IRF7-Associated Immunophenotypes Have Dichotomous Responses to Virus/Allergen Coexposure and OM-85-Induced Reprogramming

High 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 Blood

Cells 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 mice

Brown 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.

Vitamin D deficiency linked to childhood asthma

Researchers at The Kids Research Institute Australia have found children with vitamin D deficiency are more likely to develop asthma.

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

Reticulon-1 and reduced migration toward chemoattractants by macrophages differentiated from the bone marrow of ultraviolet-irradiated and ultraviolet-chimeric mice

By using an anti-reticulon-1 Ab, a role for reticulon-1 in macrophage migration toward both CSF-1 and CCL2 was confirmed.

Critical role of plasmacytoid dendritic cells in regulating gene expression and innate immune responses to human rhinovirus-16

Though HRVs are usually innocuous viruses, they can trigger serious consequences in certain individuals, especially in the setting of IFN synthesis.

Epigenome-wide analysis links SMAD3 methylation at birth to asthma in children of asthmatic mothers

We sought to assess whether the trajectory to asthma begins already at birth and whether epigenetic mechanisms, contribute to asthma inception.

Altered regulatory T-cell fractions and Helios expression in clinically isolated syndrome: clues to the development of multiple sclerosis

These results indicate that T regulatory (Treg) and follicular T regulatory (Tfr) impairment is an early feature in MS.
