An anti-CD19-exosome delivery system navigates the blood-brain barrier for targeting of central nervous system lymphoma.

Background: High-dose methotrexate (HD-MTX) serves as the cornerstone of central nervous system lymphoma (CNSL) treatment, but its efficacy is limited due to low blood-brain barrier (BBB) penetration and adverse effects. This study is focused on an exosome-based drug delivery approach aimed at enhancing BBB permeability, thereby reducing the required dosage of methotrexate (MTX) while ensuring specific targeting of CNSL.

Methods: Human adipose-derived mesenchymal stem cells (hAMSCs) were modified with a lentiviral vector encoding anti-CD19, incorporated into exosomes characterized by colloidal gold immunoelectron microscopy and Nano flow cytometry.

This study aimed to explore whether SP70 targeted tumor cell isolation technology with immunomagnetic beads can improve the accuracy of cytopathological examination.

Light-eye-body axis: exploring the network from retinal illumination to systemic regulation.

The human body is an intricate system, where diverse and complex signaling among different organs sustains physiological activities. The eye, as a primary organ for information acquisition, not only plays a crucial role in visual perception but also, as increasing evidence suggests, exerts a broad influence on the entire body through complex circuits upon receiving light signals which is called non-image-forming vision. However, the extent and mechanisms of light's impact on the body through the eyes remain insufficiently explored.

A HPLC-assisted mathematical prediction method of ternary solvent systems to develop an intelligent online selection system for countercurrent chromatography solvent system.

Countercurrent chromatography (CCC) is an efficient technique for purifying bioactive natural compounds, but selecting the solvent system can be a time-consuming and crucial process for successful separation. This paper discussed the HPLC-assisted mathematical prediction method for the n-hexane/alcohol solvents/water (HAWat) and ethyl acetate/n-butanol/water (EBuWat) systems and designed an intelligent online selection system to simplify the separation process. First, the applicable rage of HAWat and EBuWat solvent systems were quantified by the methanol concentration at the column inlet when template molecules peak in a HPLC analysis (B%).

Interleukin 15 (IL15) is crucial for fostering the survival and proliferation of nature killer (NK) cells and cytotoxic T lymphocytes (CTLs), playing a pivotal role in tumor control. However, IL15 supplementary therapy encounters challenges such as systemic inflammation and non-specific stimulation of cancer cells. Herein, a nanovesicle termed DoxFILN, comprising a membrane presenting IL15/IL15 receptor α complexes (IL15c) and a core of doxorubicin-loaded ferritin (Dox-Fn) are reported.

Conformation Influences Biological Fates of Peptide-Based Nanofilaments by Modulating Protein Adsorption and Interfilament Entanglement.

Filamentous structures exert biological functions mediated by multivalent interactions with their counterparts in sharp contrast with spherical ones. The physicochemical properties and unique behaviors of nanofilaments that are associated with multivalent interaction with protein are poorly understood. Here, peptide-based nanofilaments containing different homotetrapeptidic inserts are reported and their protein adsorption and biological fates are tested.

Effect of Addition Amount of Ethylenediamine on Interlayer Nanochannels and the Separation Performance of Graphene Oxide Membranes.

In recent years, graphene oxide (GO)-based two-dimensional (2D) laminar membranes have attracted considerable attention because of their unique well-defined nanochannels and deliver a wide range of molecular separation properties and fundamentals. However, the practical application of 2D GO layered membranes suffers from instability in aqueous solutions as the interlayer -spacing of GO membranes is prone to expansion caused by the hydration effect. In this study, the effects of the ethylenediamine (EDA) addition amount on the structure, crosslinking mechanism and separation performance of GO membranes were investigated systematically, and membrane performance was evaluated using water permeability and dye/salt rejection tests.

Hepatitis B Virus X Protein Contributes to Hepatocellular Carcinoma via Upregulation of KIAA1429 Methyltransferase and mRNA m6A Hypermethylation of HSPG2/Perlecan.

Chronic hepatitis B virus (HBV) remains to be the most common risk factor of hepatocellular carcinoma (HCC). While previous work has primarily focussed on understanding the direct and indirect mechanisms of Hepatitis B virus X protein (HBx)-mediated hepatocarcinogenesis, from genetic and epigenetic perspectives, its influence on RNA modification mediated onset of liver malignancies is less well understood. This study explored the role of HBV-encoded HBx in altering the m6A methylome profile and its implications on the pathogenesis of HCC.
