cells. In recently conducted clinical trials, the use of increasing concentration of lymphodepletion before infusion of autologous tumor infiltrating lymphocytes (TIL) displayed response rates of 49% to 72%. Responses occur at all sites of tumor antigen and appear to be tolerated with many patients in ongoing duration beyond three years. In the latest trial, patients receiving maximum amount of lymphodepletion, 4 of the 25 patients enrolled…

When I think of the body’s immune system, I think of the video game Pac-Man. Pac-Man gobbles up all the little dots in his way, our body works hard to gobble up germs in its way, much the same as Pac-Man. There are also enemies that try to attack Pac-Man and attempt to make him lose a life, in the same way, our body has to defend against viruses that try to attack it. In the game, you are successful if you are able to keep Pac-Man alive by gobbling up everything in its path before they attack…

codominance can occur, for example in human blood. Humans have four blood types: A, B, AB, O, which are determined by antigens on the red blood cells. If the red blood cell has antigen A or B, then no antibodies will be produced against the antigen. If a person has antigen-A then the person has type A blood and antibodies clump type B blood cells, and vice versa. If the person has antigen-A and B then the person has AB blood and lacks A and B antibodies. If a person is an O then he/she has…

specific antigen, it is used to protect or treat a specific disease. This lab is also important because it shows the importance of knowing the blood type of a person so that the person will not receive the wrong type of blood. Blood type O is the universal donor because it has no A or B antigens on the surface of red blood cell. AB is the universal recipient because it has A and B antigens, which means that there aren’t any reactive antibodies in the plasma that will fight against the antigens.…

be able to see what what specific antibodies have been chemically bound to fluorescent dye within the microtubule cytoskeleton and nuclei. Immunohistochemistry could also be used to selectively take images of antigens and proteins in tissue cells because antibodies bind specifically to antigens in biological tissues through CD3 T-cells. Using immunohistochemistry would make it easy to detect where on the cell surface TLR23 is introduced to the pathogen. The anticipated results would be that when…

the infection caused by the pathogen more effectively. 2. The three cell that function as antigen presenting cells (APCs) are B cells, macrophages, and dendritic cells. 3. Slow pathogens seem to be much better suited in their role of causing infection because they stay in the body…

The macrophage can recognize many different pathogens along with dead, diseased or damaged cells and if one is located, the macrophage “eats” the cell. After consumption, the macrophage turns into an antigen presenting cell. It then travels to the lymphatic system where is presents the antigens to either the T or B lymphocytes. Lymphocytes are white blood cells produced by the lymphatic system. The T lymphocytes (T-cell) fight specific pathogens and travel throughout the body. Once…

cells promoting tumor antigens obtained from tumor microenvironments or dead tumor cells, recruitment of activated T-cells to cause responses and circumventing immunosuppression in the tumor microenvironment (Kershaw, Devaud et. 2013). Dendritic cells can present antigens using MHC class I and II molecules by moving to the lymph nodes to expose antigens to T cells upon receiving a stimulus (Vegh , Wang et. 1993). The activated naïve T cells can migrate to region containing antigens and target…

against a specific type of antigen, the immunity remains throughout the life. The span of developed immunity can be lifelong or short. Inheritance inherited from parents and passed to offspring. Adaptive immunity is not passed from the parents to offspring, hence it cannot be inherited. Presence Present at birth Develops during a person’s lifetime and can be short-lived. Allergic Reaction None Immediate…

deregulation of T cell selection, known as negative selection, in the thymus. The incorrect mechanism for screening certain subsets of human cells causes differentiation of auto reactive and self-antigen specific cells to enter the periphery. The self-antigen specific T cells usually recognize myelin antigens located in the CNS such as MOG, PLP, and MBP. These activated cells, through an unknown mechanism, diffuse through the blood brain barrier (BBB) and attack myelin components located in the…
