IMMUNE SYSTEM HERBS The body's immune system consists of dendritic cells, macrophages cells, natural killer cells and complement systems. Dendritic cells - function to capture and introduce antigens to CD4 cells and T lymphocyte cells to stimulate the body's immune system and destroy antigens. Dendritic cells decrease as they age. Macrophages - act as destroyers and killers of microorganisms in cells. The presence of bacteria will cause macrophages to release a number of chemicals and cytokines and stimulate T cell activation. thymus compared to during puberty. As they age, the ability to produce antibodies decreases and T cells lose the ability to recognize foreign cells in the body. Natural killer cells - these cells kill certain cells spontaneously and are involved in host defense against a variety of tumors and infections. The function of this cell does not change with age. Complement system - consisting of plasma proteins that are important in the body's natural defense. Healthy older adults have a slightly lower level of complement components compared to younger ones. The level of complications will be higher in young people if there is a germ infection but this increase does not occur in older people.
Infectious diseases - reactivation of infectious diseases such as herpes zoster in which the incidence increases 5 times between the ages of 45 and 85, resulting in the loss of the body's immune system against varicella zoster virus. Immune Response - Antigen-specific antibody production in vaccines decreases in the elderly causing the given immunity to be less effective. Cancer - due to the deficiency of the body's immune system, it is unable to recognize and eliminate cancerous cells such as chronic limpocytic leukemia (CLL). Age-related degeneration disease - this is associated with reduced functioning of the immune system. The production of auto antibodies tends to increase in chronic diseases such as hypothyroidism, diabetes mellitus, and hypopituitarism. Practice a healthy way of life through:
