A new study sheds light on the molecular machinery required for reining in cellular signals that, if unleashed, could result in pathological inflammationResearchers in Japan have identified part of the mechanism responsible for preventing prolonged—and potentially dangerous—activation of immune cells called T lymphocytes (1). Each decorated with a unique surface receptor (TCR) capable of detecting pathogenic foreign proteins, T lymphocytes circulate throughout the body patrolling for invading microorganisms. Upon encounter with rogue proteins, TCRs trigger—via a complex of CD3 signaling proteins—intracellular events that orchestrate release of pro-inflammatory mediators called cytokines….

Their conclusion is based on an analysis of microwave brightness temperature recorded by the Special Sensor Microwave Imager (SSM/I) onboard the F13 satellite.“Having such extreme melting so far north, where it is usually colder than the southern regions is extremely interesting,” Professor Tedesco said. “In 2007, the record occurred in southern Greenland, mostly at high elevation areas where in 2008 extreme snowmelt occurred along the northern coast.”…
