I'm at the start of TEW2 (1 hour in). Tried to find what APC means by googling all sorts of things, but can't seem to find any definition or...
B-cells become Plasma Cells. When a B-cell receptor connects to its specific antigen, a Helper T-cell releases chemicals that tell that B-cell to divide many times. This makes an army of B-cells with the perfectly shaped B-cell receptor to connect to the invader in your body.Many of these B-cells quickly turn into Plasma cells.how/hide words to know. 1  Antibody: a molecule made by B-cells to trap foreign particles and microbes... 2  Molecule: a chemical structure that has two or more atoms held together by a chemical bond. 3  Plasma cell: an immune cell that comes from B-cells and makes and releases antibodies. 4  Receptor: a molecule on the surface of a cell that receives ...
B cells and T cells are the major types of lymphocytes and are derived from hematopoietic stem cells in the bone marrow. B cells are involved in the humoral immune response, whereas T cells are involved in cell-mediated immune response.Both B cells and T cells carry receptor molecules that recognize specific targets.s with B cells, each type of T cell recognizes a different antigen. Killer T cells are activated when their T cell receptor (TCR) binds to this specific antigen in a complex with the MHC Class I receptor of another cell. Recognition of this MHC:antigen complex is aided by a co-receptor on the T cell, called CD8.
