Gene regulation by 1,25-dihydroxyvitamin D3 in CD4+CD25+ cells is enabled by IL-2

Vitamin D may be responsible for reducing the development and severity of autoimmune and allergic diseases. Topically applied 1,25-dihydroxyvitamin D(3) (1,25(O

Immune-modifying properties of topical vitamin D: Focus on dendritic cells and T cells

Topical creams containing the active form of vitamin D (1,25-dihydroxyvitamin D3; 1,25(OH)2D3) or analogues of this compound are currently used with some succes

UV inhibits allergic airways disease in mice by reducing effector CD4 T cells

In human asthma, and experimental allergic airways disease in mice, antigen-presenting cells and CD4(+) effector cells at the airway mucosa orchestrate, and CD4

Vitamin D and Sunlight

In a sunny country such as Australia, it’s important to identify how to achieve the right amount of sun exposure for good health. We need to be able to harness the benefits of vitamin D and sunlight while remaining protected from the proven dangers of too much UV radiation.

Mapping the citation network on vitamin D research in Australia: a data-driven approach

Vitamin D research can vary geographically, as vitamin D status is influenced by latitude, season, dietary intake, body mass index, ethnicity, and public health initiatives. Over the last two decades, research on vitamin D has increased in Australia, where the potential for sun exposure (a major source of vitamin D) is high. We aimed to identify key topics and gaps in vitamin D research in Australia using a data-driven approach.

A Gender Lens on User Quality Ratings From Young Teenagers Assessing the Sun Safe App: Comparing Responses From Co-researchers and Participants of Pilot Intervention Studies

We developed the iOS smartphone app Sun Safe to support healthy sun practices in young teenagers (aged 12-13 years). The production involved co-design with young co-researchers (ie, aged 12-13 years) with a health message of using sun protection when the UV index is ≥3. Important features include real-time and location-specific weather data on the UV index and gamified educational content.

Maternal diet during breastfeeding: Could it influence food allergy risk in children?

Human milk is rich in immuno-modulatory factors that have the potential to shape immune development and influence allergy risk in children. In this article, we describe how breast milk may contribute to making the infant less prone to developing allergies.

Developmental vitamin D deficiency increases foetal exposure to testosterone

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders which are more common in males. The 'prenatal sex steroid' hypothesis links excessive sex-steroid exposure during foetal life with the behavioural differences observed in ASD. However, the reason why sex steroid exposure may be excessive remains unclear. Epidemiological studies have identified several environmental risk factors associated with ASD, including developmental vitamin D (DVD) deficiency.

Insights from a trial of narrowband UVB for early multiple sclerosis

There is a greater prevalence of multiple sclerosis (MS), a neurological autoimmune condition, in populations living further from the equator, hypothesised to be due to reduced sunlight exposure. There exists a proven sunlight surrogate therapy for dermatological inflammatory conditions, in the form of narrowband NB-UVB phototherapy. Yet, there is a paucity of randomized trials of the therapeutic delivery of NB-UVB beyond dermatology for conditions with a systemic inflammatory component. 

Modelling vitamin D food fortification among Aboriginal and Torres Strait Islander peoples in Australia

Low vitamin D intake and prevalence of serum 25-hydroxyvitamin D concentration <50 nmol/L among Aboriginal and Torres Strait Islander peoples highlight a need for public health strategies to improve vitamin D status. Since few foods contain naturally occurring vitamin D, food fortification could be a suitable strategy. We aimed to model vitamin D food fortification scenarios among Aboriginal and Torres Strait Islander peoples.
