Diabetic osteoporosis (DOP) is a serious complication of diabetes mellitus. It is urgent to explore efficient clinical treatment strategies for DOP. It has been found that mesenchymal stem cell-derived extracellular vesicles (MSC-EVs), as an emerging cell-free therapy, show great potential in DOP treatment.

Atrial arrhythmias occur in 20-40% of patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and are associated with an increased risk of sustained ventricular arrhythmias and inappropriate implantable cardioverter-defibrillator shocks. The pathophysiology of atrial arrhythmias in ARVC remains unclear. Most cases of gene-positive ARVC are linked to pathogenic variants in the desmosomal gene plakophilin-2 (PKP2).

Objectives: To observe the effect of electroacupuncture (EA) on the expressions of high mobility group protein 1(HMGB1) and myeloid differentiation factor 88 (MyD88) in the small intestine and intestinal flora of obese rats, so as to explore the potential mechanism of EA to improve obesity in rats.

Methods: After 1 week of acclimatization, 10 rats were randomly selected from 50 Wistar male rats as the normal group, and the rest rats were fed with high-fat diet for 8 weeks to establish the obese model. The successfully modeling rats were randomly divided into model group, EA group and sham EA group, with 10 rats in each group.

Obesity, a widespread global health issue, is frequently linked to disrupted lipid metabolism, resulting in excessive accumulation of adipose tissue and associated health complications. Acupuncture, a traditional Chinese medical modality, has exhibited potential as a viable intervention for addressing obesity. The underlying mechanism proposed involves the stimulation of specific acupoints to exert a regulatory influence on hepatic function.

Volume electron microscopy encompasses a set of electron microscopy techniques that can be used to examine the ultrastructure of biological tissues and cells in three dimensions. Two block face techniques, focused ion beam scanning electron microscopy (FIB-SEM) and serial block face scanning electron microscopy (SBF-SEM) have often been used to study biological tissue samples. More recently, these techniques have been adapted to in vitro tissue culture samples.

In a previous study, heart xenografts from 10-gene-edited pigs transplanted into two human decedents did not show evidence of acute-onset cellular- or antibody-mediated rejection. Here, to better understand the detailed molecular landscape following xenotransplantation, we carried out bulk and single-cell transcriptomics, lipidomics, proteomics and metabolomics on blood samples obtained from the transplanted decedents every 6 h, as well as histological and transcriptomic tissue profiling. We observed substantial early immune responses in peripheral blood mononuclear cells and xenograft tissue obtained from decedent 1 (male), associated with downstream T cell and natural killer cell activity.

Colorectal cancer (CRC) is a significant health problem with elevated mortality rates, prompting intense exploration of its complex molecular mechanisms and innovative therapeutic avenues. Resveratrol (RSV), recognised for its anticancer effects through SIRT1 activation, is a promising candidate for CRC treatment. This study focuses on elucidating RSV's role in CRC progression, particularly its effect on autophagy-related apoptosis.

Glycolysis is a fundamental cellular process, yet its regulatory mechanisms remain incompletely understood. Here, we show that a subset of glucose transporter 1 (GLUT1/SLC2A1) co-endocytoses with platelet-derived growth factor (PDGF) receptor (PDGFR) upon PDGF-stimulation. Furthermore, multiple glycolytic enzymes localize to these endocytosed PDGFR/GLUT1-containing vesicles adjacent to mitochondria.

Article Synopsis
  • - Microsporidia are fungal pathogens that can cause severe infections in humans and are dependent on their host's resources for growth and reproduction.
  • - Using advanced 3D imaging techniques, researchers studied the development of the microsporidian species Encephalitozoon intestinalis within human cells, revealing how it assembles its infection organelle, the polar tube.
  • - The study found that E. intestinalis infection significantly alters the structure of host cell mitochondria, indicating a complex interaction between the parasite and host cell organelles during infection.

Objectives: To observe the effect of electroacupuncture (EA) in obese rats with insulin resistance (IR) through regulating intestinal silent information regulator 1 (SIRT1)/Toll-like receptor 4 (TLR4) signaling pathway, so as to explore the underlying mechanism of EA in improving obesity-induced IR.

Methods: A total of 40 Wistar rats were randomly divided into 4 groups, i.e.

Intracellular degradation of proteins and organelles by the autophagy-lysosome system is essential for cellular quality control and energy homeostasis. Besides degradation, endolysosomal organelles can fuse with the plasma membrane and contribute to unconventional secretion. Here, we identify a function for mammalian SKP1 in endolysosomes that is independent of its established role as an essential component of the family of SCF/CRL1 ubiquitin ligases.

Generation of virus-host protein-protein interactions (PPIs) maps may provide clues to uncover SARS-CoV-2-hijacked cellular processes. However, these PPIs maps were created by expressing each viral protein singularly, which does not reflect the life situation in which certain viral proteins synergistically interact with host proteins. Our results reveal the host-viral protein-protein interactome of SARS-CoV-2 NSP3, NSP4, and NSP6 expressed individually or in combination.

Article Synopsis
  • The intestinal microbiota aids the hatching of whipworm eggs in mice by promoting structural changes in the eggs, crucial for the lifecycle of the parasite Trichuris muris.
  • Advanced microscopy techniques revealed that bacteria trigger the breakdown of polar plugs on the egg shells, allowing larvae to exit, and this process is optimized with high bacterial density.
  • The research highlights a unique relationship where both bacteria and larval enzymes work together to facilitate hatching, showcasing the evolutionary adaptation of the parasite to thrive in the mammalian gut environment.

Recent advances in volume electron microscopy (vEM) allow unprecedented visualization of the electron-dense structures of cells, tissues and model organisms at nanometric resolution in three dimensions (3D). Light-based microscopy has been widely used for specific localization of proteins; however, it is restricted by the diffraction limit of light, and lacks the ability to identify underlying structures. Here, we describe a protocol for ultrastructural detection, in three dimensions, of a protein (Connexin 43) expressed in the intercalated disc region of adult murine heart.

Microsporidia are an early-diverging group of fungal pathogens that infect a wide range of hosts. Several microsporidian species infect humans, and infections can lead to fatal disease in immunocompromised individuals. As obligate intracellular parasites with highly reduced genomes, microsporidia are dependent on metabolites from their hosts for successful replication and development.

Background: The most common form of neuronal ceroid lipofuscinosis (NCL) is juvenile CLN3 disease (JNCL), a currently incurable neurodegenerative disorder caused by mutations in the CLN3 gene. Based on our previous work and on the premise that CLN3 affects the trafficking of the cation-independent mannose-6 phosphate receptor and its ligand NPC2, we hypothesised that dysfunction of CLN3 leads to the aberrant accumulation of cholesterol in the late endosomes/lysosomes (LE/Lys) of JNCL patients' brains.

Methods: An immunopurification strategy was used to isolate intact LE/Lys from frozen autopsy brain samples.

Article Synopsis
  • * Using advanced microscopy techniques, the research visualized the structural changes in the egg and larva during the hatching process, highlighting the role of bacteria in altering the egg's polar plugs.
  • * The findings suggest that whipworm larvae release chitinase to help degrade the plugs from inside the egg, indicating an evolutionary adaptation to thrive in the bacteria-rich environment of the mammalian gut.
