MHC-independent αβT cells: Lessons learned about thymic selection and MHC-restriction

Frontiers in Immunology, 2022
Understanding the generation of an MHC-restricted T cell repertoire is the cornerstone of modern T cell immunology. The unique ability of αβT cells to only recognize peptide antigens presented by MHC molecules but not conformational antigens is referred ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Identifying proteins bound to native mitotic ESC chromosomes reveals chromatin repressors are important for compaction

Nature Communications, 2020
Epigenetic information is transmitted from mother to daughter cells through mitosis. Here, the authors isolate native chromosomes from metaphase-arrested cells and perform LC-MS/MS to identify chromosome-bound proteins in pluripotent stem cells during ...

Polypyrimidine tract-binding proteins are essential for B cell development

eLife, 2020
Polypyrimidine tract-binding protein 1 (PTBP1) is a RNA-binding protein (RBP) expressed throughout B cell development. Deletion of Ptbp1 in mouse pro-B cells results in upregulation of PTBP2 and normal B cell development.

Epigenetic changes induced by in utero dietary challenge result in phenotypic variability in successive generations of mice

Nature Communications, 2022
Here the authors show that a high-fat diet in pregnant mice can release silencing of the imprinted Dlk1 locus in multiple generations of offspring.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Dynamic reorganisation of intermediate filaments coordinates early B-cell activation

Life Science Alliance, 2018
This study examines the role of vimentin, a type III intermediate filament, in B-cell function using a combination of in vitro and in vivo assays, including super-resolution microscopic techniques.

New Insights into Epigenetic Regulation of T Cell Differentiation

Cells, 2021
Immature CD4− CD8− thymocytes progress through several developmental steps in the thymus, ultimately emerging as mature CD4+ (helper) or CD8+ (cytotoxic) T cells.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Bone marrow monocytes sustain NK cell-poiesis during non-alcoholic steatohepatitis

Cell Reports
Summary: Natural killer (NK) cells are the predominant lymphocyte population in the liver. At the onset of non-alcoholic steatohepatitis (NASH), an accumulation of activated NK cells is observed in the liver in parallel with inflammatory monocyte ...
