Prostaglandin E2 imprints a long-lasting effect on dendritic cell progenitors in the bone marrowInjection of BM-differentiated DCs from nonchimeric mice restored the reduced immune responses of PGE2-chimeric mice.
Research
Acute Erythemal Ultraviolet Radiation Causes Systemic Immunosuppression in the AbsenceVitamin D is synthesised by ultraviolet (UV) irradiation of skin and is hypothesized to be a direct mediator.
Research
Modulation of the immune system by UV radiation: More than just the effects of vitamin D?Humans obtain most of their vitamin D through the exposure of skin to sunlight
Research
Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humansThe proportion of 25(OH)D3 that undergoes epimerization is greater with oral vitamin D3 supplementation than exposure to UVR in mice, but not in humans
Research
Direct infant UV light exposure is associated with eczema and immune developmentThis study is the first to demonstrate an association between greater direct UV light exposures in early infancy with lower incidence of eczema
Research
Narrowband UVB phototherapy reduces TNF production by B-cell subsets stimulated via TLR7 from individuals with early multiple sclerosisAt the end of a 60-day course of narrowband UVB phototherapy, administered to individuals with early multiple sclerosis, there were changes in the relative proportions of circulating B-cell subsets. This study investigated phototherapy-associated changes to cytokine responses of B cells when exposed to a TLR7 ligand.
Research
Sun-immune connectionExposure to ultraviolet radiation damages skin cell DNA but skin cancers develop because ultraviolet radiation also affects the immune system
Research
Analysis of the human monocyte-derived macrophage transcriptome and response to lipopolysaccharide provides new insights into genetic aetiology of inflammatory bowel disease.We propose that this system provides a model for the differentiation and adaptation of monocytes entering the intestinal lamina propria.
Research
Molecular actions of Vitamin D in reproductive cell biologyThe aim of this work is to review current metabolic and molecular aspects of the VitD-VitD receptor axis in reproductive medicine
Research
Ultraviolet irradiation of skin alters the faecal microbiome independently of vitamin D in miceSkin exposure to ultraviolet radiation alters the faecal microbiome, and further investigations to explore the implications of this in health and disease are warranted
