Integrins constitute a superfamily of transmembrane signaling receptors that play pivotal roles in cutaneous homeostasis by modulating cell growth and differentiation as well as inflammatory responses in the skin. Subrabasal expression of integrins α2 and/or β1 entails hyperproliferation and aberrant differentiation of keratinocytes and leads to dermal and epidermal influx of activated T-cells....

Introduction: As the novel coronavirus pandemic continues to affect people worldwide, immune-mediated inflammatory syndromes related this virus have been reported. SARS Coronavirus-2 infection disease (COVID-19) may accompany various cutaneous symptoms, such as viral exanthems or wheels. These symptoms occur at early course of after that. Cutaneous COVID-19 usually a favorable outcome. Case Pre...

This study aimed to use a mouse model of hypertrophic scarring by mechanical loading on the dorsum of mice to determine whether the nervous system of the skin and inflammation participates in hypertrophic scarring. Results of hematoxylin-eosin and immunohistochemical staining demonstrated that inflammation contributed to the formation of a hypertrophic scar and increased the nerve density in sc...

Allergic contact dermatitis affects about 5% of men and 11% of women in industrialized countries and is one of the leading causes for occupational diseases. In an animal model for cutaneous contact hypersensitivity, we show that mice lacking both known cannabinoid receptors display exacerbated allergic inflammation. In contrast, fatty acid amide hydrolase-deficient mice, which have increased le...

Selective sequestration of inflammatory chemokines is critical for the successful resolution of inflammatory responses in vivo. D6 is an atypical chemokine receptor that scavenges inflammatory chemokines and is pivotal in resolving models of chemokine-driven cutaneous inflammation. We provide evidence that expression of D6 is not limited to the lymphatic endothelium at sites of inflammation as ...

There is a fine balance between inflammation and tumorigenesis. While environmentally induced inflammatory condition can precede a malignant transformation, in other cases an oncogenic change of unknown origin can induce an inflammatory microenvironment that promotes the development of tumors. Regardless of its origin, maintaining the inflammation milieu has many tumor-promoting effects. As a r...

Diphencyprone (DPCP) is a hapten that induces delayed-type hypersensitivity (DTH) reactions and used therapeutically for various conditions including alopecia areata melanoma metastases. Prior work has shown gene expression markers of major T cell subsets (Th1, Th2, Th17) are significantly increased at 3 days after single application DPCP in healthy volunteers. We evaluated the cutaneous proteo...

Angiogenesis and enhanced microvascular permeability are hallmarks of a large number of inflammatory diseases. Although up-regulation of proangiogenic factors such as vascular endothelial growth factor and interleukin-8 have been previously reported in inflamed tissue, the biologic role of endogenous inhibitors of angiogenesis in inflammation has remained unclear. To investigate the biologic ro...

Skin cancer incidence and mortality are higher in men compared with women, but the causes of this sex discrepancy remain largely unknown. UV light exposure induces cutaneous inflammation and neutralizes cutaneous antioxidants. Gr-1(+)CD11b(+) myeloid cells are heterogeneous bone marrow-derived cells that promote inflammation-associated carcinogenesis. Reduced activity of catalase, an antioxidan...
