Immune cells, pictured here in bright teal, occupy the epithelial layers between the skin surface and its stem cells and act as a system regulator. (Photo by: Fuchs lab) Researchers have discovered a regulatory circuit connecting the skin surface to stem cells via Langerhans immune cells (LCs) that act as immune system regulators. They published their results in Science. This circuit acts like a “rheostat” that continuously fine-tunes the stem cells’ response to the environme

Derm.city is pleased to announce the 5th annual short essay competition on the topic of Inclusivity, Diversity and Equity in Dermatology. This essay competition is organized by the Dermatology Industry Taskforce on Inclusion, Diversity and Equity (DiTiDE), an unincorporated, “ad hoc” committee consisting of Canadian life sciences managers and executives, physicians, and allied parties who are committed to improving the patient experience and outcomes of underrepresented skin

In a new study, adding an individualized mRNA-based vaccine to post-surgery pembrolizumab immunotherapy for high-risk melanoma reduced the risk of melanoma recurrence or death by 42% compared with pembrolizumab alone. The findings were announced in a presentation at the ESMO (European Society for Medical Oncology) Congress 2026 in Madrid. According to a press release from the Melanoma Institute Australia, positive results in melanoma suggest this personalized approach may ena

Patients taking tablets containing a vitamin B5 derivative known as pantethine experienced improved psoriasis symptoms

In a study published in the journal Nature Communications, the investigators swabbed more than 30 volunteers at eight body sites representing distinct microenvironments—including the neck, n

New research shows that melanoma cells not only develop resistance to MAPK (Mitogen-Activated Protein Kinase) inhibitors commonly used to treat it, but also actively suppress the immune cells that would otherwise help eliminate melanoma. The study, published in Nature Communications, identified two cell proteins, ABL1 and ABL2, as key drivers of both processes. These proteins help control cell functions such as growth, survival, and communication with other cells, and when th

Children of parents who have been diagnosed with melanoma are twice as likely to develop melanoma themselves, due to biological factors, environmental factors, and behaviours.
