Research Overview

Of the 3% of Americans affected with autoimmune diseases such as lupus and scleroderma, most are women of child-bearing age. It is known that environmental triggers, including environmental toxicants, play a role in the development of autoimmunity in humans. One such toxicant is the industrial solvent, trichloroethylene (TCE). The influence of TCE exposure during gestation on autoimmune disease in the offspring is undocumented. It is known that developmental exposure to toxicants can often result in more severe health effects than adult exposure. Thus, assessing the effects of TCE during pregnancy for mother and throughout development for the offspring is Dr. Blossom’s primary research interest. Using an autoimmune-prone mouse strain, Dr. Blossom will determine the effects of developmental exposure to occupationally-relevant doses of TCE on the immune systems of pregnant mice and their offspring exposed during gestation, as well as during other critical time points of immune system development. These results will aid in improved assessment of human risks from TCE, as well as other toxicants. Dr. Blossom conducts research as a member of the Arkansas Center for Birth Defects Research and Prevention.
