No I react like this to morons with hubris.

B cells and T cells have membrane attached antibodies with v(d)J derived antigenic determinant sites. B cells have two antigen recognition regions, T cells one referred to as T cell antigen receptor

You’re still wrong. This time you’re confusing antigens with antibodies. Antigens are pieces of foreign substances or organisms which provoke an immune response. Antibodies are part of the immune response. They bind to the invading pathogen in such a way as to disable or kill it. Two different things.

The T cell antigen receptor is used to bind to pathogen major histocompatibility complex sites and initiate biochemical responses (including recruitment of CD4 and CD8 co-receptors) so the pathogen or infected body cell can be destroyed.

It does NOT carry an antibody. That would not make any sense. If it had an antibody attached to the antigen receptor, the T cell would not be able to bind to the MHC and would become useless. What you’re describing is more along the lines of an autoimmune disease.
