Main Field(s) of Research, Abstract

The laboratory focuses on the mechanisms involved in the development of obesity-associated insulin resistance and type 2 diabetes. We developed a novel adipose tissue transplantation paradigm to assess the impact of fat pad localization/venous drainage on glucose homeostasis and insulin sensitivity. Moreover, tissue-specific knockout mice are used to determine the impact of candidate genes in the development of obesity-induced insulin resistance.

Main Fields of Research, Keywords

insulin resistance, obesity, adipose tissue inflammation, type 2 diabetes mellitus

Special Techniques and Equipment

Diverse surgical procedures in mice

Education and Training

Training opportunities for PhD students, PostDocs, Postgraduate Course for Medicine candidates and medical disserations are beeing offered.
