A review of novel research technology to explore the mystery of traditional Chinese medicine: Terahertz.

During the 2022 Annual National Terahertz Biophysics Conference, the hypothesis was proposed that bio frequency electromagnetic fields sensitive points, akin to acupuncture points, exist in the human body. This development has prompted numerous researchers to apply terahertz technology to the field of traditional Chinese medicine (TCM). In recent years, terahertz technology has achieved notable progress in the field of TCM, particularly concerning the meridian-collateral system.

Optimal transplantation strategy using human induced pluripotent stem cell-derived cardiomyocytes for acute myocardial infarction in nonhuman primates.

Cardiomyocytes derived from human induced pluripotent stem cells (hiPSC-CMs) have the potential to be a therapeutic option for myocardium restoration. However, hiPSC-CMs of varying maturation and transplantation routes exhibit different reactivity and therapeutic effects. We previously demonstrated that the saponin compound induces more mature hiPSC-CMs.

Single cell landscape of parietal epithelial cells in healthy and diseased states.

The biology and diversity of glomerular parietal epithelial cells (PECs) are important for understanding podocyte regeneration and crescent formation. Although protein markers have revealed the morphological heterogeneity of PECs, the molecular characteristics of PEC subpopulations remain largely unknown. Here, we performed a comprehensive analysis of PECs using single-cell RNA sequencing (scRNA-seq) data.

Scoparone suppresses mitophagy-mediated NLRP3 inflammasome activation in inflammatory diseases.

Recent evidence shows that targeting NLRP3 inflammasome activation is an important means to treat inflammasome-driven diseases. Scoparone, a natural compound isolated from the Chinese herb Artemisia capillaris Thunb, has anti-inflammatory activity. In this study we investigated the effect of scoparone on NLRP3 inflammasome activation in inflammatory diseases.

Mechanisms exploration of Angelicae Sinensis Radix and Ligusticum Chuanxiong Rhizoma herb-pair for liver fibrosis prevention based on network pharmacology and experimental pharmacologylogy.

Angelicae Sinensis Radix (Danggui) and Ligusticum Chuanxiong Rhizoma (Chuan Xiong) herb-pair (DC) have been frequently used in Traditional Chinese medicine (TCM) prescriptions for hundreds of years to prevent vascular diseases and alleviate pain. However, the mechanism of DC herb-pair in the prevention of liver fibrosis development was still unclear. In the present study, the effects and mechanisms of DC herb-pair on liver fibrosis were examined using network pharmacology and mouse fibrotic model.

Neutrophil depletion enhances the therapeutic effect of PD-1 antibody on glioma.

Tumor-infiltrating neutrophils (TINs), the predominant leukocytes in the tumor microenvironment, are important for cancer-related immunosuppression. Combinations of multiple immune checkpoint inhibitors can significantly improve outcomes in murine glioma models. Here, we investigated TIN levels in human glioma samples and tested the antitumor efficacy of neutrophil depletion alone or in combination with an anti-programmed death 1 (PD-1) antibody.

Aerosol Inhalation-mediated Delivery of an Adeno-associated Virus 5-expressed Antagonistic Interleukin-4 Mutant Ameliorates Experimental Murine Asthma.

Background: T helper 2 (Th2) lymphocytes and associated interleukin (IL) 4 and IL-13 play crucial roles in asthma pathogenesis. In this study, we explored an adeno-associated virus 5 (AAV5) based gene therapy by delivering truncated IL-4 protein to antagonize IL-4 receptor α chain and interrupt asthmatic signal pathway.

Results: A recombinant adeno-associated virus 5 (AAV5) vector harboring a truncated mouse IL-4 gene (AAV5-mIL-4ΔC22) was prepared.

Molecular cloning and heterologous expression of a new xylanase gene from Plectosphaerella cucumerina.

A gene encoding a new xylanase, named xynZG, was cloned by the genome-walking PCR method from the nematophagous fungus Plectosphaerella cucumerina. The genomic DNA sequence of xynZG contains a 780 bp open reading frame separated by two introns with the sizes of 50 and 46 bp. To our knowledge, this would be the first functional gene cloned from P.
