Millions of lives have been lost in the United States alone due to addiction caused by opioid-based pain relief treatment. We probed an alternative, addiction-free strategy to conventional opioid-based pain relief treatment that targets the actual receptors of pain at the very origin of pain perception – the channel protein and pain receptor TRPV1. In […]

Transient receptor potential (TRP) channels sense temperature in organisms ranging from yeast to human but the molecular mechanisms of thermosensation have been an enigma. In our new paper published in NSMB we present structures of the TRP channel TRPV3, which is predominantly expressed in skin keratinocytes, is implicated in thermo-sensation, nociception, itch, maintenance of the skin barrier, wound healing and hair growth, and is associated with numerous human skin diseases, including a genodermatosis known as Olmsted syndrome, atopic dermatitis, psoriasis and rosacea.

AMPA receptor, with an inhibitor (red) bound to the glutamate-binding domains. The location of the cell membrane is shown schematically in gray. Nerve cells in our brain communicate with one another using small neurotransmitter molecules. These come in many shapes and sizes, such as acetylcholine, serotonin and endorphins, allowing the nervous system to shape the way neurons talk to one another. The amino acid glutamate is one of the most common neurotransmitters used to carry excitatory signals.
