Antibody Self reactive antibodies are not found in significant concentration in normal serum because 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 self reactive B cells are killed by CD8 T cells it is impossible to generate a self-reactive antibody 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 self reactive B cells are killed by CD8 T cells it is impossible to generate a self-reactive antibody ANSWER DOWNLOAD EXAMIANS APP
