What is the Origin of Immune Complex?

The term is foundational to the field of immunology, combining "immune," referring to the body's defense system, with "complex," denoting a structure composed of multiple, bound parts. This essential concept was developed through the study of hypersensitivity reactions and autoimmune disorders, recognizing the crucial and often detrimental role of antibody-antigen aggregates in human disease pathology.

What is the Mechanism of Immune Complex?

Following their formation, small and efficiently processed immune complexes are typically removed from circulation by phagocytic cells that recognize the antibody portion. Pathological complexes, often due to their size, concentration, or specific charge, evade this normal clearance and become trapped in the capillary beds of organs, such as the kidneys or joints. The deposited complexes then activate the complement cascade and attract inflammatory immune cells, leading to localized tissue damage and chronic inflammatory conditions.

Immune Complex

Meaning

An immune complex is a specific molecular structure formed when an antibody binds tightly and specifically to a soluble antigen, which can be a foreign substance or a self-derived molecule. These complexes are a normal and necessary part of the immune response, facilitating the efficient clearance of foreign materials from the systemic circulation. However, when they are formed excessively or are not effectively cleared, they can deposit in sensitive tissues, triggering inflammation and contributing to the pathogenesis of various autoimmune and inflammatory diseases.
