Question

How do B-lymphocytes and T-lymphocytes recognize specific antigens?

Answer 1

• B cell antigen receptors and antibodies bind to intact antigensin the blood and lymph. For antibodies, they can bind to antigens on the surface of pathogens or free in body fluids.
• T cell receptor binding to MHC-antigencomplex. T cell receptors recognise foreign antigens, then convey the message to the nucleus to induce a response. ... The antigensthat TCRs bind are small peptide fragments, or epitopes, displayed by MHC molecules on the surface of cells.

Answer 2

Answer:

B-cells have B-cell Receptors on their surfaces that can recognize million different types of antigens. ... T-cells too have T-cell receptors that detect the antigen on the surface of the Antigen Presenting cells. The antigens are presented to the T-cells through a MHC-Antigen complex
