Maybe CD4 is mutated or absent so HIV cant bind T helper Maybe it have a low count of Thelper so nothing cant affect it Maybe t helper prevents HIV from replicating Maybe they have more cytotoxic t cells so they can attach affected t helpers Cytotoxic t cells only attack affected cells Maybe t helpers look different entirely and they are unrecognizable so they are not infected These hypotheses Cytotoxic t cells are better and faster in recognizing infected cells The t helper cells are different some way that prevents them form being infected or keep the virus from replicating Cytotoxic cells only affect the t helper At the tcs they kill the infection 1 category Super T H EU2 PLUS EU3 Super tc 9 18 4 Normal protected 1 11 12 17 why They all have the virus no mather what Got a clear exposure M and T type viruses use multiple entry cell in to an infected cell Every hiv needs at least 2 proteins to get into your cell Use multiple proteins to enter Anything the pathogen will bind to is an antigen What aspects of the innate immune response help prevent flu Born with it Fever mucus natural killer cells mucous membranes skin Antigen presenting cells basically suck up antigen form the environment and present to the surface t helper cells t helper cells attract killer cells sntibodies attract cytostic t cells mmeasure the immune response by the antibodies you make memory b cells already ready attenuated flu wouldn t make u sick but have the symptoms Make a new vaccine every year What occurs during a normal response The allergic reaction mechanism the allergic enters the body it is then captured by a macrophage that then produces the cell on its surface www stallergenes com fileadmin flash contact gb swf need the antibodies to respond to the allergens everyone responds to histamine you need t helper cells to have an immune response histamine isn t normally used 10 30 13 lactose intolerant can be caused by the change of bacterial in intestine prevent allegories by desensitization little exposure to eventually lower the lgEs read labels treatments are antihistamine extra copies of a gene means more rna lytic many copies of virus on dna rna interference take a rna mere image the cell will destroy all rma that make that image don t make protein not producing 5 should be used on people autoimmune disease when the adaptive immune response b cells T cells andtibodies are directed against self antigens Useful when your own cells are mutated because the change in the dna changes the protein thus it will be recognized as foreign also when the cells are affected by a virus recognize the viral protein in the bacteria foreign maybe the cells are onfunctioning autoimmunity can also get rid of cells if not needed Autoimmunity is uncrontrolled because you have a bunch of an immune response against your own proteins produced antibodies against your own proteins normal immune response One main example is Hemolytic Anemia antibodies are against proteins on the surface of red blood cells Produce histamine in an allergic response IgE How would u figure out if an autoimmune disease is genetic or environmental Observe identical twins Allergic autoimmune normal
