MamK, a bacterial actin, forms dynamic filaments in vivo that are regulated by the acidic proteins MamJ and LimJ.
Olga Draper,Meghan E. Byrne,Zhuo Li,Seperh Keyhani,Joyce C. Barrozo,Grant J. Jensen,Arash Komeili +6 more
TL;DR: The results suggest that MamK filaments, like eukaryotic actins, are intrinsically stable and rely on regulators for their dynamic behaviour, a feature that stands in contrast to some classes of bacterial actins characterized to date.

Novel MRI Contrast Agent from Magnetotactic Bacteria Enables In Vivo Tracking of iPSC-derived Cardiomyocytes.
Morteza Mahmoudi,Morteza Mahmoudi,Atsushi Tachibana,Andrew B. Goldstone,Y. Joseph Woo,Papia Chakraborty,Kayla R. Lee,Chandler S. Foote,Stephanie Piecewicz,Joyce C. Barrozo,Abdul Wakeel,Bradley W. Rice,Caleb B. Bell,Phillip C. Yang +13 more
TL;DR: The use of a living contrast agent, magneto-endosymbionts (MEs) derived from magnetotactic bacteria for the labeling of iCMs is demonstrated and will accelerate the clinical translation of in vivo MRI monitoring of transplanted stem cell at high spatial resolution and sensitivity.
Characterization of Magneto-Endosymbionts as MRI Cell Labeling and Tracking Agents.

TL;DR: The results demonstrate the potential of magneto-endosymbionts as living MR contrast agents, and provide strong MR contrast when loaded into cells and implanted in tissue, and have r2 relaxivity values comparable to traditional iron oxide nanoparticle contrast agents.
Cell Labeling with Magneto-Endosymbionts and the Dissection of the Subcellular Location, Fate, and Host Cell Interactions
Kayla R. Lee,Abdul Wakeel,Papia Chakraborty,Chandler S. Foote,Lauren Kajiura,Joyce C. Barrozo,Andrea C. Chan,Alexey V. Bazarov,Ryan Spitler,Peter M. Kutny,James M Denegre,Robert A. Taft,Joachim Seemann,Bradley W. Rice,Christopher H. Contag,Brian K. Rutt,Caleb B. Bell +16 more
TL;DR: MEs are used to label mammalian cells for the purpose of cell tracking in vivo, with MRI, and identification of the specific processes involved in ME clearance provides a framework to develop MEs with enhanced retention in mammalian cells.

- 03 Sep 2014
TL;DR: In this article, the authors present an approach for host cells with artificial endosymbionts to communicate with each other to alter a phenotype of the host cell. But their approach is restricted to host cells.
