Monocyte and macrophage dysfunction has emerged as a fundamental process common to many chronic inflammation diseases and most complications associated with metabolic disorders, and thus has become a major focus for the design of new pharmacological and therapeutic interventions.
Dr. Reto Asmis's lab employs a wide array of biochemical, cell biological, imaging, and translational approaches to explore novel aspects of macrophage biology in the context of human vascular diseases and diabetic complications.
Our approach is to build on fundamental discoveries at the molecular and cellular level and to translate these into animal models and ultimately, into patient settings.
