James Rothman PhD Nobel Laureate Sterling Professor of Cell Biology Director Nanobiology Institute Y ale University 0 OTHER CORONA VIRUSES GENERATE SHORTTERM HUMORAL BUT LONG TERM CELLULAR IMMUNITY. 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.. A. The body has two main mechanisms of defenses. 1. Innate defense mechanisms – first line of defense. A) These defenses are non-specific and . inherited. Immunity Overview. B) Examples:. 1. ) Physical barriers. In short, it is safe to state that immunity refers to the rules and principles that govern diplomatic relations between states and other entities with legal personality within the international system..

The Lymphatic System. THE LYMPHATIC SYSTEM. Lymph. — fluid in the tissue spaces that carries protein molecules and other substances back to the blood. Lymphatic vessels . — permit only one-way movement of lymph. The immune systems consists of organs, cells, and molecules that fight infections. Many other tissues and systems help the immune system. Skin. is a physical barrier to infection. Mucous membranes. trap pathogens entering the body. of certain substances in . the blood and lymph stream. . These . substances are known as antibodies. . This immunity is inborn. . . Antigens. , the foreign substances that attack the body, stimulate the production of antibodies. . HERD IMMUNITY , the soone r we can go back to doing the things we LOVE ! WHY IS HERD IMMUNITY IMPORTANT TO ACHIEVE? When t he majority of a population becomes immune to a virus, it lessens the sp HUMORAL IMMUNE SYSTEM BY: DR. LUNA PHUKAN TDC 5 TH SEM MAJOR : PAPER 5.3 CELL MEDIATED IMMUNE SYSTEM Cell - mediated immune responses involve the destruction of infected cells by cytotoxic T cell Features of adaptive immunity:. Adaptive immunity is characterized by the following:. 1. Antigenic specificity: (. highly specific).. 2. Diversity : . ( each antigen there is specific T-cell and B-cell for it)..
