Dr. Summer is Assistant Professor in the Department of Medicine. He attends in the Medical Intensive Care Unit and on the Pulmonary Consultation Service at Boston Medical Center.

Dr. Summer’s major research focus is to investigate the relationship between lung and adipose tissue. Recent findings from his lab and others demonstrate that a key signaling axis exists between these tissues. For example, Dr Summer’s lab showed that an adipocyte-derived protein called adiponectin acts in lung to suppress inflammation. Mice deficient in adiponectin develop a spontaneous lung phenotype characterized by emphysema-like changes, and inflammatory vascular lesions.

Ongoing investigations are examining the cellular targets of adiponectin in lung, and determining the signaling mechanisms contributing to adiponectin’s immune suppressive actions in lung. Dr Jason Konter, a post-doctoral pulmonary fellow in Dr Summer’s laboratory is spearheading this investigation.

Dr. Summer is a member of several research groups at the Pulmonary Center: the Stem Cell Biology, the Epithelial Group, and the Developmental Biology Group.
