Toll Fate-keepers
Tissue is maintained in best shape by its intrinsic surveillance systems – cell communication via molecular signals that detect and eliminate aberrant cells. Here, using fruit fly wing tissue development as a model, differences in the amounts of proteins called long Toll receptors between adjacent cells are sufficient to induce responses including cytoskeletal changes and signalling, hallmarks of a tissue surveillance system

What is BPoD?
BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
