What types of antigen do T cells NOT recognize? What types of antigen do T cells NOT recognize? self-antigens bacterial antigens cancer antigens processed fragments of protein antigens displayed on surfaces of body cells

Self-antigens are not recognized and attacked by the T cells.

Explanation:

In immunology, the antigens are those substances which are bound by the antibodies. The antigens can be originated from within the bodies, known as self antigens or from outside the body, known as non-self antigens. The immune system identifies and attacks non-self invaders or the foreign harmful objects present in the body. It does not attack the self-antigens under the normal conditions. This is due to the negative selection of T cells of the thymus.
