UVR-induced immunosupression

Despite considerable advances, the exact mechanism whereby UVR can lead to changes in immune responses is not entirely clear at present, and no...

Immune modulation by UV: Role of vitamin D

In this chapter, evidence for and evidence against the involvement of vitamin D in the immunoregulatory properties of UV radiation is presented.

Optimized 25-hydroxyvitamin D analysis using liquid-liquid extraction with 2D separation with LC/MS/MS detection, provides superior precision

The analysis of 25-hydroxyvitamin D3 (25(OH)D3) and related metabolites represents a considerable challenge for both clinical and research laboratories...

The current state of play of rodent models to study the role of vitamin D in UV-induced immunomodulation

Ultraviolet radiation (UVR) from sunlight is immunomodulatory and the main source of vitamin D for humans.

Demographic and clinical predictors of vitamin D status in pregnant women tested for deficiency in Western Australia

This study aimed to describe the vitamin D status of pregnant women in Western Australia and identify predictors of deficiency in pregnancy. A cross-sectional study was conducted using linked data from statewide administrative data collections.

More Than Effects in Skin: Ultraviolet Radiation-Induced Changes in Immune Cells in Human Blood

Cells of the skin and circulation are in constant two-way communication. Following exposure of humans to sunlight or to phototherapy, there are alterations in the number, phenotype and function of circulating blood cells.

The influence of sunlight exposure and sun protecting behaviours on allergic outcomes in early childhood

The dramatic rise in allergic disease has occurred in tandem with recent environmental changes and increasing indoor lifestyle culture. While multifactorial, one consistent allergy risk factor has been reduced sunlight exposure. However, vitamin D supplementation studies have been disappointing in preventing allergy, raising possible independent effects of ultraviolet (UV) light exposure.

Prevalence and predictors of vitamin D deficiency in a nationally representative sample of Australian Aboriginal and Torres Strait Islander adults

Vitamin D deficiency (serum 25-hydroxyvitamin D (25(OH)D) concentration <50 nmol/l) is recognised as a public health problem globally. The present study details the prevalence and predictors of vitamin D deficiency in a nationally representative sample (n 3250) of Australian Aboriginal and Torres Strait Islander adults aged ≥18 years. We used data from the 2012-2013 Australian Aboriginal and Torres Strait Islander Health Survey (AATSIHS). Serum 25(OH)D concentrations were measured by liquid chromatography-tandem MS.

In “high-risk” infants with sufficient vitamin d status at birth, infant vitamin D supplementation had no effect on allergy outcomes: A randomized controlled trial

Early infancy oral vitamin D supplementation does not appear to reduce the development of early childhood allergic disease

Low-dose UV radiation before running wheel access activates brown adipose tissue

When combined with physical activity, low-dose UVR may more effectively limit adiposity and modulate metabolic and immune pathways in iBAT
