Hence, as relative concentrations of wild-type and variant viral proteins vary, alteration of both processivity and fidelity of RNA pol results, permitting viruses to adaptively respond to environmental changes, including immune recognition and reaction to evolving cell receptors. As clear evidence exists for viral disruption of leptin function [106] and virus-associated weight gain in humans [107] and monkeys [108] , is it possible the global epidemics of type II diabetes mellitus, insulin resistance, hyperlipidaemia and obesity now prevalent [109] [110] [111] [112] [113] [114] [115] [116] , are just that; epidemics fundamentally caused by viruses that co-opt insulin or leptin or other associated receptors for cell access and generate protein quasispecies that disrupt receptor function? ./cache/cord-318853-mxyxwkhx.txt ./txt/cord-318853-mxyxwkhx.txt
