Individual compositional parameters like chemotactic signals, adhesiveness, and pore sizes are well known to be sensed by motile cells, providing individual guidance cues for cellular pathfinding. However, motile cells encounter diverse mechanochemical signals at the same time, raising the question of how cells respond to locally diverse and potentially competing signals on their migration routes. Here, we reveal that motile amoeboid cells require nuclear repositioning, termed nucleokinesis, for adaptive pathfinding in heterogeneous mechanochemical microenvironments. Using mammalian immune cells and the amoeba<jats:italic>Dictyostelium discoideum</jats:italic>, we discover that frequent, rapid and long-distance nucleokinesis is a basic component of amoeboid pathfinding, enabling cells to reorientate quickly between locally competing cues. Amoeboid nucleokinesis comprises a two-step cell polarity switch and is driven by myosin II-forces, sliding the nucleus from a ‘losing’ to the ‘winning’ leading edge to re-adjust the nuclear to the cellular path. Impaired nucleokinesis distorts fast path adaptions and causes cellular arrest in the microenvironment. Our findings establish that nucleokinesis is required for amoeboid cell navigation. Given that motile single-cell amoebae, many immune cells, and some cancer cells utilize an amoeboid migration strategy, these results suggest that amoeboid nucleokinesis underlies cellular navigation during unicellular biology, immunity, and disease."}],"author":[{"first_name":"Janina","last_name":"Kroll","full_name":"Kroll, Janina"},{"id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","first_name":"Robert","orcid":"0000-0001-9843-3522","full_name":"Hauschild, Robert","last_name":"Hauschild"},{"first_name":"Arthur","full_name":"Kuznetcov, Arthur","last_name":"Kuznetcov"},{"last_name":"Stefanowski","full_name":"Stefanowski, Kasia","first_name":"Kasia"},{"first_name":"Monika D.","full_name":"Hermann, Monika D.","last_name":"Hermann"},{"orcid":"0000-0001-5145-4609","full_name":"Merrin, Jack","last_name":"Merrin","first_name":"Jack","id":"4515C308-F248-11E8-B48F-1D18A9856A87"},{"id":"3CD37A82-F248-11E8-B48F-1D18A9856A87","first_name":"Lubuna B","orcid":"0000-0001-7180-6050","full_name":"Shafeek, Lubuna B","last_name":"Shafeek"},{"first_name":"Annette","last_name":"Müller-Taubenberger","full_name":"Müller-Taubenberger, Annette"},{"full_name":"Renkawitz, Jörg","last_name":"Renkawitz","orcid":"0000-0003-2856-3369","first_name":"Jörg","id":"3F0587C8-F248-11E8-B48F-1D18A9856A87"}],"oa":1,"date_updated":"2023-11-27T08:47:45Z","article_processing_charge":"Yes (via OA deal)","_id":"13342","pmid":1,"publication_identifier":{"eissn":["1460-2075"],"issn":["0261-4189"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"We thank Christoph Mayr and Bingzhi Wang for initial experiments on amoeboid nucleokinesis, Ana-Maria Lennon-Duménil and Aline Yatim for bone marrow from MyoIIA-Flox*CD11c-Cre mice, Michael Sixt and Aglaja Kopf for EMTB-mCherry, EB3-mCherry, Lifeact-GFP, Lfc knockout, and Myh9-GFP expressing HoxB8 cells, Malte Benjamin Braun, Mauricio Ruiz, and Madeleine T.

Here we present a strategy using finite-element method (FEM) simulations to determine the Green's function of the KPFM probe/insulator/ground system, which allows us to quantitatively extract surface charge. Testing our approach with synthetic data, we find that accounting for the atomic force microscope (AFM) tip, cone, and cantilever is necessary to recover a known input and that existing methods lead to gross miscalculation or even the incorrect sign of the underlying charge. Applying it to experimental data, we demonstrate its capacity to extract realistic surface charge densities and fine details from contact-charged surfaces. Our method gives a straightforward recipe to convert qualitative KPFM voltage data into quantitative charge data over a range of experimental conditions, enabling quantitative CE at the nanoscale.","lang":"eng"}],"isi":1,"article_number":"125605","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2209.01889","open_access":"1"}],"ec_funded":1,"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"},{"_id":"ScienComp"}],"year":"2022","doi":"10.1103/PhysRevMaterials.6.125605","external_id":{"isi":["000908384800001"],"arxiv":["2209.01889"]},"title":"Quantifying nanoscale charge density features of contact-charged surfaces with an FEM/KPFM-hybrid approach","issue":"12","publication":"Physical Review Materials","type":"journal_article","day":"29","status":"public","intvolume":"         6","department":[{"_id":"ScWa"},{"_id":"NanoFab"}],"date_created":"2023-01-08T23:00:53Z","date_published":"2022-12-29T00:00:00Z","article_type":"original","month":"12","language":[{"iso":"eng"}],"publisher":"American Physical Society","scopus_import":"1"}]
