Interspecies interactions determine growth dynamics of biopolymer- degrading populations in microbial communities

Martin Ackermann

Microbial communities perform essential ecosystem functions such as the remineralization of organic carbon that exists as biopolymers. The first step in mineralization is performed by biopolymer degraders, which harbor enzymes that can break down polymers ...

Label-Free Long-Term Methods for Live Cell Imaging of Neurons: New Opportunities

Georg Fantner, Zahra Ayar Dulabi, Samuel Mendes Leitão

Time-lapse light microscopy combined with in vitro neuronal cultures has provided a significant contribution to the field of Developmental Neuroscience. The establishment of the neuronal polarity, i.e., formation of axons and dendrites, key structures resp ...

Direct In Vivo Activation of T Cells with Nanosized Immunofilaments Inhibits Tumor Growth and Metastasis

Bart Deplancke, Guido Van Mierlo, Jorieke Weiden

Adoptive T cell therapyhas successfully been implementedfor thetreatment of cancer. Nevertheless, ex vivo expansion of T cells byartificial antigen-presenting cells (aAPCs) remains cumbersome andcan compromise T cell functionality, thereby limiting their t ...

Transposon-activated POU5F1B promotes colorectal cancer growth and metastasis

Didier Trono, Laurence Gouzi Abrami, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Julien Léonard Duc, Laia Simo Riudalbas, Alexandre Coudray, Sagane Dind

The treatment of colorectal cancer (CRC) is an unmet medical need in absence of early diagnosis. Here, upon characterizing cancer-specific transposable element-driven transpochimeric gene transcripts (TcGTs) produced by this tumor in the SYSCOL cohort, we ...

Carbon nanotube uptake in cyanobacteria for near-infrared imaging and enhanced bioelectricity generation in living photovoltaics

Ardemis Anoush Boghossian, Alice Judith Gillen, Alessandra Antonucci, Vitalijs Zubkovs, Melania Reggente, Benjamin Paul Johanès Gabriel Lambert, Mohammed Mouhib, Nils Schürgers, Charlotte Elisabeth Marie Roullier

Single-walled carbon nanotubes (SWCNTs) have unique optoelectronic properties that make them suitable for applications ranging from phototherapy to imaging and sensing, but their uptake has mainly been explored in eukaryotic cells. Here the authors explore ...

Regulation of sedimentation rate shapes the evolution of multicellularity in a close unicellular relative of animals

Omaya Pierre Dudin

Significant increases in sedimentation rate accompany the evolution of multicellularity. These increases should lead to rapid changes in ecological distribution, thereby affecting the costs and benefits of multicellularity and its likelihood to evolve. How ...

Intrinsically High Capacity of Animal Cells From a Symbiotic Cnidarian to Deal With Pro-Oxidative Conditions

Gaëlle Delphine Toullec

The cnidarian-dinoflagellate symbiosis is a mutualistic intracellular association based on the photosynthetic activity of the endosymbiont. This relationship involves significant constraints and requires co-evolution processes, such as an extensive capacit ...

J-domain protein chaperone circuits in proteostasis and disease

Paolo De Los Rios, Duccio Malinverni, Ruobing Zhang

The J-domain proteins (JDP) form the largest protein family among cellular chaperones. In cooperation with the Hsp70 chaperone system, these co-chaperones orchestrate a plethora of distinct functions, including those that help maintain cellular proteostasi ...

Fluorescent D-Amino Acids for Super-resolution Microscopy of the Bacterial Cell Wall

Suliana Manley, Luc Reymond, Ophélie Rutschmann, Willi Leopold Stepp, Juliette Griffie, Chen Zhang, Jiangtao Qiao, Faustine Ambroisine Charline Ryckebusch

Fluorescent D-amino acids (FDAAs) have previ-ously been developed to enable in situ highlighting of locations of bacterial cell wall growth. Most bacterial cells lie at the edge of the diffraction limit of visible light; thus, resolving the precise details ...

Live-seq enables temporal transcriptomic recording of single cells

Bart Deplancke, Vincent Roland Julien Gardeux, Riccardo Dainese, Orane Josiane Guillaume-Gentil, Wanze Chen, Pernille Yde Rainer, Magda Zachara, Wouter Saelens

Single-cell transcriptomics (scRNA-seq) has greatly advanced our ability to characterize cellular heterogeneity(1). However, scRNA-seq requires lysing cells, which impedes further molecular or functional analyses on the same cells. Here, we established Liv ...
