Response: Cutaneous melanoma is the deadliest of all skin cancers, especially due to its tendency to invade and develop metastases with an incidence of brain metastasis development of 40% to 50% in patients with melanoma stage IV (although the incidence post mortem is 70–90%). We know that the brain microenvironment represents the first line of reaction in favor or against the tumor due to its dual ability to generate an immune-stimulatory or immunosuppressive niche, which will ultimately determine the establishment and growth of melanoma brain metastasis. Among the brain-resident cells, astrocytes are responsible for the maintenance of the brain homeostasis, and subsequent to melanoma brain colonization, they sustain and foster the growth of melanoma cells (more…)
