Questions & Step-by-Step Solutions
What type of antigen is recognized by T-cell receptors?
Step 1: Understand what an antigen is. An antigen is a substance that can trigger an immune response in the body.
Step 2: Learn about T-cell receptors. T-cell receptors are special proteins on the surface of T-cells that help them recognize antigens.
Step 3: Know that T-cell receptors do not recognize whole antigens directly. Instead, they recognize small pieces of antigens called peptides.
Step 4: Understand that these peptides must be processed. This means they are broken down into smaller pieces from the original antigen.
Step 5: Learn about Major Histocompatibility Complex (MHC) molecules. MHC molecules are proteins that present the processed peptide antigens on the surface of cells.
Step 6: Realize that T-cell receptors recognize the combination of the peptide and the MHC molecule together.
