Briefly outline the clonal selection theory of adaptive immunity
What will be an ideal response
Immature uncommitted lymphocytes have the genetic material to respond to a large variety of antigens. During the
maturation process, lymphocytes differentiate and become committed to a particular antigen. At all times, there are
a small number of mature lymphocytes developed that are capable of responding to every possible antigen that the
host can genetically react against. When a particular antigen is encountered, the lymphocyte clone(s) capable of
responding to that particular antigen is (are) "selected" or stimulated by the antigen to multiply rapidly and activate
an immune response.
