Peripheral sensory pathway. To accurately assess our ability to target macrophages at multiple points along the primary neurons of the peripheral sensory pathway, microscopic examination was performed on tissue from hind paws, thighs (encompassing the sciatic nerve trunk) and spinal column to carry out a survey of CD68⁺DiI⁺ macrophages in the neurovascular bundles, sciatic nerve and spinal cord/DRGs, respectively
