T cells andB cells. Put a check () mark in the table spaces below if the characteristic indicates the lymphocyte type. Put a cross (*) mark if III. otherwise. Characteristics T cell В сell Originates in the bone marrow May give rise to plasma cells Immunocompetence happens in bone marrow May give rise to memory cells Include regulatory, helper, and cytotoxic cells Responsible in directly attacking virus-infected cells Produces antibodies Effective against extracellular pathogens Immunocompetence happens in thymus gland Effective against intracellular pathogens Holds a surface meceptor capable of recognizing a specific antigen
Clinical Application: Immune System and Autoimmunity Disease Lymphocytes may be involved in two major types of responses to the presence of potentially threatening foreign substances. In anti- body-mediated immunity, B lymphocytes may produce antibodies that react with specific antigens on an invading cell or molecule. In cell-mediated immunity, T lymphocytes secrete lymphokines that signal other immune responses and often destroy antigen- containing cells directly. The antibody-antigen reactions associated with immune responses have been used by clinical biologists for years. Several examples are given. Think about each example and answer the questions. 1. Biologists often use antibodies to test for the presence of certain antigens in a particular substance. In Lab Exercise 33- Hormones and Lab Exercise 34-Blood, you witnessed demon- strations of this technique. For each antigen listed, indicate the substance tested (e.g., blood, urine) and give a brief summary of the…
