14 Jun 2017 --- A new study has suggested that vitamin A improves the insulin producing β-cell´s function, for the first time pointing to a key role for vitamin A in the way the body copes with diabetes. The researchers initially discovered that insulin-producing beta-cells contain a large quantity of a cell surface receptor for vitamin A. The researchers believe that the purpose, in this particular case, is that vitamin A plays an important role for the development of beta-cells in the early stages of life, but also for a proper function during the remaining life especially during pathophysiological conditions, i.e some inflammatory conditions.
