Cancer-associated fibroblasts (CAFs) are key factors in the tumor microenvironment, which have been implicated in cancer cell progression. It has also been reported that vesicles called exosomes produced by these CAFs play an important role in cancer progression. An Osaka Metropolitan University research group investigated the effect of CAF-derived exosomes on the growth of malignant melanoma cells. They found that CAF-derived exosomes express CD9 and CD63 transmembrane proteins, and that the CD9-positive exosomes may inhibit the growth of malignant melanoma cells.

Atopic dermatitis skin lesions and the lesions produced by infectious complications of the disease look so similar that it makes it impossible for patients to spot the difference and know when to visit their doctor for treatment. But an AI-powered mobile app developed by dermatologists now puts the power of diagnosis in the hands of patients.

By searching for the protein transglutaminase 1 (TGM1) among patients with various autoimmune skin diseases, researchers have successfully identified a separate disease that can be linked to autoimmunity against TGM1. This backward method demonstrates a new way of identifying autoantigens as markers for various diseases. By letting autoantigens point to the disease, diagnosis and treatment can be facilitated, according to the study now published in PNAS.

Researchers reveal correlation between ribotype (RT) strains of Cutibacterium acnes, which are found in human skin, and the lifespan of the nematode Caenorhabditis elegans. Strains RT4 and 8, which are associated with acne in human skin, shortened the lifespan of the nematode, while RT6, which are predominantly found in healthy human skin, did not. Also, it was found that the healthy skin-related RT6 strain of C. acnes improved C. elegans resistance to the pathogenic organism Staphylococcus aureus.
