My research in the Pathology department is mainly focused on immunological aspects of B-cell lymphoma. I study interactions of tumor cells with the microenvironment, and signaling pathways in Hodgkin lymphoma and non-Hodgkin lymphomas.

Monoclonal antibodies reactive with hairy cell leukemia
Monoclonal antibodies reactive with hairy cell leukemia were developed to aid in the diagnosis of this subtype of B cell chronic lymphocytic leukemia and to gain better insight into the origin of hairy cells. Three antibodies were found to be of value in the diagnosis of hairy cell leukemia. Antibody B-ly 2 can be considered a pan-B cell reagent and generally reacts similar to CD22 antibodies. Antibody B-ly 6 is reactive with the same antigen as CD11c (p150/95), an antigen that is present on hairy cell leukemia, macrophages,...

Clonal immunoglobulin gene rearrangements in tissues involved by Hodgkin’s disease
The nature of Reed-Sternberg cells, the abnormal cells of Hodgkin’s disease, is controversial. Morphological and immunologic marker studies suggested different cells of origin. To investigate a possible B or T cell origin, immunoglobulin and T cell receptor gene analyses were performed on tissues from 11 patients in early and late stages of Hodgkin’s disease. In addition, the immunologic marker patterns of the Reed-Sternberg cells were determined. Rearrangements of immunoglobulin heavy- and light-chain genes were detected in tissues from five patients, particularly in late stages of the disease when...
