Reduced immune responses in chimeric mice engrafted with bone marrow cells from mice with airways inflammation.During respiratory inflammation, it is generally assumed that dendritic cells differentiating from the bone marrow are immunogenic rather than immunoregulatory.

Clinical, research, and public health implications of poor measurement of Vitamin D statusNew initiatives to develop a standard reference method and the assignment of "true" values to samples provide a solution to these problems.

Tryptophan and arginine catabolic enzymes and regulatory cytokines in clinically isolated syndrome and multiple sclerosisHigher IDO and ARG expression in clinically isolated syndrome and multiple sclerosis provides one sustained homeostatic mechanism to control multiple sclerosis-associated inflammation

Vitamin D and allergic airway disease shape the murine lung microbiome in a sex-specific mannerMaintaining sufficient vitamin D is necessary for optimal lung health, and vitamin D may modulate the lung microbiome in a sex-specific fashion

Higher Serum Immunoglobulin G3 Levels May Predict the Development of Multiple Sclerosis in Individuals With Clinically Isolated SyndromeIgG3 levels and proportions of IgG3 (%IgG) in serum at CIS diagnosis were inversely correlated with the time until conversion to MS

Sun exposure and its effects on human health: Mechanisms through which sun exposure could reduce the risk of developing obesity and cardiometabolic dysfunctionThe cardiometabolic protective effects of ultraviolet radiation and mechanistic pathways through which ultraviolet radiation could be beneficial.

Low vitamin D levels are associated with symptoms of depression in young adult malesResults from studies examining associations between serum 25-hydroxyvitamin D (25(OH)D) concentrations and depressive symptoms are equivocal.

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

Characterization of regulatory dendritic cells differentiated from the bone marrow of UV-irradiated miceIn summary, UV-BMDCs do not express the classical phenotypic or gene expression properties of DCs reported by others as 'regulatory' or 'tolerogenic'.

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

Vitamin D supplementation, moderate sun exposure, and control of immune diseasesThere is considerable debate about the benefits of vitamin D supplementation for multiple sclerosis, allergic asthma, and type 1 diabetes.

Developmental Vitamin D Deficiency in Pregnant Rats Does Not Induce PreeclampsiaPreeclampsia is a pregnancy disorder characterized by hypertension. Epidemiological studies have associated preeclampsia with an increased risk of neurodevelopmental disorders in offspring, such as autism and schizophrenia. Preeclampsia has also been linked with maternal vitamin D deficiency, another candidate risk factor also associated with autism.

Vitamin D deficiency at 16 to 20 weeks' gestation is associated with impaired lung function and asthma at 6 years of ageThis paper examines whether a Vitamin D deficiency during pregnancy affects the child's lung function predisposition towards lung disease such as asthma.

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

Genome-wide association study of vitamin D levels in children: replication in the Western Australian Pregnancy Cohort (Raine) studyThis genome-wide association study (GWAS) utilises data from the Western Australian Pregnancy Cohort (Raine) Study for 25-hydroxyvitamin D (25(OH)D) levels...

Increased levels of solar radiation are associated with reduced type-2 diabetes prevalence: A cross-sectional study of Australian postcodesType-2 diabetes is a leading cause of death and disability. Emerging evidence suggests that ultraviolet radiation or sun exposure may limit its development. We used freely available online datasets to evaluate the associations between solar radiation and type-2 diabetes prevalence across Australia.
