Question: How do the Immune System Cells become synsitized.?
does the T or B cells have anything to do with it becoming sensitizedHealth Question & Answer
Answers:
B lymphocytes are the key cells in the adaptive immune system (that part of the immune system that can be sensitized).
Exposure to a previously unknown antigen leads to antigen presenting cells (cells that process the antigen) to migrate to lymph nodes where selection of B cells occurs - a cell with the appropriate level of 'attraction' to the antigen is selected. This cell then undergoes a process called Clonal Expansion, whereby a population of cells are created to produce the same antibody (immunoglobulin).
When the body is undergoes repeat exposure to the antigen, there is therefore a ready population of cells that can respond in significantly less time (hence, the immune system has been sensitized to that particular antigen).
