Atopic dermatitis (AD) is a common inflammatory skin disorder characterised by hypersensitivity to allergens, eczematous lesions and pruritus. The aim of this study was to comprehensively characterise a murine model of dermatitis and assess the similarity with the human disease, as well as to profile clinically relevant AD therapies. Four repeated topical administrations of oxazolone in the auricular skin of sensitised mice induced morphological features compatible with AD, including redness and swelling, as well as histological changes typical of spongiotic (eczematous) dermatitis and increased plasmatic IgE.

However, the use of this caging creates a dramatic change from an animal's usual microenvironment. Here we sought to examine the effect of MC on physiologic parameters that are stress-responsive in rats.

- Diabetic individuals may be more susceptible to severe COVID-19, but the reasons for this connection are not fully understood.
- Researchers created a human kidney organoid model to study how diabetic conditions affect SARS-CoV-2 infection, finding that diabetic-like organoids had higher viral loads than controls.
- The study also discovered that altering the metabolic processes in kidney cells from diabetic patients could reduce the susceptibility to the virus, suggesting potential new treatment approaches focusing on energy metabolism.
Topical α1- and α2-adrenoreceptor (ADRA1 and 2) agonists are effective in alleviating permanent vasodilation and facial erythema associated with rosacea by inducing skin vasoconstriction. Although β-adrenoreceptor (ADRB) antagonists are used off-label for rosacea, pharmacological and pharmacodynamic data pertaining to these receptors in skin micro-vessels are lacking. Objectives: To analyse the expression of different adrenergic receptors and their contribution to vasoreactivity in skin micro-vessels.
