Document Summary
There isn"t an immune response or it is too intense. Lymphocytes b, humans 5 types of immunoglobulins common being g, saliva sweat a, T, matured in thymus, produced as precursors in marrow, becomes t cytototic cells, which reduces infected cells, t helper that carry"s the message between cells and to b lymphocytes. Macrophages, they are recruited for cell immunity first line of response, and response modulated by t cells, phagocyte things that have to be, signal presence of pathogen in the organism and carry message to other cells, Allergies, immunoglobulins recognise it as harmful to body. A misunderstanding of a foreign particle, it is seen as something harmful. Lactose intolerant, break lactose to glucose and galactose, late in life it is developed because immune system attack virus and cells that create lactase some recover because stem cells will divide others will not. Enter cell, destroy cell and they attack the t helper cells making person susceptible to any diseases.
