Hjelpeceller

Hjelpeceller, also known as helper cells, are a type of white blood cell that play a crucial role in the immune system's response to infection and disease. They are categorized into two main types: cytotoxic T cells and helper T cells. Cytotoxic T cells directly attack and destroy infected cells, while helper T cells coordinate the immune response by communicating with other immune cells. Helper T cells are further divided into subsets based on the cytokines they produce, such as Th1, Th2, Th17, and Treg cells. Each subset plays a specific role in the immune response, with Th1 cells enhancing cell-mediated immunity, Th2 cells promoting humoral immunity, Th17 cells involved in inflammation, and Treg cells regulating immune responses to prevent autoimmune diseases. Hjelpeceller are essential for maintaining immune homeostasis and protecting the body from pathogens. Their dysfunction or dysregulation can lead to various immune-related disorders, including autoimmune diseases and certain cancers. Understanding the role and regulation of helper cells is vital for developing effective treatments for these conditions.
