Ricardo Aguiar, M.D., Ph.D.
Professor of Medicine, Biochemistry, Microbiology, and Immunology
Lymphoma Biology
BCR signaling, transcription factor deregulation, and mitochondrial metabolism
Our group focus is on the identification and functional characterization of the genetic abnormalities of hematologic malignancies. We utilize in vitro and in vivo systems, in genome-wide or targeted studies, with the intent of translating these discoveries into clinical initiatives. The principal disease model in our lab is B-cell lymphoma. Active research lines stem from our recently published work and include: 1) The intersection between B-cell receptor signaling and phosphodiesterase 4 (PDE4) as actionable therapeutic targets in mature B cell malignancies; 2) Metabolic imbalance and epigenetic reprogramming in lymphomas; 3) Transcription factor IRF8 and lymphomagenesis.
Related diseases: B cell lymphomas, lymphoid leukemias
Techniques: Genetic modification of cancer cells in vitro using retrovirus and lentivirus, genetic engineering of mouse models, in vivo (mouse) manipulations, multiple signaling assays, genome-wide analysis (DNA, RNA, and protein) of primary human tumors
