Diabetic Neuropathy: Temporarily Reducing Pain

Painful diabetic neuropathy (PDN) can be relieved for months with a non-viral gene therapy, according to research published in the Annals of Clinical and Translational Neurology. Researchers from Northwestern Medicine administered the non-viral gene therapy or a placebo in order to evaluate the safety and efficacy of a plasmid (VM202) containing 2 human hepatocyte growth factor isoforms given by intramuscular injections in patients with PDN. There were 84 patients included in the study who were randomized to either receive injections of 8 or 16 mg VM202 per leg or placebo. Doses were administered on days zero and 14. The researchers…

Spinal Cord Cells Control Pain

Spinal cord cells are responsible for controlling pain and itch, according to research published in the journal Neuron. Researchers from the University of Zurich used genetically modified viruses to interfere with the functions of neurons in mice in order to investigate how neurons contribute to pain and itch processing. The researchers drew on prior findings from 50 years ago, which had demonstrated “Gate Control Theory” of pain – the idea that inhibitory nerve cells in the spinal cord could determine whether a pain impulse from the periphery (from the foot, for example) is relayed to the brain or suppressed. The…
