Nr4a1 and Nr4a3 redundantly control clonal deletion and contribute to an anergy-like transcriptome in auto-reactive thymocytes to impose tolerance in mice.

Nat Commun

January 2025

Division of Rheumatology, Rosalind Russell and Ephraim P. Engleman Arthritis Research Center, Department of Medicine, University of California, San Francisco, CA, 94143, USA.

The Nr4a nuclear hormone receptors are transcriptionally upregulated in response to antigen recognition by the T cell receptor (TCR) in the thymus and are implicated in clonal deletion, but the mechanisms by which they operate are not clear. Moreover, their role in central tolerance is obscured by redundancy among the Nr4a family members and by their reported functions in Treg generation and maintenance. Here we take advantage of competitive bone marrow chimeras and the OT-II/RIPmOVA model to show that Nr4a1 and Nr4a3 are essential for the upregulation of Bcl2l11/BIM and thymic clonal deletion by self-antigen.

Neutrophils were historically considered a homogenous population of cells with functions limited to innate immunity against external threats. However, with the rise of immunotherapy, recent works have shown that neutrophils are also important actors in immuno-oncology. In this context, neutrophils appear as a more heterogenous population of cells.

Division of Tumor Biology and Immunology, The Netherlands Cancer Institute, Amsterdam, The Netherlands; Department of Immunology, Leiden University Medical Center, Leiden, The Netherlands; Oncode Institute, Utrecht, The Netherlands. Electronic address:

Neutrophils are pivotal in orchestrating tumor-induced systemic inflammation and are increasingly recognized for their critical involvement in both the initiation and progression of cancer. A fundamental facet of neutrophil biology is their migratory capacity, which enables them to extravasate and infiltrate tumors in other tissues, where they carry out essential effector functions. Unraveling the intricate mechanisms of neutrophil motility and migration is crucial for comprehending immune responses and inflammatory processes, shedding light on their substantial contribution to cancer progression.

Background: Pancreatic ductal adenocarcinoma (PDAC) is mostly refractory to immunotherapy due to immunosuppression in the tumor microenvironment and cancer cell-intrinsic T cell tolerance mechanisms. PDAC is described as a "cold" tumor type with poor infiltration by T cells and factors leading to intratumoral T cell suppression have thus received less attention. Here, we identify a cancer cell-intrinsic mechanism that contributes to a T cell-resistant phenotype and describes potential combinatorial therapy.

Department of Anatomy, Physiology, & Cell Biology, School of Veterinary Medicine, and California National Primate Research Center, University of California, Davis, County Road 98 & Hutchison Drive, Davis, CA, USA.

Background: Late-stage human immunodeficiency virus (HIV) infection is typically characterized by low CD4 + T-cell count. We previously showed that profound changes in the monocyte turnover (MTO) rate in rhesus macaques infected by the simian immunodeficiency virus (SIV) outperforms declining CD4 + T-cell counts in predicting rapid health decline associated with progression to terminal disease. High MTO is associated with increased tissue macrophage death.

HIV-associated neurocognitive disorder (HAND) is a complication of chronic inflammation caused by HIV infection that impairs cognitive and motor functions. HAND can occur at any age, regardless of the duration of infection, even in people living with HIV (PLWH) whose blood viral load is controlled by antiretroviral therapy. The diagnosis of HAND requires a battery of neuropsychological tests, which is time-consuming and burdensome, limiting its effectiveness for screening PLWH.

Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.

Amelioration of a von Willebrand disease type 2B phenotype in vivo upon treatment with allele-selective siRNAs.

Blood Adv

Department of Internal Medicine, Division of Thrombosis and Hemostasis, Einthoven Laboratory for Vascular and Regenerative Medicine, Leiden University Medical Center, Leiden, The Netherlands.

Treatment options for the bleeding disorder von Willebrand disease type 2B (VWD2B) are insufficient and fail to address the negative effects of circulating mutant von Willebrand factor (VWF). The dominant-negative nature of VWD2B makes functionally defective VWF an interesting therapeutic target. Previous in vitro studies have demonstrated the feasibility of allele-selective silencing of mutant VWF using small interfering RNAs (siRNAs) targeting common single nucleotide polymorphisms (SNPs) in the human VWF gene, an approach that can be applied irrespective of the disease-causing VWF mutation.

Childhood and adolescent classic Hodgkin Lymphoma (cHL) has long been a model for how we balance improved outcomes with increased toxicities in pediatric cancer. The recognition that unacceptable short- and long-term toxicities come with increasing intensity of treatment has led to a decades-long attempt to better understand the patient-specific factors that dictate responses and outcomes. Targeted immunotherapy has emerged as a promising adjunct to cancer treatment; it has been shown to improve outcomes for poorly responding patients, to salvage relapsed disease, and more recently, to replace more toxic therapy modalities such as chemotherapy and radiation while maintaining excellent outcomes.
