  • Once a child is infected with the herpes simplex virus, the virus becomes inactive (dormant) for long periods of time. (uhhospitals.org)
  • Beyond the uncomfortable sores that the virus can cause, HSV is usually harmless. (healthychildren.org)
  • You are most likely to get HSV if you touch the skin of someone who has herpes sores, blisters, or a rash. (medlineplus.gov)
  • But the virus can still be spread, even when no sores or other symptoms are present. (medlineplus.gov)
  • Many people with genital herpes never have sores. (medlineplus.gov)

  • Led by Gregory Smith, associate professor in immunology and microbiology at Northwestern University Feinberg School of Medicine, researchers found that viral protein 1-2, or VP1/2, allows the herpesvirus to interact with cellular motors, known as dynein. (sciencedaily.com)
  • Once the protein has overtaken this motor, the virus can speed along intercellular highways, or microtubules, to move unobstructed from the tips of nerves in skin to the nuclei of neurons within the nervous system. (sciencedaily.com)
  • Yet the herpesvirus uses one protein, no others required, to transport its genetic information over long distances without stopping. (sciencedaily.com)
  • Smith's team conducted a variety of experiments with VP1/2 to demonstrate its important role in transporting the virus, including artificial activation and genetic mutation of the protein. (sciencedaily.com)
  • In one experiment, scientists mutated the virus with a slower form of the protein dyed red, and raced it against a healthy virus dyed green. (sciencedaily.com)
  • Remarkably, this viral protein can be artificially activated, and in these conditions it zips around within cells in the absence of any virus. (sciencedaily.com)
  • Researchers in Pennsylvania say they've successfully stimulated the production of a pain-blocking protein in mice by using a modified herpes virus to attach the appropriate genes onto the animals' DNA. (scienceblog.com)
