Immunsejteknek

Immunsejteknek is a Hungarian term that translates to "immune cells" in English. These are the cells that make up the immune system, a complex network of cells, tissues, and organs that work together to defend the body against pathogens, such as bacteria, viruses, and fungi, as well as abnormal cells, like cancer cells.

The immune system relies on a diverse population of specialized immune cells, each with distinct roles. Key types include lymphocytes, such as B cells, T cells, and natural killer (NK) cells. B cells are responsible for producing antibodies, proteins that target and neutralize specific invaders. T cells have various functions, including directly killing infected cells (cytotoxic T cells) or helping to regulate the immune response (helper T cells). NK cells are important for rapidly responding to virally infected cells and tumor cells.

Other crucial immune cells include phagocytes, such as macrophages and neutrophils. These cells engulf and digest pathogens and cellular debris through a process called phagocytosis. Dendritic cells act as messengers, presenting pieces of pathogens to T cells to initiate a targeted immune response. Mast cells are involved in allergic reactions and defense against parasites.

The coordinated action of these immunsejteknek is essential for maintaining health. When they function correctly, they can identify and eliminate threats before they cause significant harm. However, malfunctions in these cells can lead to immunodeficiency disorders, autoimmune diseases, or cancer. Understanding the roles and interactions of immunsejteknek is fundamental to immunology and the development of treatments for a wide range of diseases.
