Immune function support

“Immune function support” refers broadly to any intervention or physiological process that **enhances, regulates, or maintains the normal function of the immune system**[6][1][4][5]. This includes actions that influence immune cell activation, cytokine signaling, metabolic reprogramming in immune cells, cellular proliferation, and mechanisms for fighting pathogens or self-tolerance[1][5][6]. The term is commonly used in nutrition, immunotherapy, and clinical medicine to denote effects but does not correspond to a defined molecular entity or receptor. The immune system itself comprises diverse cell types (T cells, B cells, macrophages, dendritic cells, NK cells, etc.) and soluble signaling factors (cytokines, complement proteins, antibodies) that together protect the organism from infection, clear damaged cells, and maintain tissue homeostasis[6][1][3][5][4][7].
