nPOD is a diabetes research project, funded by the non-profit JDRF. nPOD supports scientific investigators by providing, without cost, rare and difficult to obtain tissues beneficial to their research. The goals of nPOD are twofold: First to maintain a network of procuring and characterizing pancreas and related tissues (spleen, duodenum, lymph nodes, pancreatic lymph nodes, and peripheral blood) from cadaveric organ donors with type 1 diabetes as well as those who are positive for islet autoantibodies that have yet to develop T1D. Second, to promote collaboration through investigator utilization of tissues and data sharing in an effort to address key immunological, histological, viral, and metabolic questions related to the development of T1D.
