Ross Cheloha and Sadeem Ahmad were awarded CRI Post-doctoral Fellowships
Congratulations to Ross Cheloha and Sadeem Ahmad, who have each been awarded a post-doctoral fellowship from the Cancer Research Institute (CRI).
Ross Cheloha (left), a postdoctoral fellow in the Ploegh lab, will investigate how the BCR (B cell receptor) is trafficked within B cells in order to provide means to promote beneficial BCR activity and inhibit detrimental activity. To provide a brief background, B cells help provide immunity against infections and cancer through the action of a protein complex on their surface (B cell receptor, BCR). Abnormal BCR activity can cause B cells to become cancerous or cause autoimmune diseases.
Sadeem Ahmad (right), a postdoctoral fellow in the Hur lab, will investigate the mechanistic basis of "self" vs "non-self" discrimination by the innate immune receptor MDA5. Loss of this discrimination has not only been implicated in immune disorders like Systemic Lupus Erythematosus (SLE), but also finds immense potential in cancer immunotherapy through MDA5-mediated activation of the type I interferon pathway. Therefore, a deeper understanding of the molecular basis for the aberrant "self" recognition by MDA5 would have a significant therapeutic implication for both auto-inflammatory diseases and cancers.
Founded in 1953, the Program in Molecular and Cellular Medicine and the Immune Disease Institute (PCMM/IDI) is a non-profit research institution in Boston, MA, recognized worldwide for its discoveries that increase the body's ability to fight disease and to heal. With the aim of increasing collaborations and scientific synergies, Immune Disease Institute and Children’s Hospital Boston have entered into an affiliation whereby IDI joins seven other interdisciplinary programs as the Program in Cellular and Molecular Medicine. PCMM/IDI is also academically affiliated with Harvard Medical School, and its investigators hold appointments in departments of the medical school.
The breakthroughs of PCMM/IDI scientists are greatly increasing our understanding of the influence of immune defense and inflammation on biomedical discovery, healthcare, and disease management. Visit About Us to learn more.
