Account Options. Patents. A portable water purification system has a prefiler, a pumping unit, a reverse osmosis unit, a microbial control unit and a post filter for removing nuclear, biological, chemical and other contaminants from a water source.
1. T-cells mature (develop immunocompetence) in thymus 2. B-cells mature in bone marrow 3. Immunocompetent lymphocytes have unique receptors, committing them to binding with a specific antigen (all 10,000 + receptors are the same) 4. Lymphocytes become immunocompetent before exposure to antigens a.ingle antigen can mobilize many lymphocytes, stimulate production of many antibodies 3. Self-antigens-our cells would be antigens to someone else a. MHC proteins (Major Histocompatibility Complex) on cell surface b. MHC proteins bind to antigens in infected cells.
The cells of the adaptive immune system are lymphocytes â B cells and T cells. B cells, which are derived from the bone marrow, become the cells that produce antibodies. T cells, which mature in the thymus, differentiate into cells that either participate in lymphocyte maturation, or kill virus-infected cells.he adaptive defense consists of antibodies and lymphocytes, often called the humoral response and the cell mediated response. The term âadaptiveâ refers to the differentiation of self from non-self, and the tailoring of the response to the particular foreign invader.
