PEDF-presenting exosomes may be able to prevent metastasis of melanoma

A Northwestern University team has discovered that some non-metastatic melanoma cells carry a signal, pigment epithelium derived factor (PEDF), that can induce immune-mediated killing of metastatic cells, pointing toward a new immunotherapeutic strategy for the disease.

Exosomes mediate communication between cells and have previously been shown to help tumors create an immunosuppressive environment. But in
