Estudo de Cambridge revela potencial para reverter danos nervosos

Pesquisadores da Universidade de Cambridge desenvolveram modelos miniatura de cérebro e medula espinhal humanos cultivados em laboratório, que mostram que fibras nervosas danificadas podem recuperar a capacidade de regeneração sob certas condições.

A equipe construiu circuitos neurais funcionais usando organoides derivados de células-tronco mantidos fisicamente separados em laboratório. Axônios do tecido cerebral cresceram através do espaço para se conectar ao tecido da medula espinhal e desencadear contrações musculares. Essa configuração permitiu o estudo da regeneração ao longo de mais de um ano de desenvolvimento.

Duke University researchers report that boosting the transfer of healthy mitochondria from support cells to sensory neurons reduced pain-like behaviors in mouse models of diabetic and chemotherapy-related peripheral neuropathy, an approach they say could address a root driver of nerve pain rather than simply blocking pain signals.
