Centipede Analgesics

In the face of the current opioid crisis, scientists are searching for new and safer painkillers (analgesics). Venomous animals may be useful in the search as their venom can contain peptides with analgesic properties. In fact, researchers recently discovered and characterized an analgesic peptide, dubbed SsmTX-I, that was isolated from the venomous centipede, Scolopendra subspinipes mutilans. This peptide was shown to block a type of potassium channel (Kv2.1) in the body that is involved in sensing […]

Wound healing with fish

Researchers in China have discovered that collagen isolated from the skin of tilapia effectively reduce wound healing time in mice. The usefulness of collagen, a major structural protein found in connective tissues, in wound healing has been known. Using fish proteins instead of typical mammalian sources reduces the risk for potential pathogens. Dr. Jiao Sun (Shanghai Jiaotong University School of Medicine) and colleagues isolated collagen from the skin of tilapia […]
