Tailored coordination compounds as multimodal labels for multiscale imaging of mesenteric pathogen transport

Principal investigator: Stefanie Bobe, Cristian A. Strassert
Project number: CRC 1450 A02
Project term: 01/2021–12/2028

We will elucidate the role of capillary mesenteric lymph vessels in peritoneal lymph drainage and inflammatory disease progression. Hence, the coordination-chemical concepts established in the first funding period will be implemented towards small molecules as functional labels. Their biodistribution profiles will be tuned by the amphiphilicity or by specific targeting units; since the chelator can remain invariant, no modification of the localization is expected upon exchange of the central cation. Thus, multiple orthogonal readouts arising from a single label will be used to visualize the early pathogen transport of Y. pseudotuberculosis in mice bridging the gap between different scales and modalities.
