​T cell receptors can discriminate between ____ (self) and ____ (nonself) .

A) ​antigens; MHC markers
B) ​MHC markers; antigens
C) ​MHC markers; antibodies
D) ​B cell receptors; T cell receptors
E) ​IgM; IgD

T Cell Receptors

Proteins found on the surface of T cells that allow these cells to recognize and bind to specific foreign antigens.

MHC Markers

Major histocompatibility complex markers, proteins found on the surfaces of cells that help the immune system recognize foreign substances.

Antigens

Substances that when introduced into the body, trigger an immune response, often by the production of antibodies.

  • Distinguish between self and non-self entities using T cell receptors and Major Histocompatibility Complex (MHC) markers.

Final Answer :
B
Explanation :
T cell receptors (TCRs) are able to recognize antigens presented on major histocompatibility complex (MHC) molecules. MHC molecules are present on all cells in the body and are used to present self-antigens to T cells during development, allowing for the selection of T cells that are able to discriminate self from nonself. Therefore, TCRs are able to discriminate between self (antigens presented on self MHC) and nonself (antigens presented on nonself MHC).
