Maggie‚ to get sick very easily. More proteins shared‚ less immunosuppression‚ why interest in growing human stem cells. Antigens‚ any molecule or fragment of a molecule that has the POTENTIAL to trigger a specific immune response by lymphocytes. Antibody generating substance. Immunogen‚ a type of antigen that actually DOES induce a specific immune response. Immune cells act to antigen as nonself or as foreign Poor immunogens‚ small molecules not attached to a carrier molecule (hapten). Whole

April 11‚ 2012 The Complement System The complement system is a nonspecific defense mechanism activated in response to invading organisms. This system gets its name from the fact that it complements the action of antibodies. It is the primary mechanism activated by antibodies to kill foreign cells by forming membrane attack complexes. In addition to directly lysing the invading organisms it also reinforces the general inflammatory tactics. It can be activated in two ways: 1. A nonspecific

pathogens and destroy them‚ Produce antibodies to destroy pathogens and create antitoxins that neutralise the toxins produced by the pathogens. Innate immunity: This is an immunity that occurs naturally in a person’s genetic constitution/physiology and doesn’t arise from a previous infection or vaccination‚ this is called natural immunity. Acquired immunity: Acquired immunity can be either active or passive. Active immunity is the development of antibodies in reaction to an antigen and vaccination

Laughter Therapy “Laughter is the best medicine!” We’ve all heard that before‚ but is it true? Studies show 20-25 minutes of laughter every day is healthy for the body. Laughing also helps with depression‚ cancer patients‚ making our hearts healthy. It also strengthens our immune systems‚ relieves stress‚ helps us look younger and so much more. Laughing Therapy relates to positive thinking. Most diseases are related to stress‚ tension depression. When we have tension‚ we start various

of Graves’ disease is dysfunction in the body’s disease fighting immune system. Normal thyroid function is regulated by the pituitary gland‚ when graves’ disease strikes it triggers the production of antibodies to attack a particular protein on the surface of cells in the thyroid. When these antibodies start attacking many things can go wrong including heart and nervous system functions‚ body temperature‚ muscle strength‚ and fluctuations in a women’s menstrual cycle. Although anyone can develop Graves’

Introduction: Over the past three decades we have witnessed a tremendous amount of activity in the area of biosensors. Biosensors are small devices employing biochemical molecular recognition properties as the basis for a selective analysis. The major processes involved in any biosensor system are analyte recognition‚ signal transduction‚ and readout. Due to their specificity‚ speed‚ portability‚ and low cost‚ biosensors offer exciting opportunities for numerous decentralized clinical applications

helper T cells or even a memory T cell; the latter of which is imperative in making vaccines effective. Yet‚ a small lymphocyte may also be a B lymphocyte cell‚ which find themselves as the war factories during a battle against disease; producing antibodies that can lock onto foreign cells like jigsaw pieces‚ disabling them in action. Yet‚ only once activated by a helper T cell will they become plasma cells‚

Researchers from Wyss demonstrated DNA origami in 2012‚ constructing a barrel shaped robotic device‚ putting antibodies in it and programming for leukemia and lymphoma cells. When found‚ the antibody activated the "suicide switch" in the cells‚ causing them to self-destruct through a process called apoptosis‚ Gizmag reported. One problem with the device is that during testing‚ the nanorobots get digested
