selects for lymphocytes that are capable of binding antigens
Positive selection of lymphocytes occurs after exposure to a foreign antigen. This process is a part of the adaptive immune response and involves the selection and survival of lymphocytes that are capable of binding antigens. Positive selection ensures that only lymphocytes with functional antigen receptors are allowed to mature and participate in the immune response. It helps in producing a diverse pool of lymphocytes with the ability to recognize and defend against a wide range of pathogens.
