Antibody Self reactive antibodies are not found in significant concentration in normal serum because self reactive B cells switch to IgA which is all secreted and not present in serum it is impossible to generate a self-reactive antibody self reactive B cells are killed by CD8 T cells B cells that are stimulated via their surface bound antibody in the absence of T cell help to commit suicide self reactive B cells switch to IgA which is all secreted and not present in serum it is impossible to generate a self-reactive antibody self reactive B cells are killed by CD8 T cells B cells that are stimulated via their surface bound antibody in the absence of T cell help to commit suicide ANSWER DOWNLOAD EXAMIANS APP
