"Our research also suggested that toxins from tick-borne pathogens such as Borrelia burgdorferi (Lyme disease organism) and Babesia microti may cause chronic illness even after the spirochetes or intracellular protozoa (also called apicomplexans) have been killed by antibiotics. People who cannot naturally eliminate biotoxins develop chronic illness.
Selenium and Disease defense: how the immune system works
Selenium has a pivotal role in disease defense because it is critical to both the innate and adaptive arms of the immune system. It is present in the form of the antioxidant enzyme glutathione peroxidase (GPx) in scavenger white blood cells called macrophages that ingest and destroy invading pathogens as part of innate immune defense. When these cells ingest pathogens, they project parts of the invaders (called antigens) on their own cell surfaces to alert the T and B-cells.
T-cells and B-cells form the basis of adaptive or acquired immunity. T-cells are the effectors of ‘cell-mediated’ immunity, while B-cells produce antibodies. T-cells are the ‘helper’ cells of the immune system, and without them none of the various parts of the immune system, including antibody-mediated defense, operates efficiently.
There are two kinds of T-cells: CD4 cells (sometimes called T-helper cells) and CD8 cells, or ‘killer’ T-cells. CD4 cells ‘see’ the antigens displayed on macrophages and then alert and direct the rest of the immune system including killer T cells, neutrophils and antibody-producing B cells to neutralize the attacker.
T- and B-cells, along with macrophages and neutrophils of the innate immune system, contain selenium in its antioxidant enzyme form. Macrophages and neutrophils lose their ability to “kill” pathogens when selenium is deficient; and T-cell numbers (and effectiveness) decline. Both factors contribute to an association between selenium deficiency and greater susceptibility to disease.
1) have your levels of selenium checked
2) supplement if necessary and check levels again
3) after 4-6 months, keep maintenance dose
