Research interest

The research conducted in the group of Henrik Dimke can be divided into two lines. Focus is directed towards 1) elucidating the regulatory mechanisms involved in maintaining mineral balance (Calcium, Magnesium, and Phosphate) via trans- and paracellular pathways in kidney and intestine. In particular, regulation of poreforming claudins as well as epithelial channels and transporters involved in mineral transport is of interest.  2) Moreover, additional studies are focusing on understanding the role of the endothelium in renal physiology and various forms of kidney disease.

Methods and Techniques

Primary experimental approaches used to study the regulation of these molecular mechanisms, include the use of various targeted transgenic models, histological and molecular biological techniques, in addition to human kidney isolates. These are outlined below.

-          Immunohistochemistry (light-, laser scanning confocal-, multi-photon microscopy)

-          Cloning

-          Cell culture (Transient and stable expression systems)

-          Western blotting

-          Quantitative PCR

-          Studies on human kidney tissue

-          Various transgenic and cell-specific knockout models

-          Metabolic studies of renal function in animals

-          Developmental changes in renal morphology and function.

-          Antibody development and characterization
