https://medschool.vanderbilt.edu/basic-sciences/wp-content/uploads/sites/101/2020/03/Hodges.mp4   By Hillary Layden Most human cells contain roughly 6.5 feet of DNA, which must be tightly compacted to fit within the nucleus. Cells compact DNA by wrapping it around proteins called histones, forming a DNA-protein complex called chromatin. “Closed” chromatin is tightly compacted and cannot interact with… Read More

Mar. 10, 2020, 8:00 AM by Leigh MacMillan The cell bodies of peripheral sensory neurons that respond to and transmit information about stimuli including touch, temperature and pain reside in the dorsal root ganglia (DRG). DRG neuron hyperexcitability is correlated with chronic pain. Bruce Carter’s group… Read More
