As an update, I would like to share a publication that references SCI and our Substance-P antibody. Here Dr. Paul Dolber et al. found Substance P detected immunohistochemically in the sacral parasympathetic nucleus was significantly higher in 12 SCI rats than in 12 spinally intact rats (P = 0.008), suggesting substance P as a plausible candidate for the primary afferent neurotransmitter. raises the possibility that substance P may be important in the afferent limb of the spinal micturition reflex that develops about a week after spinal cord transection. This could provide a clue to alleviating urinary disorders related to SCI.
