3D imaging and pathological analysis of microglia in LPS-treated mice with light-sheet fluorescence microscopy.

Although two-dimensional (2D) histology and immunohistochemistry techniques have long been established and successfully applied to obtain structural information from tissues, recent advances in tissue clearing and expansion approaches combined with light sheet microscopy have led to the realization of three-dimensional (3D) nondestructive pathology, which may revolutionize our knowledge of the morphology of an organ or the whole body in its true state. Employing these 3D technologies, we obtained imaging data of microglia in whole hippocampus of mice. We established a simple procedure to analyze the 3D structures of microglia using the commercial software Amira.

Augmented immunogenicity of the HPV16 DNA vaccine via dual adjuvant approach: integration of CpG ODN into plasmid backbone and co-administration with IL-28B gene adjuvant.

Therapeutic human papillomavirus (HPV) DNA vaccine is an attractive option to control existed HPV infection and related lesions. The two early viral oncoproteins, E6 and E7, are continuously expressed in most HPV-related pre- and cancerous cells, and are ideal targets for therapeutic vaccines. We have previously developed an HPV 16 DNA vaccine encoding a modified E7/HSP70 (mE7/HSP70) fusion protein, which demonstrated significant antitumor effects in murine models.

Posttranscriptional Control of Neural Progenitors Temporal Dynamics During Neocortical Development by Syncrip.

The development of the mammalian neocortex is precisely regulated by temporal gene expression, yet the temporal regulatory mechanisms of cortical neurogenesis, particularly how radial glial cells (RGCs) sequentially generate deep to superficial neurons, remain unclear. Here, the hnRNP family member Syncrip (hnRNP Q) is identified as a key modulator of superficial neuronal differentiation in neocortical neurogenesis. Syncrip knockout in RGCs disrupts differentiation and abnormal neuronal localization, ultimately resulting in superficial cortical layer defects as well as learning and memory impairments in mice.

The de novo synthesis of GABA and its gene regulatory function control hepatocellular carcinoma metastasis.

The neurotransmitter gamma-aminobutyric acid (GABA) has been thought to be involved in the development of some types of cancer. Yet, the de novo synthesis of GABA and how it functions in hepatocellular carcinoma (HCC) remain unclear. Here, we report that SLC6A12 acts as a transporter of GABA, and that aldehyde dehydrogenase 9 family member A1 (ALDH9A1), not glutamate decarboxylase 1 (GAD1), generates GABA in human HCC.

Clozapine and rapamycin reverse behavioral abnormalities in an animal model of autoimmune schizophrenia.

Objective: Autoantibody-associated psychosis represents a distinct disease subgroup of patients with schizophrenia with a suspected autoimmune origin. Although preliminary studies have suggested adjunctive drug treatment strategies targeting the immune system, further validation of these findings is warranted. Autoantibodies against SFT2D2 have been identified in patients with schizophrenia.

Molecular intersections of traumatic brain injury and Alzheimer's disease: the role of ADMSC-derived exosomes and hub genes in microglial polarization.

Traumatic brain injury (TBI) is a significant contributor to global mortality and morbidity, with emerging evidence indicating a heightened risk of developing Alzheimer's disease (AD) following TBI. This study aimed to explore the molecular intersections between TBI and AD, focusing on the role of adipose mesenchymal stem cell (ADMSC)-derived exosomes and hub genes involved in microglial polarization. Transcriptome profiles from TBI (GSE58485) and AD (GSE74614) datasets were analyzed to identify differentially expressed genes (DEGs).

Second-line systemic treatment for metastatic colorectal cancer: A systematic review and Bayesian network meta-analysis based on RCT.

Background: The optimal second-line systemic treatment for metastatic colorectal cancer (mCRC) is inconclusive.

Methods: We searched PubMed, Web of Science, EMBASE, and Cochrane Library for RCTs comparing second-line systemic treatments for mCRC from the inception of each database up to February 3, 2024. Markov Chain Monte Carlo (MCMC) technique was used in this network meta-analysis (NMA) to generate the direct and indirect comparison results among multiple treatments in progression-free survival (PFS), overall response rate (ORR), overall survival (OS), complete response (CR), partial response (PR), grade 3 and above adverse events (Grade ≥ 3AE), and any adverse events (Any AE).
