Karl Landsteiner in the process of trying to learn why. blood transfusions sometimes cause death and other. Antibodies. Cells of the vertebrate acquired immune system produce antibodies with an exquisite specificity for molecules. CIL:10233 Hippocampal neurons. Actin (red); tubulin (green). western blot of bacterial cell extracts . Immune System. organs . and tissues that work together to protect the body from infection. Immune System. includes skin, white blood cells, and special proteins called antibodies. White Blood Cells. immune . Adaptive (specific) Immunity. The general idea:. body . can recognize . specific. . invader and act to destroy . that specific invader.. Adaptive . immunity develops during an individual. ’. s lifetime.. Class Starter: . What are the different blood types that exist?. What determines what type of blood you have?. Why can you die if you were to receive an incompatible blood type?. What determines the different blood groups?. Immune reactions against self antigens—autoimmunity—are an important cause of certain diseases in humans, estimated to affect at least 1% to 2% individuals. the mere presence of . autoantibodies. Assistant Professor. Department of Microbiology. AIIMS, Rishikesh. Learning objectives. By the end of this session student should be able to understand:. Central and peripheral tolerance. Theories of autoimmunity. Rh. Blood Groups, Blood Typing and Blood Transfusions. The discovery of blood groups. .  .                     . Experiments with blood transfusions, the transfer of blood or blood components into a person's blood stream, have been carried out for hundreds of years. Many patients have died and it was not until 1901, when the Austrian Karl Landsteiner discovered human blood groups, that blood transfusions became safer.. Antibodies. Cells of the vertebrate acquired immune system produce antibodies with an exquisite specificity for molecules. CIL:10233 Hippocampal neurons. Actin (red); tubulin (green). western blot of bacterial cell extracts . Immunology . II. Antigens : . its types & . properties. An antigen is any substance which, when introduced . parenterally. into the body, stimulates the production of an antibody with which it reacts specifically and in observable manner.. 2 Features of primary and secondary antibody response Primary response Secondary response Time lag after immunization Usually 5-10 days Usually 1-3 days Peak response Smaller Larger Antibody is The following guidelines reflect the consensus of the OPTN/UNOS Histocompatibility Committee regarding state-of-the-art practicthat will serve the best interest of patients and help the OPTN/UNOS achi .. . Paul Ehrlich had first introduced the concept of autoimmunity; he termed this condition as “horror . autotoxicus. ”.. AUTOIMMUNITY. Normally immune system does not react to its own antigens due to a protective mechanism called tolerance. .
