We will attend the “Journées Européenes de Dermocosmétologie” (Lyon, France) the 31th January and 1st February !

The European Center of Dermocosmetology is a french professional association dedicated to the promotion of a high level of education in cosmetology and dermatology. This year, the “Journées Européenes de Dermocosmétologie” will focus on the “intercellular dialogue in the cutaneous tissue: what perspectives in dermocosmetology targeted on weakened skins?” We Read more…

An explanation of assymetric distribution of melanin in the epidermis !

The skin performs important function, including sun protection. Melanin distribution in the epidermis plays a role in photoprotection. Solar radiations induced epidermal DNA damages, mostly in the basal layer, and is an established caused of keratinocytes cancers. Melanin distribution in human epidermis is essentialy located in the basal layer. However, Read more…

A representative hematoxylin and eosin staining of UV-induced skin tumor or skin obtained from SKH-1 mice colonized by S. epidermidis 1457 or MO34, respectively, treated with UV-B for 12 weeks.

Could skin microbiota reduce cancer risk?

Researchers from the Department of Dermatology of the University of California have a commensal strain of Staphylococcus epidermidis that protects against skin neoplasia. This strain produces 6-N-hydroxyaminopurine (6-HAP), a molecule that inhibits DNA polymerase activity. Mice colonized with this strain have a reduced incidence of ultraviolet-induced tumors compared to control mice (colonized with Read more…

Predicting clinical outcomes of wound healing assessment : the limitations of the mice model

Wounds can exhibit impaired healing, as a consequence of pathologic failure to process one of the normal stage of healing. Wound healing impairment could be characteristic of the treatments of chronic wounds due to immobilisation, diabetes, and skin infection. Characterization of compounds efficacy on wound healing parameters is important dermato Read more…

Invasion of Staphylococcus aureus on human keratinocytes : from animals to humans

A staphylococcal infection is a common bacterial skin infection due to staphylococci bacteria. Staphylococcus aureus (S aureus) is part of the nasal microbiome and is the most important of these bacteria in human diseases. About 15–40 per cent of healthy humans are carriers of S aureus, and staphylococcal infection has become a significant public Read more…
