Carl Blobel, MD, PhD
Dr. Blobel is a Senior Scientist at Hospital for Special Surgery. His studies are focused on a family of membrane-anchored metalloproteases named ADAMs (a disintegrin and metalloprotease) with an emphasis on their role in tissue degeneration and regeneration, rheumatoid arthritis and angiogenesis.
Selected innovation engagements: Currently Dr. Blobel's lab is focused on understanding how ADAMs regulate the activity of ligands of the epidermal growth factor receptor (EGFR), on elucidating the mechanism underlying the recently discovered roles of ADAMs in angiogenesis, and on their involvement in rheumatoid arthritis and healing of bone fractures and skin wounds.
It is anticipated that his studies will provide interesting new insights into the role of these proteins in cell-cell interactions and signaling and hope that they will help devise new approaches to fighting autoimmune disease and tissue degeneration and to stimulating tissue growth and regeneration.
