Can the human body be tricked into defending itself from viral infections? We interviewed Dr. Rajan George, Adjunct Faculty of the University of Alberta’s Pharmacy and Pharmaceutical Sciences Department. Dr. George is also Vice President of Research and Development for the Division of Infection Diseases of ViRexx Medical Co. As part of the team of University of Alberta scientists, a therapeutic vaccine is now being developed which may inoculate against Hepatitis, Anthrax and Avian Flu H5N1.
When exposed to antigenic determinants of the lymphoid organs are B-cells are activated and differentiate into plasma cells. Plasma cells are specialized, differentiated cells that synthesize and secrete specific antibodies against an antigen. Other activated B cells are memory cells. These cells can be activated later to differentiate into plasma cells to produce antibodies more quickly. This antibody production will occur in the future re-entry of antigen into the body and is the basis for long-term immunity.
With the help of secondary antibodies in the detection, classification, or purification of target antigens by binding to the primary antibody that binds directly to the target antigen. Because the vast majority of primary antibodies are produced in only a few species of animals at home, with almost all antibodies of IgG class is easy and inexpensive for manufacturers to produce and deliver ready to use secondary antibodies that are applicable to most methods and systems. From a relatively small number of secondary antibody, there are many options available to the purity, specificity and type of label for a given application.
The immune system of the human body is a very unique and intricate work of art. This bullet point study guide highlights all of the key components of a college level study on the human immune system.
