What stories were you, our readers, taking note of on RELIEF in 2019? As the year winds to a close, it’s a great time to take stock of our coverage of pain research over the past 12 months. So get ready for a Top 10 list of the most popular content published on the site during that time.
Grabbing the number one spot in the Top 10 is a feature article exploring sex differences in chronic pain. This two-parter described how the pain system differs in male vs. female animals, and in women vs. men, focusing on the contribution of hormones, peptides, immune cells, naturally occurring opioids and the response to opioid drugs.
Speaking of immune cells, taking the number two spot in the Top 10 is another feature article–this time it’s a “Pain 101” focusing on how a class of immune cells called microglia contribute to chronic pain. It turns out that these cells play a crucial role by communicating with pain-sensing neurons.
Take a look below at the full Top 10 list. And stay tuned for more coverage of the best in pain research in 2020 and beyond…
In the meantime, best wishes from the RELIEF staff for the holiday season and New Year!
