Within tarantula venom, new hope for safe and novel painkillers found

Screening more than 100 spider toxins, Yale researchers identified a protein from the venom of the Peruvian green velvet tarantula that blunts activity in pain-transmitting neurons. The findings, reported in the March 3 issue of the journal Current Biology, show the new screening method used by the scientists has the potential to search millions of different spider toxins for safe pain-killing drugs and therapies.

The researchers note that they tested the spider toxins on only one of a dozen suspected human pain channels. (more…)

Study Explains Skin’s Response to UVA Light

Researchers have strengthened their understanding of how skin cells called melanocytes sense ultraviolet light and act to protect themselves with melanin. In a new study, they report experiments showing that an ion channel well-known elsewhere in the body for its chemical sensitivity, plays a central role in this process.

PROVIDENCE, R.I. [Brown University] — Last year, a team of researchers at Brown University discovered that certain skin cells use a light-sensitive receptor found outside of the eye to sense ultraviolet light and quickly begin pumping out melanin to protect against DNA damage. In a new study, lab members identify a key player in that biomolecular chain of events that could someday become a pharmacological target for improving this protective response. (more…)
