Despite their stability, centrioles can disappear during differentiation, such as in oocytes, but little is known about the regulation of their structural integrity. Our previous research revealed that the pericentriolar material (PCM) that surrounds centrioles and its recruiter, Polo kinase, are downregulated in oogenesis and sufficient for maintaining both centrosome structural integrity and MTOC activity. We now show that the expression of specific components of the centriole cartwheel and wall, including ANA1/CEP295, is essential for maintaining centrosome integrity. We find that Polo kinase requires ANA1 to promote centriole stability in cultured cells and eggs. In addition, ANA1 expression prevents the loss of centrioles observed upon PCM-downregulation. However, the centrioles maintained by overexpressing and tethering ANA1 are inactive, unlike the MTOCs observed upon tethering Polo kinase. These findings demonstrate that several centriole components are needed to maintain centrosome structure. Our study also highlights that centrioles are more dynamic than previously believed, with their structural stability relying on the continuous expression of multiple components."}],"oa_version":"Published Version","license":"https://creativecommons.org/licenses/by/4.0/","volume":25,"issue":"1","publication_status":"published","publication_identifier":{"eissn":["1469-3178"]},"language":[{"iso":"eng"}],"file":[{"success":1,"checksum":"53c3ef43d9bd6d7bff3ffcf57d763cac","file_id":"14941","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_name":"2023_EmboReports_PimentaMarques.pdf","date_created":"2024-02-05T12:35:03Z","creator":"dernst","file_size":9645056,"date_updated":"2024-02-05T12:35:03Z"}],"article_processing_charge":"Yes (in subscription journal)","author":[{"first_name":"Ana","full_name":"Pimenta-Marques, Ana","last_name":"Pimenta-Marques"},{"full_name":"Perestrelo, Tania","last_name":"Perestrelo","first_name":"Tania"},{"id":"26E95904-5160-11E9-9C0B-C5B0DC97E90F","first_name":"Patricia","last_name":"Dos Reis Rodrigues","full_name":"Dos Reis Rodrigues, Patricia","orcid":"0000-0003-1681-508X"},{"first_name":"Paulo","last_name":"Duarte","full_name":"Duarte, Paulo"},{"last_name":"Ferreira-Silva","full_name":"Ferreira-Silva, Ana","first_name":"Ana"},{"full_name":"Lince-Faria, Mariana","last_name":"Lince-Faria","first_name":"Mariana"},{"full_name":"Bettencourt-Dias, Mónica","last_name":"Bettencourt-Dias","first_name":"Mónica"}],"title":"Ana1/CEP295 is an essential player in the centrosome maintenance program regulated by Polo kinase and the PCM","citation":{"short":"A.

However, how these cortical flows interact with adjacent cytoplasmic components, changing their form and localization, and how this affects cytoplasmic organization and cell shape remains unclear. Here we show that in ascidian oocytes, the cooperative activities of cortical actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive oocyte cytoplasmic reorganization and shape changes following fertilization. We show that vegetal-directed cortical actomyosin flows, established upon oocyte fertilization, lead to both the accumulation of cortical actin at the vegetal pole of the zygote and compression and local buckling of the adjacent elastic solid-like myoplasm layer due to friction forces generated at their interface. Once cortical flows have ceased, the multiple myoplasm buckles resolve into one larger buckle, which again drives the formation of the contraction pole—a protuberance of the zygote’s vegetal pole where maternal mRNAs accumulate. Thus, our findings reveal a mechanism where cortical actomyosin network flows determine cytoplasmic reorganization and cell shape by deforming adjacent cytoplasmic components through friction forces."}],"oa_version":"Published Version","department":[{"_id":"CaHe"},{"_id":"JoFi"},{"_id":"MiSi"},{"_id":"EM-Fac"},{"_id":"NanoFab"}],"date_updated":"2024-03-05T09:33:38Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","status":"public","_id":"14846"},{"abstract":[{"lang":"eng","text":"The extracellular matrix (ECM) serves as a scaffold for cells and plays an essential role in regulating numerous cellular processes, including cell migration and proliferation.

We have developed a 3D-ECM platform compatible with sample thinning by cryo-focused ion beam milling, the lift-out extraction procedure, and cryo-electron tomography. Our workflow implements cell-derived matrices (CDMs) grown on EM grids, resulting in a versatile tool closely mimicking ECM environments. This allows us to visualize ECM for the first time in its hydrated, native context.

While the BZ reaction originates from the domain of inorganic chemistry, it shares remarkable similarities with actin polymerization, including the characteristic propagating waves, which are influenced by geometry and external fields, and the emergent collective behavior. Starting with a general description of emerging patterns, we elaborate on single droplets or cell-level dynamics, the influence of geometric confinements and conclude with collective interactions. Comparing these two systems sheds light on the universal nature of self-organization principles in both living and inanimate systems.","lang":"eng"}],"oa_version":"Published Version","article_processing_charge":"Yes","author":[{"first_name":"Michael","id":"3BE60946-F248-11E8-B48F-1D18A9856A87","full_name":"Riedl, Michael","orcid":"0000-0003-4844-6311","last_name":"Riedl"},{"first_name":"Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","full_name":"Sixt, Michael K","orcid":"0000-0002-6620-9179","last_name":"Sixt"}],"title":"The excitable nature of polymerizing actin and the Belousov-Zhabotinsky reaction","citation":{"chicago":"Riedl, Michael, and Michael K Sixt. “The Excitable Nature of Polymerizing Actin and the Belousov-Zhabotinsky Reaction.” Frontiers in Cell and Developmental Biology.

To the observer it is therefore intriguing when a moving collective exhibits order. Collective motion of flocks of birds, schools of fish or swarms of self-propelled particles or robots have been studied extensively over the past decades but the mechanisms involved in the transition from chaos to order remain unclear. Here, the interactions, that in most systems give rise to chaos, sustain order. In this thesis we investigate mechanisms that preserve, destabilize or lead to the ordered state. We show that endothelial cells migrating in circular confinements transition to a collective rotating state and concomitantly synchronize the frequencies of nucleating actin waves within individual cells. Consequently, the frequency dependent cell migration speed uniformizes across the population. Complementary to the WAVE dependent nucleation of traveling actin waves, we show that in leukocytes the actin polymerization depending on WASp generates pushing forces locally at stationary patches. Next, in pipe flows, we study methods to disrupt the self--sustaining cycle of turbulence and therefore relaminarize the flow. While we find in pulsating flow conditions that turbulence emerges through a helical instability during the decelerating phase. Finally, we show quantitatively in brain slices of mice that wild-type control neurons can compensate the migratory deficits of a genetically modified neuronal sub--population in the developing cortex.

In particular, in close confinements, such as those encountered by dense cell populations during development or regeneration, collective migration can only arise coordinately. Yet, how individuals unify their velocities is often not understood. Focusing on a finite number of cells in circular confinements, we identify waves of polymerizing actin that function as a pacemaker governing the speed of individual cells. We show that the onset of collective motion coincides with the synchronization of the wave nucleation frequencies across the population. Employing a simpler and more readily accessible mechanical model system of active spheres, we identify the synchronization of the individuals’ internal oscillators as one of the essential requirements to reach the corresponding collective state. The mechanical ‘toy’ experiment illustrates that the global synchronous state is achieved by nearest neighbor coupling. We suggest by analogy that local coupling and the synchronization of actin waves are essential for the emergent, self-organized motion of cell collectives.","lang":"eng"}],"intvolume":" 14","month":"09","scopus_import":"1","ddc":["530","570"],"date_updated":"2023-12-13T12:29:41Z","file_date_updated":"2023-09-25T08:32:37Z","department":[{"_id":"MiSi"},{"_id":"NanoFab"},{"_id":"BjHo"}],"_id":"14361","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article"},{"article_number":"5644","citation":{"mla":"Sitarska, Ewa, et al. “Sensing Their Plasma Membrane Curvature Allows Migrating Cells to Circumvent Obstacles.” Nature Communications, vol. 14, 5644, Springer Nature, 2023, doi:10.1038/s41467-023-41173-1.","ama":"Sitarska E, Almeida SD, Beckwith MS, et al.

We identify a curvature-sensing mechanism underlying obstacle evasion in immune-like cells. Specifically, we propose that actin polymerization at the advancing edge of migrating cells is inhibited by the curvature-sensitive BAR domain protein Snx33 in regions with inward plasma membrane curvature. The genetic perturbation of this machinery reduces the cells’ capacity to evade obstructions combined with faster and more persistent cell migration in obstacle-free environments. Our results show how cells can read out their surface topography and utilize actin and plasma membrane biophysics to interpret their environment, allowing them to adaptively decide if they should move ahead or turn away. On the basis of our findings, we propose that the natural diversity of BAR domain proteins may allow cells to tune their curvature sensing machinery to match the shape characteristics in their environment.","lang":"eng"}],"pmid":1,"oa_version":"Published Version","scopus_import":"1","month":"09","intvolume":" 14","publication_identifier":{"eissn":["2041-1723"]},"publication_status":"published","file":[{"file_id":"14365","checksum":"ad670e3b3c64fc585675948370f6b149","success":1,"access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2023-09-25T08:22:58Z","file_name":"2023_NatureComm_Sitarska.pdf","creator":"dernst","date_updated":"2023-09-25T08:22:58Z","file_size":2725421}],"language":[{"iso":"eng"}],"related_material":{"record":[{"id":"14697","status":"public","relation":"dissertation_contains"}]},"volume":14},{"ec_funded":1,"related_material":{"record":[{"id":"14279","status":"public","relation":"research_data"},{"status":"public","id":"14697","relation":"dissertation_contains"}]},"volume":8,"issue":"87","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2470-9468"]},"intvolume":" 8","month":"09","main_file_link":[{"url":"https://doi.org/10.1126/sciimmunol.adc9584","open_access":"1"}],"scopus_import":"1","pmid":1,"oa_version":"Published Version","abstract":[{"lang":"eng","text":"Immune responses rely on the rapid and coordinated migration of leukocytes. Whereas it is well established that single-cell migration is often guided by gradients of chemokines and other chemoattractants, it remains poorly understood how these gradients are generated, maintained, and modulated. By combining experimental data with theory on leukocyte chemotaxis guided by the G protein–coupled receptor (GPCR) CCR7, we demonstrate that in addition to its role as the sensory receptor that steers migration, CCR7 also acts as a generator and a modulator of chemotactic gradients. Upon exposure to the CCR7 ligand CCL19, dendritic cells (DCs) effectively internalize the receptor and ligand as part of the canonical GPCR desensitization response. We show that CCR7 internalization also acts as an effective sink for the chemoattractant, dynamically shaping the spatiotemporal distribution of the chemokine. This mechanism drives complex collective migration patterns, enabling DCs to create or sharpen chemotactic gradients. We further show that these self-generated gradients can sustain the long-range guidance of DCs, adapt collective migration patterns to the size and geometry of the environment, and provide a guidance cue for other comigrating cells. Such a dual role of CCR7 as a GPCR that both senses and consumes its ligand can thus provide a novel mode of cellular self-organization."}],"department":[{"_id":"MiSi"},{"_id":"EdHa"},{"_id":"NanoFab"}],"date_updated":"2023-12-21T14:30:01Z","keyword":["General Medicine","Immunology"],"status":"public","type":"journal_article","article_type":"original","_id":"14274","date_created":"2023-09-06T08:07:51Z","date_published":"2023-09-01T00:00:00Z","doi":"10.1126/sciimmunol.adc9584","publication":"Science Immunology","day":"01","year":"2023","isi":1,"oa":1,"quality_controlled":"1","publisher":"American Association for the Advancement of Science","acknowledgement":"We thank I. de Vries and the Scientific Service Units (Life Sciences, Bioimaging, Nanofabrication, Preclinical and Miba Machine Shop) of the Institute of Science and Technology Austria for excellent support, as well as all the rotation students assisting in the laboratory work (B.
