Injeção estereotáxica de um vetor viral para manipulação genética condicional no Cabo de Rato Spinal

Overview

This study demonstrates a method for achieving spatially restricted gene expression in the mouse spinal cord through stereotaxic injection of a viral vector into the lumbar dorsal horn. This technique allows for targeted gene manipulation, particularly in areas of synaptic contact between primary somatosensory afferents and central nervous system neurons.
