Center for Physiology and Biophysics: News of the Day
  1. Scientists discover how antiviral gene works
    It's been known for years that humans and other mammals possess an antiviral gene called RSAD2 that prevents a remarkable range of viruses from multiplying. Now, researchers have discovered the secret to the gene's success: The enzyme it codes for generates a compound that stops viruses from replicating. The newly discovered compound offers a novel approach for attacking many disease-causing viruses.
    Our intestinal microbiome influences metabolism -- through the immune system
    The innate immune system, our first line of defense against bacterial infection, has a side job that's equally important: fine-tuning our metabolism.

  2. Not junk: 'Jumping gene' is critical for early embryo
    A so-called 'jumping gene' that researchers long considered either genetic junk or a pernicious parasite is actually a critical regulator of the first stages of embryonic development, according to a new study.

  3. Cross-species prion adaptation depends on prion replication environment
    A hamster prion that replicated under conditions of low RNA levels in mouse brain material resulted in altered disease features when readapted and transmitted back to hamsters, according to new research.

  4. Caffeine from four cups of coffee protects the heart with the help of mitochondria
    A new study shows that a caffeine concentration equivalent to four cups of coffee promotes the movement of a regulatory protein into mitochondria, enhancing their function and protecting cardiovascular cells from damage.

  5. Of quirky channels and a fond farewell

    This final installment of Generally Physiological concerns F-selective channels, a surprising role for a tryptophan in determining channel identity, and a farewell note from the Executive Editor of The Journal of General Physiology.

(a) Bordetella pertussis...
