This is the first study to link low gestational vitamin D to increased eating disorder risk in female offspring of Caucasian mothers.
Injection of BM-differentiated DCs from nonchimeric mice restored the reduced immune responses of PGE2-chimeric mice.
We tested whether maternal vitamin D insufficiency during pregnancy is related to the autism phenotype.
Vitamin D is synthesised by ultraviolet (UV) irradiation of skin and is hypothesized to be a direct mediator.
Inflammatory mediators from peripheral tissues may control dendritic cell (DC) development in the bone marrow.
The anti-inflammatory actions of IL-4 in activated human monocytes may reflect transcriptional regulation of genes involved in TLR signaling pathways.
There is considerable debate about the benefits of vitamin D supplementation for multiple sclerosis, allergic asthma, and type 1 diabetes.
Despite education about the risks of excessive sun exposure, teenagers in Australia are sun-seeking, with sunburn common in summer. Conversely, some regular (time-limited) exposure to sunlight (that avoids sunburn) is necessary for vitamin D and healthy bones and other molecules important for immune and metabolic health. New interventions are thus required to better support teenagers to make healthy and balanced decisions about their sun behaviors.
Population-level ecological studies show type 1 diabetes incidence is inversely correlated with ambient ultraviolet radiation (UVR) levels. We conducted a nested case–control study using administrative datasets to test this association at the individual level.
Although genetic and epidemiological evidence indicates vitamin D insufficiency contributes to multiple sclerosis (MS), and serum levels of vitamin D increase on treatment with cholecalciferol, recent metanalyses indicate that this vitamin D form does not ameliorate disease. Genetic variation in genes regulating vitamin D, and regulated by vitamin D, affect MS risk.
