UV and Vitamin D

Researchers at The Kids Research Institute Australia are continuing to hone in on the effects of ultraviolet radiation and vitamin D on the immune system.

Research

Topical 1,25-dihydroxyvitamin D3 subverts the priming ability of draining lymph node dendritic cells

The active form of vitamin D, 1,25-hydroxyvitamin D(3) [1,25(OH)(2)D(3)] is produced in skin following exposure to sunlight

Research

Maternal vitamin D levels during pregnancy and offspring eating disorder risk in adolescence

This is the first study to link low gestational vitamin D to increased eating disorder risk in female offspring of Caucasian mothers.

Research

Vitamin D deficiency causes airway hyperresponsiveness and increases airway smooth muscle mass in the lungs of female BALB/c mice

We tested whether there is a causal association between vitamin D deficiency, airway smooth muscle (ASM) mass, and the development of airway hyperresponsiveness

Research

Prevalence and Correlates of Observed Sun Protection Behaviors Across Different Public Outdoor Settings in Melbourne, Australia

Skin cancer prevention efforts in Australia have increasingly incorporated a focus on protection during incidental sun exposure. This complements the long-present messages promoting protection in high-risk settings and avoidance of acute intense bouts of sun exposure.

Research

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

Research

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

Research

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

Research

Predictors of vitamin D-containing supplement use in the Australian population and associations between dose and serum 25-hydroxyvitamin D concentrations

The prevalence of vitamin D-containing supplement use was generally low in the Australian population, particularly for single vitamin D supplements

Research

Self-Reported Changes in Sun-Protection Behaviors at Different Latitudes in Australia

The strongest determinants of self-reported sun-protection behavior changes due to concerns about vitamin D were attitudes and location
