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

Jörn Pezoldt

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 ...

Autoantibodies against type I IFNs in humans with alternative NF-κB pathway deficiency

Jacques Fellay, Christian Axel Wandall Thorball, Alessandro Borghesi

Patients with autoimmune polyendocrinopathy syndrome type 1 (APS-1) caused by autosomal recessive AIRE deficiency produce autoantibodies that neutralize type I interferons (IFNs) 1,2 , conferring a predisposition to life-threatening COVID-19 pneumonia 3 . ...

Reaching an understanding of cortico-medullary control of forelimb behaviors

Mackenzie Mathis, Thomas Trevelyan James Sainsbury

How the neocortex modulates hindbrain and spinal circuits is of fundamental interest for understanding mo-tor control and adaptive behaviors. New work from Yang, Kanodia, and Arber demonstrates that there is an exquisite anatomical organization and functio ...

Stromal Notch ligands foster lymphopenia-driven functional plasticity and homeostatic proliferation of naive B cells

Freddy Radtke, Ute Koch

In lymphopenic environments, secondary lymphoid organs regulate the size of B and T cell compartments by supporting the homeostatic proliferation of mature lymphocytes. The molecular mechanisms underlying these responses and their functional consequences r ...

Microfluidic T Cell Selection by Cellular Avidity

Li Tang, Alexandre Harari, Armand Kurum

No T cell receptor (TCR) T cell therapies have obtained clinical approval. The lack of strategies capable of selecting and recovering potent T cell candidates may be a contributor to this. Existing protocols for selecting TCR T cell clones for cell therapi ...

Notch1-driven T-ALL chromatin landscape is regulated by Tcf1 in hematopoietic progenitors

Mateusz Waldemar Antoszewski

Notch1 receptor signaling is essential for T cell fate specification and physiological thymic T lymphocyte development. Its dysregulation and oncogenic activation are detected in almost 80% of pediatric patients suffering from T cell acute lymphoblastic le ...

Follicular regulatory helper T cells control the response of regulatory B cells to a high-cholesterol diet

Nikolaos Stergiopoulos

Aims B cell functions in the process of atherogenesis have been investigated but several aspects remain to be clarified. ...

Systematic screening of viral and human genetic variation identifies antiretroviral resistance and immune escape link

Jacques Fellay, Christian Axel Wandall Thorball

Background: Considering the remaining threat of drug-resistantmutations (DRMs) to antiretroviral treatment (ART) efficacy, we investigated how the selective pressure of human leukocyte antigen (HLA)-restricted cytotoxic T lymphocytes drives certain DRMs' e ...

Single-cell lipidomics reveals a role for cell-to-cell sphingolipid heterogeneity in fibroblast activation

Laura Capolupo

Cell-to-cell variability plays a key role in tissue patterning by setting initial asymmetry that primes cell fate decisions. Fluctuations in the activity of regulatory molecules can commit individual cells to divergent differentiation pathways, and cell-to ...

Regulatory T cells engineered with TCR signaling-responsive IL-2 nanogels suppress alloimmunity in sites of antigen encounter

Li Tang, Na Li

Adoptive cell transfer of ex vivo expanded regulatory T cells (T-r(egs)) has shown immense potential in animal models of auto- and alloimmunity. However, the effective translation of such T-reg therapies to the clinic has been slow. Because T-reg homeostas ...

Canonical Notch signaling controls the early thymic epithelial progenitor cell state and emergence of the medullary epithelia lineage in fetal thymus development

Freddy Radtke, Ute Koch, Dong Liu

Thymus function depends on the epithelial compartment of the thymic stroma. Cortical thymic epithelial cells (cTECs) regulate T cell lineage commitment and positive selection, while medullary (m) TECs impose central tolerance on the T cell repertoire. Duri ...

In Vivo Pre-Instructed HSCs Robustly Execute Asymmetric Cell Divisions In Vitro

Matthias Lütolf, Mukul Girotra, Aline Roch, Vincent Trachsel

Hematopoietic stem cells (HSCs) are responsible for life-long production of all mature blood cells. Under homeostasis, HSCs in their native bone marrow niches are believed to undergo asymmetric cell divisions (ACDs), with one daughter cell maintaining HSC ...

CD36-mediated metabolic adaptation supports regulatory T cell survival and function in tumors

Etienne Meylan

Depleting regulatory T cells (T-reg cells) to counteract immunosuppressive features of the tumor microenvironment (TME) is an attractive strategy for cancer treatment; however, autoimmunity due to systemic impairment of their suppressive function limits it ...

PEG/HA Hybrid Hydrogels for Biologically and Mechanically Tailorable Bone Marrow Organoids

Nicolas Antoine Vincent Broguiere, Queralt Vallmajó Martín

Bone marrow (BM) organoids provide powerful tools to study the vital interplay between the BM microenvironment and resident cells. Current biomaterials, however, are limited in terms of versatility for independently studying the biochemical and biophysical ...

Synthetically glycosylated antigens induce antigen-specific tolerance and prevent the onset of diabetes

Jeffrey Alan Hubbell, David Scott Wilson, Sachiko Hirosue, Martina Damo, Giacomo Olimpio Diaceri

Homeostatic antigen presentation by hepatic antigen-presenting cells, which results in tolerogenic T-cell education, could be exploited to induce antigen-specific immunological tolerance. Here we show that antigens modified with polymeric forms of either N ...

Microfluidic device performing on flow study of serial cell–cell interactions of two cell populations

Philippe Renaud, George Coukos, Alexandre Harari, Thamani Dahoun, Margaux Catherine Marie Duchamp, Clarisse Jeanne Antonia Benoit

In this study we present a novel microfluidic hydrodynamic trapping device to probe the cell–cell interaction between all cell samples of two distinct populations. We have exploited an hydrodynamic trapping method using microfluidics to immobilize a batch ...

New roles of the lymphatic endothelium in modulating adaptive immunity: implications for immune tolerance and cancer immunotherapy

Lambert Charles François Potin

Lymphatic vessels have traditionally been considered as passive conduits for interstitial fluid drainage and for immune cell trafficking to lymph nodes. In the last two decades, many studies have challenged this classical dogma: lymphatic endothelial cells ...
