immuunivälitteisiin

Immuunivälitteisiin refers to processes or conditions mediated by the immune system. The immune system is a complex network of cells, tissues, and organs that work together to defend the body against pathogens such as bacteria, viruses, and fungi. These defense mechanisms can be broadly categorized into innate and adaptive immunity. Innate immunity provides a rapid, non-specific response, while adaptive immunity offers a slower but highly specific and long-lasting protection.

Many physiological and pathological processes involve immune mediation. For example, the immune response to an infection is a classic immuunivälitteisiin process. This involves the recognition of foreign invaders, the activation of immune cells like lymphocytes and phagocytes, and the production of antibodies and cytokines to eliminate the threat. However, the immune system can also be involved in detrimental ways. Immune-mediated diseases occur when the immune system malfunctions, leading to damage to the body's own tissues. These include autoimmune diseases, where the immune system mistakenly attacks self-antigens, and hypersensitivity reactions, such as allergies, where the immune system overreacts to harmless substances. Understanding immuunivälitteisiin mechanisms is crucial for diagnosing and treating a wide range of medical conditions.
