Biographical Sketch 
Harry W. Schroeder, Jr. (b. 1952), Professor, completed his undergraduate studies in Chemistry (B.S., 1974) at Texas A&M University (College Station, TX). He earned his M.D. (1981) and Ph.D. (1979) with Dr. Bert O'Malley at Baylor College of Medicine (Houston, TX). After completing an Internal Medicine residency at the University of Kentucky (Lexington, KY) in 1984, he trained in Clinical Genetics with Dr. Arno Motulsky at the University of Washington (Seattle, WA), and in molecular immunology with Dr. Roger Perlmutter at the Howard Hughes Medical Institute (Seattle, WA). He was recruited to UAB in 1988 where he has continued to pursue interests in the genetics of diseases of immune function. In 1995-1996, he spent a sabbatical year in the laboratory of Dr. Klaus Rajewsky at the Institute for Genetics of the University of Cologne (Cologne, Germany).



Research/Clinical Interest
Title
The Development and Function of Lymphocyte Antigen Receptors. &Genetics of Primary Immune Deficiency Diseases
Description
Although at first glance the power of the mechanisms used to diversify the B- and T-cell antigen receptors appear generate repertoires of random diversity, closer examination reveals striking constraints that are preserved across evolution. The implication is that violation of these constraints programs could lead to immune dysfunction, and thus to disease. Dr. Schroeders group has shown that immunoglobulins belonging to categories outside these constraints are progressive eliminated during development. He has used cre-loxP gene targeting to generate mice wherein the DH locus has been altered to force expression of polyclonal antibody repertoires that lie outside these normal constraints. In these mice, B cell numbers are reduced, responses to T-independent antigens decline in a co-dominant manner, responses to T-dependent antigens and autoantigens are affected in a dominant manner, and autoantibodies can be detected at a very young age. The mechanisms that regulate the normally regulate the repertoire the contribution of violations of these constraints to the development of disease, including autoimmune disorders, are a major focus of the laboratory. A second focus in the laboratory is the use of classic reverse genetics techniques to elucidate the mechanisms that underlie the development of common variable immune deficiency, the most common primary immune deficiency under the care of clinical immunologists.
