[HTML][HTML] Insulin signaling in type 2 diabetes: experimental and modeling analyses reveal mechanisms of insulin resistance in human adipocytes

…, L Bergenholm, EM Ekstrand, G Cedersund… - Journal of Biological …, 2013 - ASBMB
Type 2 diabetes originates in an expanding adipose tissue that for unknown reasons
becomes insulin resistant. Insulin resistance reflects impairments in insulin signaling, but …

Insulin signaling–mathematical modeling comes of age

E Nyman, G Cedersund, P Strålfors - Trends in Endocrinology & Metabolism, 2012 - cell.com
Signaling pathways that only a few years ago appeared simple and understandable, albeit
