Abstract

AIMS/HYPOTHESIS:

We hypothesised that nutritional taurine, which is important for the development of the endocrine pancreas and reduces cytokine-induced apoptosis in pancreatic beta cells, would prevent or delay the onset of autoimmune diabetes, if given early in life to the non-obese diabetic (NOD) mouse.

METHODS:

Pregnant NOD mice received a diet supplemented with taurine throughout gestation or until weaning, and the pancreas of the offspring was examined using immunohistochemistry. This was done at postnatal day 14 and after 8 weeks (assessment of insulitis). The animals were also monitored until they became diabetic.

RESULTS:

At 14 days, pancreatic islet mass was significantly greater in animals treated with taurine than in controls. This finding was associated with a greater incidence of islet cell proliferation and a lower incidence of apoptosis. At age 8 weeks the number of islets manifesting insulitis was reduced by more than half, and the area of insulitis was reduced by 90%. Taurine treatment delayed the mean onset time of diabetes from 18 to 30 weeks in females, and from 30 to 38 weeks in males, while 20% of treated females remained free of diabetes after one year.

CONCLUSIONS/INTERPRETATION:

Taurine supplementation in early life altered islet development, reduced insulitis and delayed the onset of diabetes in NOD mice.
