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.

Maternal serum vitamin D levels during pregnancy and offspring neurocognitive development

The objective was to determine the association between maternal serum 25(OH)-vitamin D concentrations and behavioural, emotional and language outcomes...

Vitamin D 3 deficiency enhances allergen-induced lymphocyte responses in a mouse model of allergic airway disease

In this study, using a mouse model, we determined whether vitamin D deficiency in utero and during early life modulated the severity of asthma.

Differences in control by UV radiation of inflammatory airways disease in naïve and allergen pre-sensitised mice

Exposure of skin to UV radiation (UVR) prior to allergen exposure can inhibit inflammatory airways disease in mice by reducing effector CD4+ T cells in both...

Vitamin D and atopy and asthma phenotypes in children: a longitudinal cohort study

Vitamin D has been linked in some studies with atopy- and asthma-associated phenotypes in children with established disease,but its role in disease inception...

Vitamin D metabolites are lower with active Crohn’s disease and spontaneously recover with development of remission

We aimed to characterise vitamin D metabolism in a cohort of patients with active and inactive Crohn’s disease

Exposure to Ultraviolet Radiation in the Modulation of Human Diseases

This review focuses primarily on the beneficial effects for human health of exposure to ultraviolet radiation

High Dose Vitamin D supplementation alters faecal microbiome and predisposes mice to more severe colitis

High dose vitamin D supplementation is associated with a shift to a more inflammatory faecal microbiome and increased susceptibility to colitis
