the successful expression of naked plasmid DNA in mouse muscle tissue [108]. A few years later it was reported that the injection of DNA encoding an antigenic protein of influenza virus conferred protective immunity in mice [97]. Many papers have described and reviewed the protective immunity induced by DNA against a large variety of viruses [20]‚ bacteria [90] and protozoa [47] in murine models. DNA immunisation has also been investigated for the treatment of cancer [6] and autoimmune diseases [72]

The scope of my investigation was widely based‚ as there are was so many roads one could take that would lead to the ultimate goal of super immunity. The paths I focused on were; Immunity in animals and how we can learn from

Some immunocompetent cells will never be called to service in our lifetime. True 2. Adaptive immunity is provided only by lymphocytes that secrete antibodies. False 3. Somatic recombination by B cells allows each B cell to form its own unique antibody genes. True 4. It is our genes‚ not antigens‚ that determine what specific foreign
