  • Reovirus particles are composed of an inner protein shell (ie, core) of a diameter of 60 nm, which is surrounded by an outer protein shell (ie, outer capsid) that measures 81 nm in diameter. (medscape.com)
  • Assessment of microglial activation in lesioned sites and protein markers for proinflammatory, such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, interferon (IFN)-γ, and HMGB1 were used to evaluate neuroinflammatory responses and anti-inflammation effects of ω-3 PUFA supplementation.

  • We use the HIV envelope protein (gp120/gp41) as a model system. (stanford.edu)
  • The researchers discovered that, with a single mutation to the Cas12a2 protein, the active site degrades only single-stranded DNA -- a feature especially useful in developing new diagnostics tailored for any of a wide range of viruses. (sciencedaily.com)
  • However, studies on SARS-CoV-2 viruses have shown that autophagy processes are reduced in infected patients, with spike proteins present many months after the initial exposure. (theepochtimes.com)
  • When viruses enter a cell, they may immediately trigger a disease process or may remain quiescent for years. (unboundmedicine.com)
  • Now, a recently discovered CRISPR protein, called Cas12a2, has been found to act as a kind of multi-purpose self-destruct system for bacteria, capable of degrading single-stranded RNA, single-stranded DNA and double-stranded DNA. (sciencedaily.com)
