Bioengineering functional organoid models across scales

The last two decades have seen the development of organoid models for many different tissues and organs. Organoids are three-dimensional organ-mimetics derived from stem or progenitor cells comprising various specialized cell types, resembling the architec ...

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

Jacques Fellay, Christian Axel Wandall Thorball, Alessandro Borghesi, Yu Zhang, Peng Zhang, Qian Zhang

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 . ...

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 ...

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 ...

Susceptibility to infection in early life: a growing role for human genetics

Jacques Fellay, Alessandro Borghesi

The unique vulnerability to infection of newborns and young infants is generally explained by a constellation of differences between early-life immune responses and immune responses at later ages, often referred to as neonatal immune immaturity. This devel ...

Exploring the potency of normal and pathological human thymic epithelial cells

Tiphaine Mélodie Chantal Arlabosse

Thymic epithelial cells (TECs) are organised in a unique 3D network that is critical for the development of efficient and self-tolerant T-cells. We report for the first time that the human thymus of all ages, even old and involuted, contains a significant ...

Deciphering the subcapsular epithelial cells in human fetal and postnatal thymus

Diane Sophie Elodie Hemon

Most papers related to thymus focus on the cortical and medullary epithelial cells whereas the subcapsular layer is ignored. In this thesis, we are providing new informations about the subcapsular thymic epithelial cells (TECs) by comparing them to cortica ...

NCoR1 restrains thymic negative selection by repressing Bim expression to spare thymocytes undergoing positive selection

Johan Auwerx, Shuo Zhang, Na Zhang, Hui Xiao, Ye Zheng

Thymocytes must pass both positive and negative selections to become mature T cells. Negative selection purges thymocytes whose T-cell receptors (TCR) exhibit high affinity to self-peptide MHC complexes (self pMHC) to avoid autoimmune diseases, while posit ...

The corepressor NCOR1 regulates the survival of single-positive thymocytes

Johan Auwerx

Nuclear receptor corepressor 1 (NCOR1) is a transcriptional regulator bridging repressive chromatin modifying enzymes with transcription factors. NCOR1 regulates many biological processes, however its role in T cells is not known. Here we show that Cd4-Cre ...

Ultrathin Alumina Membranes as Scaffold for Epithelial Cell Culture from the Intestine of Rainbow Trout

Philippe Renaud, Kristin Schirmer, Songmei Wu, Carolin Drieschner

Permeable membranes are indispensable for in vitro epithelial barrier models. However, currently available polymer-based membranes are low in porosity and relatively thick, resulting in a limited permeability and unrealistic culture conditions. In this stu ...
