Acute Erythemal Ultraviolet Radiation Causes Systemic Immunosuppression in the Absence

Vitamin D is synthesised by ultraviolet (UV) irradiation of skin and is hypothesized to be a direct mediator.

Vitamin D and atopy and asthma phenotypes in children

The purpose of this Review was to give an overview of the recent research into whether a lack of vitamin D contributes to the development of atopy and asthma...

Vitamin D supplementation, moderate sun exposure, and control of immune diseases

There is considerable debate about the benefits of vitamin D supplementation for multiple sclerosis, allergic asthma, and type 1 diabetes.

Characterising nitric oxide-mediated metabolic benefits of low-dose ultraviolet radiation in the mouse: a focus on brown adipose tissue

Non-burning (low-dose) UVR suppresses the BAT 'whitening', steatotic and pro-diabetic effects of consuming a high-fat diet through skin release of nitric oxide

Sun-immune connection

Exposure to ultraviolet radiation damages skin cell DNA but skin cancers develop because ultraviolet radiation also affects the immune system

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
