Metabolism: a potential regulator of neutrophil fate.

Neutrophils are essential components of the innate immune system that defend against the invading pathogens, such as bacteria, viruses, and fungi, as well as having regulatory roles in various conditions, including tissue repair, cancer immunity, and inflammation modulation. The function of neutrophils is strongly related to their mode of cell death, as different types of cell death involve various cellular and molecular alterations. Apoptosis, a non-inflammatory and programmed type of cell death, is the most common in neutrophils, while other modes of cell death, including NETOsis, necrosis, necroptosis, autophagy, pyroptosis, and ferroptosis, have specific roles in neutrophil function regulation.

However, the use of β-blockers in the treatment of septic shock remains controversial.

A simple "mix-and-detection" method based on template-free amplification for sensitive measurement of human cellular FEN1.

Flap endonuclease 1 (FEN1) is a structure-specific nuclease that can specially identify and cleave 5' flap of branched duplex DNA, and it plays a critical role in DNA metabolic pathways and human diseases. Herein, we propose a simple "mix-and-detection" strategy for sensitive measurement of human cellular FEN1 on basis of template-free amplification. We design a dumbbell probe with 5' flap as a substrate of FEN1 and a NH-labeled 3' termini to prevent nonspecific amplification.

Causal role of immune cells in aplastic anemia: Mendelian randomization (MR) study.

Prior research has identified associations between immune cells and aplastic anaemia (AA); however, the causal relationships between them have not been conclusively established. A two-sample Mendelian randomisation analysis was conducted to investigate the causal link between 731 immune cell signatures and AA risk using publicly available genetic data. Four types of immune signatures, including relative cell, absolute cell (AC), median fluorescence intensities and morphological parameters, were considered sensitivity analyses were also performed to verify the robustness of the results and assess potential issues such as heterogeneity and horizontal pleiotropy.

Targeting Hippo/YAP in intrahepatic cholangiocarcinoma: Promising molecules in cancer therapy.

The tumorigenesis of intrahepatic cholangiocarcinoma (ICC) has been identified to be exceptionally involved in dysregulated Hippo/Yes-associated protein (YAP) signaling pathway (Hippo/YAP). Hippo/YAP functions as a master regulator engaged in a plethora of physiological and oncogenic processes as well. Therefore, the aberrant Hippo/YAP could serve as an Achilles' heel regarding the molecular therapeutic avenues for ICC patients.
