Anti-NMDA receptor encephalitis is a disease where antibodies produced by the body’s own immune system attack the NMDA receptors in the brain. What NMDA receptors are? NMDA receptors are electrical impulse controllers in the brain. Their function result in all autonomic functions such as; judgment‚ perception of reality‚ human interaction‚ the formation and retrieval of memory‚ and the control of unconscious activities What encephalitis does? Antibodies are an important part of the body’s defense

Lindsay Turner 4/20/01 White Blood Cells Bacteria exist everywhere in the environment and have continuous access to the body through the mouth‚ nose and pores of skin. Further more‚ many cells age and die daily and their remains must be removed‚ this is where the white blood cell plays its role. According to this quotation‚ without white blood cells‚ also known as leukocytes‚ we would not be able to survive. White blood cells are our body ’s number one defense against infections. They

antigens (HLA) occurs (Fuggle & Martin‚ 2008). This article shows that 23% of renal patients that are awaiting transplantation are sensitized. More females than males have the HLA antigen. It also shows that first time transplants have less HLA antibodies than those that have had transplants in the past. Several approaches to transplant sensitized patients are presently used or have been used in the past. It is important to understand the different techniques but knowing why is just as important

They recognise the same protein that activated T cells. B cells produce antibodies that are the same as T cell receptors as they precisely recognise the protein belonging to the pathogen. The antibodies are then released from the B cells into the blood. They will then meet the pathogen and attach themselves onto it. Killer T cells activate as well if the pathogen is a virus. This enables

The increase in the antibody concentration on day 7 might be caused by A. excessive bleeding B. the entry of bacteria C. recovery from a disease D. the intake of a large amount of antibiotics 49. The antibody concentration increased rapidly on day 21 because the person A. developed a fever. B. received a vaccination. C

animal is born with one’s innate resistance against certain pathogen. At present‚ all immune systems require contact with antigens‚ and they acquire immunity accordingly‚ which is viewed as an outdated concept. There are three possible cases : 1.The antibodies of the parent are transmitted to their fetus through the placenta or colostrum‚ and the infant is also referred to as a passive immunity. 2.A pathogen that is toxic to other species of animals is harmless to any animal‚ for example‚ a human distemper

Human bloods have differences precisely to the presence or absence of certain protein molecules called antigens and antibodies. The antigens can be found on the surface of red blood cells and the antibodies are in the blood plasma. Individuals have different types and combination of these molecules. Blood group is like a trait which we inherit to our parents. The blood group you belong depends on what you have inherited from your parents. There are three types of antigens: A antigen‚ B antigen

substances inside the wells‚ that would interfere with the experiment. When we added the primary antibody to the well‚ and it contained the antigen‚ then the primary antibody would bind to the antigen‚ and if the sample did not contain the antigen‚ then the primary antibody could not bind to the antigen. But in both these situations‚ there would be no color changing reaction‚ because the secondary antibody was added and couldn’t bind to the enzyme substrate‚ which causes the blue color changing reaction

memory B and memory T cells: the primary or the secondary immune response? Definitely the Secondary response. During the Primary immune response when the B cells and T cells are activated from an encounter with an antigen‚ plasma cells release antibodies to destroy the antigen. During the proliferation phase some of the cells produced stay dormant and act as memory cells of the antigen that was previously encountered. If the identical antigen is confronted again the memory cells enlarge and quickly
