Biological Responses to Ultraviolet Radiation and the Effect of Intra-s Checkpoint Inhibition on Ultraviolet Radiation-induced Mutagenesis

Sunlight emits a spectrum of electromagnetic radiation that includes ultraviolet, visible, and infrared wavelengths. It is widely accepted that the ultraviolet radiation (UVR) component is responsible for the mutagenic and carcinogenic effects of sunlight. UVR is further subdivided into three wavelength ranges: UVC (100-280 nm), UVB (280-315 nm) and UVA (315-400 nm) and each of these induce dif...

Biological Effects Induced by Ultraviolet Radiation in Human Fibroblasts

As the most superficial body organ, skin plays an important role in protecting the body from environmental damage. The skin is composed of three layers: the epidermis, dermis and subcutaneous tissue. The epidermis, the outermost layer, has as main functions to protect the body against harmful environmental stimuli and to reduce fluid loss. It is a stratified squamous epithelium with several lay...

Effects of ultraviolet radiation on Langerhans cells

Research on penetration of ultraviolet (UV) radiation into human skin shows that about 20% of UVA and 10% of UVB can reach the basal layer of the epidermis. As a consequence, Langerhans cells (LCs), located in suprabasal layers, are subject to the influence of the two types of UV radiation. This phenomenon leads to quantitative and qualitative alterations in LCs, including reduction in their nu...
