Loss of anticancer NK cell function in AML patients is associated with fatal disease progression and remains poorly understood. Here, we demonstrate that AML-blasts isolated from patients rapidly inhibit NK cell function and escape NK cell-mediated killing. Transcriptome analysis of NK cells exposed to AML-blasts revealed increased CREM expression and transcriptional activity, indicating enhanced cAMP signalling, confirmed by uniform production of the cAMP-inducing prostanoid PGE2 by all AML-blast isolates from patients.

Enforced CARD11/MALT1 signaling in dendritic cells triggers hemophagocytic lymphohistiocytosis.

Proc Natl Acad Sci U S A

December 2024

Institute of Clinical Chemistry and Pathobiochemistry, School of Medicine and Health, Technical University of Munich, Munich 81675, Germany.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome fueled by uncontrolled mononuclear phagocyte activity, yet the innate immune mechanisms driving HLH pathogenesis remain elusive. Germline gain-of-function (GOF) mutations in CARD11, a pivotal regulator of lymphocyte antigen receptor signaling, cause the lymphoproliferative disease B-cell expansion with NF-κB and T-cell anergy, which is frequently associated with HLH development. Given that CARD11 is physiologically expressed not only in lymphocytes but also in dendritic cells (DCs), we explored whether enforced CARD11 signaling in DCs contributes to immunopathology.

Design of optimal concentrations for in vitro cytotoxicity experiments.

Arch Toxicol

January 2025

Department of Statistics, TU Dortmund University, Vogelpothsweg 87, Dortmund, 44227, North Rhine-Westphalia, Germany.

Concentration-dependent cytotoxicity experiments are frequently used in toxicology. Although it has been reported that an adequate choice of concentrations improves the quality of the statistical inference substantially, a recent literature review of three major toxicological journals has shown that the corresponding methods are rarely used in toxicological practice. In this study the performance of different sets of concentrations, also called designs, are analyzed, while the overall goal is to promote the advantages of optimal design procedures and to present a user-friendly guideline for planning new cytotoxicity concentration-response experiments.

Radiotherapy, which is commonly used for the local control of thoracic cancers, also induces chronic inflammatory responses in the microvasculature of surrounding normal tissues such as the lung and heart that contribute to fatal radiation-induced lung diseases (RILDs) such as pneumonitis and fibrosis. In this study, we investigated the potential of cannabidiol (CBD) to attenuate the irradiation damage to the vasculature. We investigated the ability of CBD to protect a murine endothelial cell (EC) line (H5V) and primary lung ECs isolated from C57BL/6 mice from irradiation-induced damage in vitro and lung ECs (luECs) in vivo, by measuring the induction of oxidative stress, DNA damage, apoptosis (in vitro), and induction of inflammatory and pro-angiogenic markers (in vivo).
