            The Leeper laboratory studies the vascular biology of atherosclerosis and aneurysm disease.  We are interested in the molecular mechanisms that mediate vascular disease, and developing new translational therapies directed against them.  Our group uses a combination of hypothesis-free genetic approaches, favoring the concept that insights generated in this manner are likely to have relevance to human disease.  Currently, our major focus is on a process known as ‘programmed cell removal’, or ‘efferocytosis’ (Latin: to carry the dead to the grave’).  We seek to determine why diseased cells accumulate in the atherosclerotic plaque, and how to harness the power of the immune system as a means to reactivate their removal and stabilize the vulnerable lesion.   Our group pursues the goal of true ‘bench-to-bedside’ translation, bringing together interdisciplinary experts spanning the fields of genomics, molecular biology, translational vascular biology, and clinical Vascular Medicine.  Ultimately, we seek to train the next generation of investigators and physician-scientists who will develop a platform of new therapies directed against atherosclerosis, which is now the leading killer worldwide.

Congratulations Leeper Lab Members

Congratulations to lab alumni, Ricky and Alyssa, who both matched their top choice for residency after medical school graduation.   Ricky (internal medicine) and Alyssa (vascular surgery) are both heading to MGH and we wish them the very best as they enter the next phase of their careers!

Congratulations to the Leeper lab and colleagues for publishing in the NEJM the first human evidence that promoting “efferocytosis” (the phagocytic removal of diseased and dying cells) may have a beneficial effect on atherosclerotic cardiovascular disease.
