Email Profile Print Profile Overview Contact Info & Locations Research Areas Antibodies B Cells Epigenetics Gene Expression Leukemia/Lymphoma Special Interests Research Interests Regulation of B cell transcription and development Lymphocyte differentiation proceeds through multiple stages characterized by the expression of distinct sets of genes. My laboratory’s goals include understanding how the nuclear proteins Early B cell Factor (EBF) and Pax5 (B cell-specific activator protein) regulate B lineage specification, commitment and the immune response to antigens. EBF has been identified as a crucial factor for lineage determination. EBF regulates many genes (such as mb-1) involved in assembly of the pre-B and mature B cell receptors for antigen (pre-BCR and BCR). We recently identified EBF as an early mediator of changes in mb-1 gene chromatin structure, including DNA demethylation and enhanced accessibility. Pax5 acts downstream of EBF as an important regulator of the early B cell-specific transcriptome, but is also important at later stages of B cell maturation. Notably, Pax5 is a key factor for establishing B cell lineage commitment. To better understand how these proteins function in B cells, my lab employs a combination of biochemical and genetic methods, including transgenic and gene targeted mice. Ultimately, we wish to understand how regulatory signals are integrated for activation and/or repression of genes that contribute to normal immunity, immune diseases, and cancer.

This survey is about the patient care experience and does not address crucial characteristics like medical decision-making, prescribing the best therapy, and patient outcomes. Responses are measured on a scale of 1 to 5, with 5 being the best score. Learn more about our patient satisfaction survey.
