Clinical/Research Interests:
The focus of my lab is to discover and develop new molecular targets to enhance radiotherapy. We are focused on studying prolonged immune suppression after radiation therapy often referred to as systemic lymphopenia. Systemic lymphopenia is seen in 30-40% of patients with cancer after chemoradiotherapy and is observed for up to six months to a year. The biological mechanism of systemic lymphopenia is not clearly understood.
Recently we found that the patients who developed systemic lymphopenia had elevated levels of myeloid-derived suppressor cells (MDSC) when compared to patients who did not develop lymphopenia. We also found that radiation enhances myelopoiesis.
Presently we are elucidating how radiation enhances myelopoiesis and evaluating pharmacological inhibition of MDSC during radiation therapy in the clinic to abrogate systemic lymphopenia and improved survival.
