AbstractIn pancreatic islets, catabolism of tryptophan into serotonin and serotonin receptor 2B (HTR2B) activation is crucial for β-cell proliferation and maternal glucose regulation during pregnancy. Factors that reduce serotonin synthesis and perturb HTR2B signaling are associated with decreased β-cell number, impaired insulin secretion, and gestational glucose intolerance in mice. Albeit the tryptophan-serotonin pathway is dependent on vitamin B6 bioavailability, how vitamin B6 deficiency impacts β-cell proliferation during pregnancy has not been investigated. In this study, we created a vitamin B6 deficient mouse model and investigated how gestational deficiency influences maternal glucose tolerance. Our studies show that gestational vitamin B6 deficiency decreases serotonin levels in maternal pancreatic islets and reduces β-cell proliferation in an HTR2B-dependent manner. These changes were associated with glucose intolerance and insulin resistance, however insulin secretion remained intact. Our findings suggest that vitamin B6 deficiency-induced gestational glucose intolerance involves additional mechanisms that are complex and insulin independent.

Vitamin B6 Deficiency

Purpose: This work reports retinal findings in an adult patient with vitamin B6 deficiency. Methods: A case review of a single patient is presented. Results: A patient with a Roth-type retinal lesion and a history of nonepileptic seizures was found to have lymphocytic colitis. She was treated with pyridoxine, which resolved her seizures and the white-centered hemorrhage. Conclusions: Vitamin B6 deficiency should be considered in the differential diagnosis of patients presenting with white-centered hemorrhages and a history of nonepileptic seizures.
