The role of donor-derived chemokines in islet transplantation

A major challenge of pancreatic islet transplantation is the protection of the already putatively marginal islet cell mass. Our data demonstrate that islets have the capacity to behave in a similar manner to cells of the immune system, recruiting leukocytes from the blood stream. The hypothesis is that islet-derived mediators directly or indirectly affect islet engraftment, function and viability, and serve to further amplify the adaptive immune response. The goals are to characterize the innate immune response to specific stimuli in islet transplantation and to identify therapeutic strategies to improve islet transplant engraftment and survival.

Genetic studies in Transplantation

Despite a marked improvement in renal transplant rejection rates over the last decade, the improvement in long-term allograft survival remains modest. Recent advances from the Human Genome Project have identified numerous regions of genetic variability, both single-nucleotide polymorphisms (SNP's) and microsatellites regions, within genes relevant to transplantation. Delayed graft function (DGF) is a form of acute renal failure resulting in post-transplantation oliguria, increased allograft immunogenicity and decreased long-term survival. Our ongoing research is based on the following two hypothesis: (1) The susceptibility to DGF is modified by inherited genetic polymorphisms that alter the level of response in genes that are known to modify the response to tissue injury; (2) Distinct gene expression patterns can be identified in the transplanted allograft that can predict DGF and that can reliably discriminate complex mechanisms of DGF.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Below are financial relationships with industry reported by Dr. Schroppel during 2015 and/or 2016. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Industry-Sponsored Lectures: MSSM faculty occasionally give lectures at events sponsored by industry, but only if the events are free of any marketing purpose.
