The Drosophila (fruit fly) kidney consists out of the Malpighian tubules and nephrocytes, the latter representing the homologue cells to mammalian kidney podocytes, as they share a high similarity in morphology and the molecular make-up of the filtration barrier. One major functional role of nephrocytes is to filter and endocytose factors from the haemolymph (blood). This is crucial for fly physiology in states of health and disease, as Drosophila has an open circulatory system. The group of Dr. Sybille Köhler therefore investigates the role of nephrocytes as key modulators of fly physiology in disease states such as diabetes and during aging. In detail, inter-organ signalling including the cross-talk between nephrocytes and the heart, immune system and gut are investigated. In addition, nephrocytes serve as a great tool to study molecular mechanisms such as mechanosensation and protein function. The findings obtained within the fly model will be translated into the mammalian organism to understand mechanisms during podocyte injury in greater detail.
