Immune system and Selenium - boost your immune system
Selenium and the immune system.
The environment that we live in, is a universe filled with all sorts of micro particles and organisms (Bacteria , Viruses, Fungi, Pollens, microscopic animals, organic and inorganic substances) which are lethal to the human being.
“How does the human body survive in this deadly environment?”
The body protects itself, by its ability to recognize it self and to reject, neutralize and destroy, every thing that is non-self. The mechanism by which it accomplishes this is the IMMUNE SYSTEM.
The Immune system is a complex of different types of “White blood cells”. Each type of cell carrying out specific functions in the defense of the body.
These cells are Neutrophils, Eosinophils, Basophils, Monocytes and Lymphocytes.
Where are these specialized cells made, and what are their various functions?
The Neutrophils, Eosinophils, and Basophils are formed from Stem cells in the bone marrow.
The neutrophil cells are the first cells to attack any bacteria or foreign material entering the body. They call for the help from the Helper “T” lymphocyte cells which surround the invader. Once the invader is surrounded it is chemically attacked by these defenders.
The “T” cells can summon macrophages from the reticuloendothelial system to digest the invader. “B” cells produce immunoglobulins (Antibodies) that attach to the invaders making them recognizeable to the macrophages, that ingest them.
Phagocytes and Macrophages are formed in the reticulo-endothelial system (bone marrow, lymph nodes and in the liver and spleen sinusoids. The function of phagocytes and macrophages are basically that of a scavenger system. Collecting and clearing up any dead cells or other organic debris. These cells also produce Interferon, the body’s anti–viral compound, and also manufacture antibodies against bacterial proteins and toxins that circulate in the plasma.
The Lymphocytes are formed in the bone marrow, but most of them are formed in the lymph nodes, thymus and spleen.
The lymphocytes are the basic cells of the immune system. There are subsets of lymphocytes, Helper “T” cells, Suppressor “T” cells, natural Killer “T” cells, and “B” cells. The “B” cells are responsible for antibody production.
Immunoglobulin M (IgM); Immunoglobulin G (IgG);these two circulate in the blood, whilst immunoglobulin A {IgA) circulates in the saliva and fluids that bathe mucous membranes The genetic material responsible for structure of antibody globulin chains produced by “B” cells, or those found on the surface receptors of the “T” cells undergo genetic rearrangement with the potential for thousands of different products. This provides the basis for recognition of so many thousands of antigens.
As organic SELENIUM is an integral part of the cellular structure of the lymphocytes and other white blood cells; the more deficient the diet is of selenium, the weaker and more ineffective is the body’s immune response to disease.
