ónæmisstjón

Ónæmisstjórn is an Icelandic term that translates to "immune system control" or "immune regulation" in English. It refers to the complex biological processes that govern the activity of the immune system. The immune system is a network of cells, tissues, and organs that work together to defend the body against pathogens such as bacteria, viruses, and fungi. Ónæmisstjórn ensures that the immune system responds appropriately to threats while also preventing it from attacking the body's own healthy cells, a phenomenon known as autoimmunity.

This control involves a delicate balance of activating and suppressing immune responses. When a foreign invader is detected, the immune system mounts an attack. However, once the threat is eliminated, regulatory mechanisms kick in to dampen the immune response and restore homeostasis. Failure in ónæmisstjórn can lead to various health problems, including autoimmune diseases, where the immune system mistakenly attacks the body's own tissues, and immunodeficiency disorders, where the immune system is not strong enough to fight off infections. Research into ónæmisstjórn is crucial for understanding and treating a wide range of diseases.
