RPA facilitates rescue of keratinocytes from UVB radiation damage through insulin-like growth factor-I signalling.

J Cell Sci 2021 May 20. Epub 2021 May 20.

Department of Cell and Molecular Biology, Manipal School of Life Sciences, Manipal Academy of Higher Education, Manipal, Karnataka 576104, India.

UVBR-induced photolesions in genomic DNA of keratinocytes impair cellular functions and potentially determine the cell fate post-irradiation. The ability of insulin-like growth factor-I (IGF-I) to rescue epidermal keratinocytes after photodamage via apoptosis prevention and photolesion removal was recently demonstrated using in vitro 2D and 3D skin models. Given the limited knowledge of specific signalling cascades contributing to post-UVBR IGF-I effects, we used inhibitors to investigate the impact of blockade of various signalling mediators on IGF-I photoprotection.

Sensory neuron-derived TAFA4 promotes macrophage tissue repair functions.

Nature 2021 Jun 19;594(7861):94-99. Epub 2021 May 19.

Aix Marseille Univ., CNRS, INSERM, CIML, Centre d'Immunologie de Marseille-Luminy, Marseille, France.

Inflammation is a defence response to tissue damage that requires tight regulation in order to prevent impaired healing. Tissue-resident macrophages have a key role in tissue repair, but the precise molecular mechanisms that regulate the balance between inflammatory and pro-repair macrophage responses during healing remain poorly understood. Here we demonstrate a major role for sensory neurons in promoting the tissue-repair function of macrophages. Read More

Role of ingestible carotenoids in skin protection: A review of clinical evidence.

Photodermatol Photoimmunol Photomed 2021 May 5. Epub 2021 May 5.

IUF - Leibniz Research Institute for Environmental Medicine, Düsseldorf, Germany.

Carotenoids, a class of phytonutrients, have been well established to boost skin's innate resistance against ultraviolet (UV) B-induced erythema (sunburn). Many of the published clinical studies thus far have focused on the measurement of erythema as the primary clinical indicator of skin protection against UVB radiation. More recent studies have shown that carotenoid supplementation provides even more skin protection than previously shown as new clinical and molecular endpoints beyond UVB-induced erythema have been reported.

Mechanisms of Broad-Band UVB Irradiation‒Induced Itch in Mice.

J Invest Dermatol 2021 Apr 1. Epub 2021 Apr 1.

Washington University School of Medicine in St. Louis, St. Louis, Missouri, USA; Department of Anesthesiology, Center for the Study of Itch & Sensory Disorders, Washington University School of Medicine in St. Louis, St. Louis, Missouri, USA.

Although sunburn can produce severe uncontrollable itching, the underlying mechanisms of UV irradiation‒induced itch are poorly understood because of a lack of experimental animal models of sunburn itch. In this study, we established a sunburn-related mouse model and found that broad-band UVB irradiation elicited scratching but not wiping behavior in mice. Using a combination of live-cell calcium ion imaging and quantitative RT-PCR on dorsal root ganglion neurons, H&E staining, immunofluorescence staining of skin preparations, and behavioral testing, in combination with genetic and pharmacological approaches, we showed that TRPV1-positive dorsal root ganglion neurons but not mast cells are involved in broad-band UVB irradiation‒induced itch.

A topical formulation containing quercetin-loaded microcapsules protects against oxidative and inflammatory skin alterations triggered by UVB irradiation: enhancement of activity by microencapsulation.

J Drug Target 2021 Mar 15:1-15. Epub 2021 Mar 15.

Departamento de Ciências Farmacêuticas, Universidade Estadual de Londrina-UEL, Avenida Robert Koch, 60, Hospital Universitário, Londrina, Brazil.

Ultraviolet B (UVB) irradiation causes free radical production, increase inflammation and oxidative stress, thus, supporting the use of antioxidants by topical administration as therapeutic approaches. Quercetin (QC) is a flavonoid with antioxidant activity, however, high liposolubility makes it difficult to remain in the viable skin layer. Thus, this study evaluated whether microencapsulation of QC would enhance its activity in comparison with the same dose of free QC (non-active dose) and unloaded-microcapsules added in formulation for topical administration in a mouse model of UVB irradiation targeting the skin.
