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.

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...

Sex-Specific Environmental Impacts on Initiation and Progression of Multiple Sclerosis

The immunological mechanisms that contribute to multiple sclerosis (MS) differ between males and females. Females are 2-3 times more likely to develop MS compared to males, however the reason for this discrepancy is unknown. Once MS is established, there is a more inflammatory yet milder form of disease in females whereas males generally suffer from more severe disease and faster progression, neural degradation, and disability.

The Effects of Using the Sun Safe App on Sun Health Knowledge and Behaviors of Young Teenagers: Results of Pilot Intervention Studies

A balanced approach toward sun exposure and protection is needed by young people. Excessive sun exposure increases their risk for skin cancers such as melanoma, whereas some exposure is necessary for vitamin D and healthy bones. We have developed a new iOS smartphone app-Sun Safe-through a co-design process, which aims to support healthy and balanced decision-making by young teenagers (aged 12-13 years).

Impact of a multimodal exercise program on tibial bone health in adolescents with Development Coordination Disorder: an examination of feasibility and potential efficacy

Developmental coordination disorder (DCD) compromises bone health purportedly due to lower levels of physical activity. The potential of an exercise intervention to improve bone health parameters in adolescents with DCD has not previously been studied. This study thus aimed to determine the impact of a multimodal exercise intervention on bone health in this population at-risk of secondary osteoporosis.

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

Sun exposure: An environmental preventer of metabolic dysfunction?

Emerging preclinical findings suggest that some sun exposure is necessary for optimal metabolic health
