Reorganization of the actin cytoskeleton could coincide with the activation of several seven transmembrane receptors (7TM receptors) (1). Stimulation of Rho family members leads to rapid remodeling of the actin cytoskeleton and subsequent stress fiber formation and certain 7TM receptors were shown to induce Rho-dependent responses via heterotrimeric G-proteins. Gα12, Gα13 as well as Gαq/11 can link 7TM receptors to RhoA activatio...

Evidences for a functional link between insulin receptor (IR) and β2-adrenergic receptor (β2AR) exist in the mouse heart and in retina and are correlated with the cardiovascular dysfunction under insulin-resistant states1 and a diabetic retinopathy phenotype2. In our recent study we showed that i) IR coexpression reduced β2AR surface expression and accelerated its internalization, ii) provided evidence for d...

Functional interplay between different classes of receptors has emerged as a notable factor of cellular response in health and disease. One of the most prominent examples of cross-talk involves the regulation of glucose metabolism, a major regulatory function under the influence of both insulin receptor (IR) and β2-adrenergic receptor (β2-AR) representing the receptor tyrosine kinases (RTKs) and the seven transmembrane receptors (7TMRs) respecti...
