intraportal infusion, an innate immune response is triggered. This instant blood-mediated
inflammatory reaction (IBMIR) activates the coagulation and complement cascades and
leads to the destruction of 25% of all transplanted islets within minutes, contributing to the
need, in most patients, for islets from more than 1 donor. Low molecular dextran sulfate
(LMW-DS) has been shown in experimental settings to inhibit IBMIR. Methods.
