Reduced immune responses in chimeric mice engrafted with bone marrow cells from mice with airways inflammation.

During respiratory inflammation, it is generally assumed that dendritic cells differentiating from the bone marrow are immunogenic rather than immunoregulatory.

Vitamin D and immunity

The active form of vitamin D has an important role in calcium metabolism and in bone mineralisation, but the evidence for other health outcomes is mixed,...

The inhibitory and inactivating effects of visible light on SARS-CoV-2: A narrative update

Prior to the coronavirus disease-19 pandemic, the germicidal effects of visible light were well known. This review provides an overview of new findings that suggest there are direct inactivating effects of visible light - particularly blue wavelengths on exposed severe acute respiratory syndrome coronavirus 2 virions, and inhibitory effects on viral replication in infected cells. These findings complement emerging evidence that there may be clinical benefits of orally administered blue light for limiting the severity of COVID-19.

Vitamin D 3 deficiency enhances allergen-induced lymphocyte responses in a mouse model of allergic airway disease

In this study, using a mouse model, we determined whether vitamin D deficiency in utero and during early life modulated the severity of asthma.

Differences in control by UV radiation of inflammatory airways disease in naïve and allergen pre-sensitised mice

Exposure of skin to UV radiation (UVR) prior to allergen exposure can inhibit inflammatory airways disease in mice by reducing effector CD4+ T cells in both...

Ultraviolet irradiation of mice reduces the competency of bone marrow-derived CD11c+

Direct UV irradiation of dendritic cells and Langerhans cells reduces their Ag presenting ability. However, the effects of UV on CD11c(+) cells located...

UV exposure and protection against allergic airways disease

Asthma is a chronic inflammatory disease of the small and large conducting airway mucosa characterised by Th2 cell immunity.

Awake and Alert: Examining the Portrayal of Energy Drinks on TikTok

Energy drinks (EDs) are not recommended for minors' consumption due to a myriad of health risks, but marketing initiatives persist. This study explored the promotion of EDs on TikTok, a platform frequented by children and adolescents.

Increased levels of solar radiation are associated with reduced type-2 diabetes prevalence: A cross-sectional study of Australian postcodes

Type-2 diabetes is a leading cause of death and disability. Emerging evidence suggests that ultraviolet radiation or sun exposure may limit its development. We used freely available online datasets to evaluate the associations between solar radiation and type-2 diabetes prevalence across Australia.
