Alterations in circulating CCL4 levels have been implicated in coronary artery disease (CAD), but the causal relationship and underlying mechanisms remain unclear. This study aims to analyse the role of CCL4 and its receptor (CCR5) in CAD using Mendelian randomisation (MR) analysis, bulk RNA and single cell RNA sequencing (scRNA-seq). The MR analysis was used to determine the causal relationship between 91 circulating inflammatory proteins and CAD.

Article Synopsis
  • This study investigates the relationship between specific immune cells and the risk of aortic dissection (AD), focusing on how blood metabolites mediate this connection.
  • Through analyzing 731 immune cell types using Mendelian Randomization techniques, the researchers identified three immune cell types positively linked to AD and two negatively linked.
  • Key findings highlighted that metabolites like Benzoate, N-acetylproline, and Carnitine C5:1 play significant mediating roles between various immune cells and the risk of developing AD.

Article Synopsis
  • The study explores the role of Nogo-B in managing cholesterol levels, revealing that its deficiency can enhance both the uptake and excretion of cholesterol in the liver.
  • Researchers found that inhibiting Nogo-B activates key proteins and receptors, which helps lower cholesterol levels by improving cholesterol metabolism.
  • The findings suggest that targeting Nogo-B could be a potential strategy for reducing cholesterol and atherosclerotic plaques in the body.

Glucagon-like peptide 1 (GLP1), which is mainly processed and cleaved from proglucagon in enteroendocrine cells (EECs) of the intestinal tract, acts on the GLP1 receptor in pancreatic cells to stimulate insulin secretion and to inhibit glucagon secretion. However, GLP1 processing is not fully understood. Here, we show that reticulon 4B (Nogo-B), an endoplasmic reticulum (ER)-resident protein, interacts with the major proglucagon fragment of proglucagon to retain proglucagon on the ER, thereby inhibiting PCSK1-mediated cleavage of proglucagon in the Golgi.

High fructose intake during pregnancy increases insulin resistance (IR) and gestational diabetes mellitus (GDM) risk. IR during pregnancy primarily results from elevated hormone levels. We aim to determine the role of liver carbohydrate response element binding protein (ChREBP) in insulin sensitivity and lipid metabolism in pregnant mice and their offspring.

Pickering emulsion has great potential as a vaccine adjuvant due to its unique advantages such as its high antigen loading efficiency, great stability, etc. Among several adjuvants on the market, aluminum adjuvant (Alum) is the most widely used at present. However, problems such as the inability to effectively induce cellular immunity and the poor effect on subunit vaccines limit the application of Alum.

Modern medical science believes that astragalus polysaccharides (APS) have the efficacy of strengthening immune system, while their peculiarities greatly reduced clinical applications. Poly(lactic-co-glycolic acid) (PLGA) is a synthetic carrier material with outstanding biochemical properties. In this study, PLGA materials were used to prepare the novel pH-responsive targeting drug delivery carriers which were encapsulated APS inside.

In many clinical studies, prebiotics have been used as adjuvant therapy for inflammatory bowel disease (IBD). Phellinus igniarius polysaccharide (PIP) possesses great anti-inflammatory and prebiotic activities. Herein, we developed an orally deliverable PIP-loaded chitosan-modified PLGA nanomedicine (CS-PIPP) to investigate its anti-inflammatory effect in vitro and in vivo.

The aim of this study was to identify miRNAs in plasma exosomes as noninvasive biomarkers for the early diagnosis of lung adenocarcinoma (LUAD). First, exosomal miRNA profiling of three patients with early LUAD and three patients with benign lung disease were screened by next-generation sequencing (NGS) method. Sequencing results showed that 154 exosomal miRNAs were differentially expressed in the plasma of LUAD patients, among which 68 miRNAs were up-regulated and 86 miRNAs were down-regulated.

The Chinese yam polysaccharides PLGA nanoparticles were applied as stabilizers in this study to prepare O/W Pickering emulsion. The optimized preparation conditions were PLGA concentration of 5 mg/mL, ultrasonic power of 50 %, and ultrasonic time of 2 min. The CYP-PPAS emulsion exhibits a raspberry-like morphology with a large number of nanoparticles surrounding the oil droplets.

polysaccharide (RMP), one of the most important active components of , has been attracting increasing interest because of its potent bioactive properties, including anti-inflammatory, antitumor, and antidiabetic effects. Despite the great therapeutic potential of RMP, its inherent properties of low bioavailability and brief biological half-life have limited its applications to the clinic. Thus, RMP was packaged by poly(lactic--glycolic acid) (PLGA) nanoparticles to develop a novel anti-inflammatory nanomedicine (PLGA-RMP) in this study.

N-methyladenosine (mA) RNA modification is the most abundant modification method in mRNA, and it plays an important role in the occurrence and development of many cancers. This paper mainly discusses the role of mA RNA methylation regulators in lung adenocarcinoma (LUAD) to identify novel prognostic biomarkers. The gene expression data of 19 mA methylation regulators in LUAD patients and its relevant clinical parameters were extracted from The Cancer Genome Atlas (TCGA) database.

Cyclophosphamide (CY), extensively used as an anti-cancer agent, could cause diverse side effects, such as immunosuppression and intestinal barrier damage. Alhagi honey polysaccharides (AH), polysaccharides isolated from Alhagi honey, are widely known for their anti-tumor and immunomodulatory activities. Herein, AH are evaluated for their ability to protect mice from CY-induced toxicity.
