The potency of cytostatic and anti-inflammatory drugs was tested on the oxazolone-induced cutaneous basophil hypersensitivity (CBH) in mice. The challenge reaction was performed early after sensitization in order to minimize B-cell expression; exudative and cellular infiltration was estimated 6 h, 24 h and 48 h after challenge. The potency of drugs was tested at three different periods of immunization: 2 days before or after sensitization or before challenge. Cytostatics act mainly when cells are being committed, a corticoid acts on inflammation linked to committed cells, NSAIDs show inconstant anti-inflammatory effects on this test. D-Penicillamine and levamisole act in the same depressive profile in normal animals. Thus the CBH model appears to be relevant in studying drug activities on inflammation linked to T-cell expression.

Chronic inflammation in the tumour microenvironment (TME) via Th2-polarisation promotes melanoma progression and metastasis, making it a target for immunotherapy. Interleukin (IL)-4 is considered essential for Th2-polarisation in the TME; however, its source remains unknown. Basophils have been postulated as one of its sources.

Erythroderma is a severe and heterogeneous inflammatory skin condition with little guidance on the approach to management in cases of unknown etiology. To guide therapeutic selection, we sought to create an immunophenotyping platform able to identify aberrant cell populations and cytokines in subtypes of erythroderma. We performed high-parameter flow cytometry on peripheral blood mononuclear cells (PBMCs) and whole blood of a patient with refractory idiopathic erythroderma, erythrodermic patients with Sézary syndrome and pityriasis rubra pilaris, and healthy controls.

Activation of immunoglobulin E (IgE)-associated mast cells (MCs) triggers the onset of pro-inflammatory signals associated with type I allergic diseases. Although histone acetylation changes have been associated with inflammatory diseases, the impact of lysine-acetyltransferase (KAT) inhibitors on IgE-mediated MCs function is unclear. Potential anti-allergic effects of the KAT6A inhibitor WM-1119 on IgE-mediated MCs activation and allergic inflammation were examined in this study.

Introduction: Deep mycoses acquired by penetrating trauma to the skin can have varied and sometimes atypical morphological presentations resulting in diagnostic dilemmas and delay in treatment onset. Histopathology can be a useful tool in not only diagnosing but also differentiating various deep mycoses.
Aims And Objectives: To observe various morphological presentations and histopathological features of deep fungal infections.

The effect of atmospheric ultrafine particulate matter (UPM) on respiratory allergic diseases has been investigated for decades; however, the precise molecular mechanisms underlying these effects remain poorly understood. In this study, we used a simulated UPM (sUPM) generated via the spark discharge method to refine black carbon, a core particle that closely mimics real-world UPM, including the size (i.e.
