Our Research / Unsere Forschung

Male reproduction:

All areas of signaling in reproduction are of interest to our group.
We identify and characterize molecules important for spermatogenesis, early and late activation of spermatozoa and cell-egg interaction. We also focus on cell-cell interaction in testis and prostate cells.

Female reproduction:

This project focuses on the detailed cellular mechanisms in female reproduction and their function and dysfunction in mouse and human. This includes therapeutical approaches to endometriosis, gene regulation of feto-maternal interaction and oocyte development and oocyte aging.

Prostate cancer:

microRNAs play an important role in post transcriptional regulation of the gene regulatory pathways of most cells. This project focuses on the importance of microRNAs for prostate cancer development and progression in animal models as well as in in-vitro experiments.

CEACAMs:

This work deals with the role of CEACAMs in infection, inflammation and wound healing. We characterize the CEACAM mediated cell-cell and cell-pathogene communication, signaling and function. Monoclonal antibodies, glycoproteins, celllines and mouse are generated as tools.
