Early-life vitamin A treatment rescues neonatal infection-induced durably impaired tolerogenic properties of celiac lymph nodes

Gut -draining mesenteric and celiac lymph nodes (mLNs and celLNs) critically contribute to peripheral tolerance toward food and microbial antigens by supporting the de novo induction of regulatory T cells (Tregs). These tolerogenic properties of mLNs and c ...

A human omentum-specific mesothelial-like stromal population inhibits adipogenesis through IGFBP2 secretion

Bart Deplancke, Pernille Yde Rainer, Radiana Ferrero, Julie Marie Russeil, Magda Zachara, Daniel Alpern, Vincent Roland Julien Gardeux, Jörn Pezoldt, Guido Van Mierlo

Although several mouse and human adipose SVF cellular subpopulations have by now been identified, we still lack an understanding of the cellular and functional variability of adipose stem and progenitor cell (ASPC) populations across human fat depots. To a ...

System and method for single cell phenotypical profiling and deterministic nanoliter-droplet encapsulation and deterministic droplet consortia assemblies

Bart Deplancke, Johannes Julius Bues, Jörn Pezoldt

The present invention concerns a system for phenotypical profiling of at least one object and deterministic nanoliter-droplet encapsulation, comprising sample supplying means, buffer supplying means; a microfluidic chip comprising an encapsulation area or ...

Pseudomonas aeruginosa type IV pili actively induce mucus contraction to form biofilms in tissue-engineered human airways

Bart Deplancke, Lorenzo Anton-Louis Talà, Tamara Rossy, Alexandre Louis André Persat, Jörn Pezoldt

The opportunistic pathogen Pseudomonas aeruginosa causes antibiotic-recalcitrant pneumonia by forming biofilms in the respiratory tract. Despite extensive in vitro experimentation, how P. aeruginosa forms biofilms at the airway mucosa is unresolved. To inv ...

Systematic benchmarking of single-cell ATAC-sequencing protocols

Bart Deplancke, Jörn Pezoldt, Camille Lucie Germaine Lambert

Benchmarking of scATAC-seq protocols demonstrates the effects of data quality on downstream analyses. ...

Postnatal expansion of mesenteric lymph node stromal cells towards reticular and CD34(+) stromal cell subsets

Bart Deplancke, Julie Marie Russeil, Wanze Chen, Vincent Roland Julien Gardeux, Maria Litovchenko, Marjan Biocanin, Jörn Pezoldt, Guido Van Mierlo

Gut-draining mesenteric lymph nodes (LN) provide the framework to shape intestinal adaptive immune responses. Based on the transcriptional signatures established by our previous work, the composition and immunomodulatory function of LN stromal cells (SC) v ...

Deterministic scRNA-seq captures variation in intestinal crypt and organoid composition

Matthias Lütolf, Bart Deplancke, Saba Rezakhani, Esther Amstad, Riccardo Dainese, Julie Marie Russeil, Antonius Chrisnandy, Vincent Roland Julien Gardeux, Johannes Julius Bues, Marjan Biocanin, Rita Sarkis, Jörn Pezoldt

DisCo is a deterministic droplet microfluidics tool for single-cell analysis on low cell input samples, which is demonstrated to profile individual intestinal organoids and in vivo-derived small tissues. ...

Fibroblastic reticular cells mitigate acute GvHD via MHCII-dependent maintenance of regulatory T cells

Jörn Pezoldt

Acute graft versus host disease (aGvHD) is a life-threatening complication of allogeneic hematopoietic cell transplantation (allo-HCT) inflicted by alloreactive T cells primed in secondary lymphoid organs (SLOs) and subsequent damage to aGvHD target tissue ...

A leukemia-protective germline variant mediates chromatin module formation via transcription factor nucleation

Freddy Radtke, Ute Koch, Bart Deplancke, Riccardo Dainese, Julie Marie Russeil, Daniel Alpern, Vincent Roland Julien Gardeux, Maria Litovchenko, Gerard Llimos Aubach, Jörn Pezoldt, Judith Franziska Kribelbauer

Non-coding variants coordinate transcription factor (TF) binding and chromatin mark enrichment changes over regions spanning >100 kb. These molecularly coordinated regions are named "variable chromatin modules" (VCMs), providing a conceptual framework of h ...

Disparate temperature-dependent virus-host dynamics for SARS-CoV-2 and SARS-CoV in the human respiratory epithelium

Bastien Mangeat, Bart Deplancke, Julie Marie Russeil, Daniel Alpern, Vincent Roland Julien Gardeux, Elisa Cora, Jörn Pezoldt

Since its emergence in December 2019, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has spread globally and become a major public health burden. Despite its close phylogenetic relationship to SARS-CoV, SARS-CoV-2 exhibits increased human-to- ...

The microbiota is dispensable for the early stages of peripheral regulatory T cell induction within mesenteric lymph nodes

Jörn Pezoldt

Intestinal Foxp3(+) regulatory T cell (Treg) subsets are crucial players in tolerance to microbiota-derived and food-borne antigens, and compelling evidence suggests that the intestinal microbiota modulates their generation, functional specialization, and ...

Mesenteric Lymph Node Transplantation in Mice to Study Immune Responses of the Gastrointestinal Tract

Jörn Pezoldt

Mesenteric lymph nodes (mLNs) are sentinel sites of enteral immunosurveillance and immune homeostasis. Immune cells from the gastrointestinal tract (GIT) are constantly recruited to the mLNs in steady-state and under inflammatory conditions resulting in th ...

Selective Retrieval of Individual Cells from Microfluidic Arrays Combining Dielectrophoretic Force and Directed Hydrodynamic Flow

Bart Deplancke, Carlotta Guiducci, Kevin Keim, Pierre-Emmanuel Marie Thiriet, Gabriele Gambardella, Jörn Pezoldt

Hydrodynamic-based microfluidic platforms enable single-cell arraying and analysis over time. Despite the advantages of established microfluidic systems, long-term analysis and proliferation of cells selected in such devices require off-chip recovery of ce ...
