Personal History:

Joseph L. Bryant, DVM, directs the IHV's Animal Model Division and Animal Core Facility. A board certified Laboratory Animal Veterinarian with a background in Comparative Medicine, Dr. Bryant's current research program is an extension of work begun at the National Institutes of Health, where he played a major role in developing a transgenic and gene Knockout Program.

His research team at the IHV has created the first transgenic rats whose DNA has been manipulated to incorporate genes of HIV-1. The rat model opens new areas of human HIV/AIDS study for scientists; its potential is enhanced by similarities in the structure of the rat genome with humans. Ongoing studies include the use of the transgenic rat as a model for HIV/drug abuse, HIV-associated skin diseases and HIV-associated neurological diseases.

Other research efforts focus on the mechanisms of human diseases caused by bacteria and viruses and on details of virus replication to develop better therapies and improved or new diagnostics. The current focus of this work is on the continual development of animal models for AIDS and AIDS-associated malignancies, such as Kaposi's sarcoma and B-cell lymphoma, as well as animal models for breast and prostate cancer. The most recent studies in the division involve the development of animal models of b-cell lymphoma as it relates to infectious causes i.e. mycoplasma fermentans, HIV-1 transgenic mouse model of b-cell lymphoma, and the use of natural plant extracts as anti-cancer agents. Currently, we are also working closely with groups from Jamaica and Nigeria.
