Inflammatory bowel diseases: interrelationships between dietary vitamin D, exposure to UV radiation and the fecal microbiome

This review explores the interaction of vitamin D, and ultraviolet radiation, with the intestinal innate and adaptive immune systems

The challenges of developing and optimising an assay to measure 25-hydroxyvitamin D in saliva

We have developed an LC-MS/MS assay that accurately measures saliva 25(OH)D3 levels, which correlated with serum levels

Exposure to Solar UVR Suppresses Cell-Mediated Immunization Responses in Humans: The Australian Ultraviolet Radiation and Immunity Study

Higher UVR exposure at antigen sensitization was associated with a reduced delayed-type hypersensitivity response and altered T helper type 17 kinetics

Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humans

The proportion of 25(OH)D3 that undergoes epimerization is greater with oral vitamin D3 supplementation than exposure to UVR in mice, but not in humans

Ultraviolet irradiation of skin alters the faecal microbiome independently of vitamin D in mice

Skin exposure to ultraviolet radiation alters the faecal microbiome, and further investigations to explore the implications of this in health and disease are warranted

Cellular and molecular mechanisms of vitamin D in food allergy

Epidemiological evidence from the past decade suggests a role of vitamin D in food allergy pathogenesis

Vitamin D is crucial for maternal care and offspring social behaviour in rats

These data highlight that early life levels of vitamin D are an important consideration for maternal behavioural adaptations as well as offspring neuropsychiatry

Increased levels of solar radiation are associated with reduced type-2 diabetes prevalence: A cross-sectional study of Australian postcodes

Type-2 diabetes is a leading cause of death and disability. Emerging evidence suggests that ultraviolet radiation or sun exposure may limit its development. We used freely available online datasets to evaluate the associations between solar radiation and type-2 diabetes prevalence across Australia.

Infant study shines new light on eczema prevention

A study led by The Kids Research Institute Australia has suggested vitamin D supplementation in babies is no match for sunlight when it comes to preventing eczema.

Vitamin D deficiency linked to childhood asthma

Researchers at The Kids Research Institute Australia have found children with vitamin D deficiency are more likely to develop asthma.
