T and B cells
T and B cells are specialised cells called lymphocytes. B cells are produced in the bone marrow and are distributed through the body in the lymph nodes. They respond to the 'foreign' antigens of a pathogen by producing specific antibodies - they do not fight pathogens directly. Antibodies are complex proteins that are released into the blood and carried to the site of infection. When a pathogen tries to invade the body for the first time, each of its antigens activates B cells, which divide rapidly to produce a large population of cells. When the infection is over most of the newly made B cells die but some remain in the blood so the body can respond quickly next time that same pathogen invades.
T cells are in charge of cellular immunity - they neutralize a challenge by identifying and killing it. There are helper T cells and suppressor T cells. Helper T cells stimulate an immune response, whereas suppressor T cells stop it after the infection has been eradicated. When there is an imbalance in the helper and suppressor T cells immune diseases follow. In immunodeficiency diseases such as cancer, and AIDs suppressor T cells far out number helper T cells, whereas in autoimmune diseases the helper T cells far out number the suppressor T cells.
Glyconutrients dramatically increase both the number and capacity of T cells to destroy a challenge, and increase antibody production by B cells.
