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.

IgG3 + B cells are associated with the development of multiple sclerosis

We have identified previously uncharacterised subsets of IgG3 + B cells and shown them to correlate with autoimmune attacks on the central nervous system

In “high-risk” infants with sufficient vitamin d status at birth, infant vitamin D supplementation had no effect on allergy outcomes: A randomized controlled trial

Early infancy oral vitamin D supplementation does not appear to reduce the development of early childhood allergic disease

Changes in serum neurofilament light chain levels following narrowband ultraviolet B phototherapy in clinically isolated syndrome

To determine whether serum neurofilament light chain (sNfL) levels are suppressed in patients with the clinically isolated syndrome (CIS) following narrowband ultraviolet B phototherapy (UVB-PT).

Sex-Specific Environmental Impacts on Initiation and Progression of Multiple Sclerosis

The immunological mechanisms that contribute to multiple sclerosis (MS) differ between males and females. Females are 2-3 times more likely to develop MS compared to males, however the reason for this discrepancy is unknown. Once MS is established, there is a more inflammatory yet milder form of disease in females whereas males generally suffer from more severe disease and faster progression, neural degradation, and disability.

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.

Narrowband UVB phototherapy for clinically isolated syndrome: A trial to deliver the benefits of vitamin D and other UVB-induced molecules

The PhoCIS trial provides a fresh approach to re-defining the reported associations of 25(OH)D levels with multiple sclerosis development and progression

UV offers new hope in fight against MS

People at risk of developing multiple sclerosis (MS) have been offered a beacon of hope thanks to research into UV exposure.
