Are there differences in immune responses following delivery of vaccines through acutely or chronically sun-exposed compared with sun-unexposed skin?

The review provides the basis for further research into the effects of acute and chronic UV radiation exposure on skin cells in the context of vaccination

Use of linked administrative and laboratory data to confirm that serum 25(OH)D levels in pregnant women can be predicted from satellite estimates of ultraviolet radiation

Serum 25 hydroxyvitamin D [25(OH)D] levels of pregnant women have been linked to various health outcomes in their offspring. Satellite-derived ultraviolet radiation (UVR) data have been used as a proxy for 25(OH)D levels, as individual-level cohort studies are time-consuming, costly and only feasible for common outcomes.

Narrowband UVB phototherapy reduces TNF production by B-cell subsets stimulated via TLR7 from individuals with early multiple sclerosis

At 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.

Low-dose UV radiation before running wheel access activates brown adipose tissue

When 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 humans

Both 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 remission

We aimed to characterise vitamin D metabolism in a cohort of patients with active and inactive Crohn’s disease

Assessing neutrophil subsets in autoimmune disease: Moving away from relying on density?

Neutrophils are the most abundant immune cell in circulation. However, due to a number of technical challenges for researchers, including the neutrophil's short lifespan and difficulties with preservation, they are often discarded during blood processing and thus ignored in cohort studies. As such, the contribution of neutrophils to disease and their involvement in disease mechanisms is less explored compared with other immune cell types.

Circulating Memory B Cells in Early Multiple Sclerosis Exhibit Increased IgA+ Cells, Globally Decreased BAFF-R Expression and an EBV-Related IgM+ Cell Signature

Multiple sclerosis (MS) is an immune-mediated inflammatory disease of the central nervous system that results in demyelination of axons, inefficient signal transmission and reduced muscular mobility. Recent findings suggest that B cells play a significant role in disease development and pathology. To further explore this, B cell profiles in peripheral blood from 28 treatment-naive patients with early MS were assessed using flow cytometry and compared to 17 healthy controls.
