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

IRF7-Associated Immunophenotypes Have Dichotomous Responses to Virus/Allergen Coexposure and OM-85-Induced ReprogrammingHigh risk for virus-induced asthma exacerbations in children is associated with an IRF7lo immunophenotype, but the underlying mechanisms are unclear. Here, we applied a Systems Biology approach to an animal model comprising rat strains manifesting high versus low susceptibility to experimental asthma, induced by virus/allergen coexposure, to elucidate the mechanism(s)-of-action of the high-risk asthma immunophenotype.

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

Metabolic dysfunction induced by a high-fat diet modulates hematopoietic stem and myeloid progenitor cells in brown adipose tissue of miceBrown adipose tissue (BAT) may be an important metabolic regulator of whole-body glucose. While important roles have been ascribed to macrophages in regulating metabolic functions in BAT, little is known of the roles of other immune cells subsets, particularly dendritic cells (DCs). Eating a high-fat diet may compromise the development of hematopoietic stem and progenitor cells (HSPCs)-which give rise to DCs-in bone marrow, with less known of its effects in BAT. We have previously demonstrated that ongoing exposure to low-dose ultraviolet radiation (UVR) significantly reduced the 'whitening' effect of eating a high-fat diet upon interscapular (i) BAT of mice.

In “high-risk” infants with sufficient vitamin d status at birth, infant vitamin D supplementation had no effect on allergy outcomes: A randomized controlled trialEarly infancy oral vitamin D supplementation does not appear to reduce the development of early childhood allergic disease

IgG3 + B cells are associated with the development of multiple sclerosisWe have identified previously uncharacterised subsets of IgG3 + B cells and shown them to correlate with autoimmune attacks on the central nervous system
Research
Low-dose UV radiation before running wheel access activates brown adipose tissueWhen combined with physical activity, low-dose UVR may more effectively limit adiposity and modulate metabolic and immune pathways in iBAT

Effects of UVR exposure on the gut microbiota of mice and humansBoth human and murine studies report that multiple exposures to sub-erythemal UV radiation can increase the diversity of the gut microbiome

Vitamin D metabolites are lower with active Crohn’s disease and spontaneously recover with development of remissionWe aimed to characterise vitamin D metabolism in a cohort of patients with active and inactive Crohn’s disease
