PLEASE PUT A REFERENCE.

THANKS.

Consider a naive T cell that expresses a T cell receptor that has specificity for a self peptide bound to MHC and a naive B cell that expresses a B cell receptor which binds a self protein with high affinity. What natural mechanisms exist that prevent the activation of these cells when they encounter self antigens?

Answer 1

T cell are cellular cell

And b cell are humeral cell

And b cell only fight the antigen if microorganisms will come..

And the t cell remember the antigen are also have the memory cell

If antigen will come they fight the pathogen and antigen antibody reaction occur to prevent the infection..
