Self-Assembled Nanomaterials for Chronic Skin Wound Healing

Self-Assembled Nanomaterials for Chronic Skin Wound Healing

Posted on by skin_challenges
Chronic wounds can be caused by several underlying molecular and cellular pathophysiological mechanisms, including poor vascularization, excessive extracellular matrix (ECM) degradation by proteases, decreased growth factor activity, and bacterial infection. More effective wound therapies need to address one or more of these mechanisms to significantly advance wound care. Self-assembled nanomaterials may provide new therapeutic options…

Defense or repair: How immune cells are controlled during wound healing

Defense or repair: How immune cells are controlled during wound healing

Posted on by skin_challenges
A Cologne-based research team has discovered that the metabolism of mitochondria, the energy suppliers of cells, in macrophages coordinate wound healing to a significant degree. Macrophages belong to the white blood cells and are also known as scavenger cells. Professor Dr. Sabine Eming and her collaborators and colleagues at the CECAD Cluster of Excellence for…

Research Uncovers New Mechanism that Promotes Wound Healing in Skin

Research Uncovers New Mechanism that Promotes Wound Healing in Skin

Posted on by skin_challenges
A University of California, Irvine-led study identifies a new molecular pathway that promotes the healing of wounds in the skin. Titled, “GRHL3 activates FSCN1 to relax cell-cell adhesions between migrating keratinocytes during wound re-epithelialization,” the study was published in JCI Insight. The molecular pathway identified is controlled by an evolutionary conserved gene called a Grainyhead…

Not all Acne is Equal: Scientists Reveal Strains of C. acnes that Promote Skin Health

Posted on by skin_challenges
A study led by Osaka City University and Okayama University researchers on Caenorhabditis elegans shows that certain strains of the bacteria Cutibacterium acnes actually prolong the nematode’s lifespan and help its innate immune system fight against the pathogen Staphylococcus aureus.     Cutibacterium acnes, a bacteria that is known to cause acne, is also widely…

Apple cider vinegar soaks do not alter the skin bacterial microbiome in atopic dermatitis

Posted on by skin_challenges
Atopic dermatitis is a common skin disease characterized by altered cutaneous immunity in which patients often exhibit lower skin microbiota diversity compared to healthy skin and are prone to colonization by Staphylococcus aureus. Apple cider vinegar has been shown to have antibacterial effects; however, its effects on the skin microbiome have not previously been well-described.…
