnetic bead or particle.
In case of subcutaneous administration, immune complexes may form around the injection site, which will prevent absorption of the drug into the circulation, reducing bioavailability in the target tissues (33).
A postulated mechanism for necrotizing vasculitis in hepatitis C virus infection is a deposition of circulating immune complexes in postcapillary venules.
The above mentioned factors act either independently or jointly on the immune system, triggering the production of autoreactive B lymphocytes or abnormal types of activated T lymphocytes and of antigen presenting cells, with the consequent manufacture of auto-antibodies, immune complexes and cytokines, all these elements leading to installation of inflammation and, subsequently, of specific organ lesions [13-15].

In CIES, polysaccharide antigens conjugated with CP will be rapidly depleted by binding to preexisting anti-CP antibodies and forming the immune complexes, which eventually undergo phagocytosis by phagocytes, such as microphages or dendritic cells.
In another report, soluble immune complexes were used to activate neutrophils and induce NET formation.

Cryoglobulins in chronic hepatitis C patients are cryoprecipitable immune complexes that contain IgM rheumatoid factor (IgM anti-IgG), HCV-RNA and core proteins associated with the IgG antibodies that are produced during the immune response of B-cells against HCV antigens.
