Komplementtireaktio

Komplementtireaktio is a type of immunological reaction that occurs when the complement system is activated. The complement system is a group of proteins that work together to enhance the ability of antibodies to clear pathogens from the body. The complements can be activated through three different pathways: the classical pathway, the alternative pathway, and the lectin pathway.

In a Komplementtireaktio, the complement system is activated in response to a pathogen, which triggers the production of a series of inflammation mediators and enzymes. These molecules help to achieve the complement system's goal of eliminating the pathogen, either by directly killing it or by marking it for ingestion by phagocytic cells.

One of the key features of Komplementtireaktio is the release of pentraxin molecules, such as C-reactive protein and pentraxin-3, which are produced in response to inflammatory signals. These molecules play a role in the recruitment of immune cells to the site of infection and in the regulation of the inflammatory response.

The Komplementtireaktio also involves the activation of various proteases, which cleave and signal cell membranes to initiate an inflammatory response. The complement system's role in inflammation is crucial, as excessive or inappropriate activation of this system can lead to tissue damage and disease.

Overall, Komplementtireaktio is an important immunological response that helps to protect the body from infection and disease. Its dysregulation, however, can contribute to various pathological conditions, including autoimmune disorders and allergic reactions.
