Tenascin-X (TNX) is a member of the extracellular matrix glycoprotein tenascin family, and TNX deficiency leads to Ehlers-Danlos syndrome, a heritable human disorder characterized mostly by skin hyperextensibility, joint hypermobility, and easy bruising. TNX-deficient patients complain of chronic joint pain, myalgia, paresthesia, and axonal polyneuropathy. However, the molecular mechanisms by which TNX deficiency complicates pain […]

A new study by Columbia and Harvard scientists has identified the physiological importance of temperatures for butterfly wings to function properly. Contrary to the common belief that butterfly wings consist primarily of lifeless membranes, the new study demonstrates that they contain a network of living cells needing a range of temperatures for optimal performance. The […]
