Unraveling the development of cutaneous neurofibromas in neurofibromatosis type 1.

ABSTRACT: Neurofibromatosis type 1 (NF1) is a genetic disorder that leads to the formation of cutaneous neurofibromas (cNFs), benign nerve sheath tumors that develop in the skin and significantly impact the quality of life of patients. cNF development begins with bi-allelic NF1 loss in the Schwann cell (SC) lineage, followed by the recruitment of a complex tumor microenvironment consisting of fibroblasts, immune cells, blood vessels, axons, and a dense extracellular matrix. Despite its high prevalence and clinical impact, the molecular mechanisms underlying cNF formation remain poorly understood. Here, we used an Nf1 knockout (Nf1-KO) mouse model combined with immunohistochemistry and single cell transcriptomics in order to investigate the mechanisms driving cNF development. Our results showed that
