Abstract: The invention relates to developments in the treatment of diabetes in mammals.

Abstract: The invention relates to a method of preparing a xenotransplantable porcine islet preparation capable upon xenotransplantation of producing porcine insulin in an appropriate recipient mammal, the method including or comprising: (i) harvesting the pancreas of piglets at or near full term gestation, and (ii) extracting islets from a culture of the harvested pancreas using a suitable collagenase, (iii) the culture of the harvested pancreas being a) of mechanically reduced harvested pancreas, and b) a supportive mammalian albumin substantially free of non-human microbiological agents,wherein (at least some stage in the method) the islets are associated with Sertoli cells.

Abstract: The incidence of the autoimmune disease, diabetes mellitus, is well controlled in the nude-obese-diabetic (NOD) mouse model using injections of the A chain fragment (or parts thereof) of the insulin molecule as an antigen in combination with killed cells (or parts thereof) of Haemophilus pertussis, acting as an adjuvant. This leads to the convenient prevention of diabetes in humans using the common "Triple vaccine" (DPT) diphtheria/whooping cough/tetanus vaccine (or versions thereof) in combination with A chain fragment of insulin. This mixture can be given to an at-risk population in which diabetes is expected to occur at an abnormally high rate, or it can be given to the entire population.
