Liposomal dexamethasone formulations offer targeted delivery and enhanced efficacy in treating rheumatoid arthritis (RA). Dex@FA-ROS-Lips utilize folic acid targeting to accumulate in inflamed joints, reducing cartilage destruction and joint swelling while improving circulation time and bioavailability. hPG-Dex liposomes enhance regulatory T cells and increase IL-10 expression, leading to systemic tolerance and reduced arthritis progression. Polymerized stealth liposomes preferentially accumulate in inflamed joints, decreasing TNF-α and IL-1β levels, thus mitigating arthritis symptoms. DP-SAL liposomes target neutrophils via sialic acid modification, enhancing anti-inflammatory effects and drug accumulation in joints. Dex-Lips reduce paw swelling, TNF-α, and IL-1β levels, showing superior therapeutic efficacy and fewer side effects compared to free DEX. These liposomal formulations demonstrate significant potential in improving RA treatment by providing targeted delivery and sustained release of DEX. Future research should focus on optimizing particle size, exploring advanced targeting strategies, and addressing scalability and regulatory challenges. Additionally, combining liposomal DEX with other therapies could further enhance treatment outcomes. Overall, liposomal DEX represents a promising approach for effective and safe RA therapy.

Xenograft-bearing immunodeficient mice are susceptible to developing unwanted disorders primarily irrelevant to nature of the xenografted tumor; and if get involved with such disorders, they do not produce reliable results, inevitably confounding the research outputs. This article reviews clinical signs of common unwanted disorders in experimental immunodeficient mice, and how to examine and report them.

Single-cell sequencing revealed that the number and immune function of effector T cells in the livers of severe liver injury mice model were lower than those in the livers of dengue fever mice model with mild liver damage. This finding may be related to the disruption of Th17/Treg homeostasis and macrophage polarization caused by dengue virus infection.

We use various laboratory tests to prove the function of emodin between FLSs and STMs. At the same time, A collagen-induced arthritis mouse model was developed to investigate the therapeutic potential of emodin in rheumatoid arthritis using flow cytometry, micro-CT, and staining.

The macrophages were infected with mouse hepatitis virus (MHV). The transcriptome analysis showed the immediate up regulation of different expressed genes (DEGs) related to inflammation. DEGs related to M2 differential polarization showed up regulation at 24 hpi, the late term after viral infection. In addition, DEGs related to metabolism and histone modification, like Ezh2 were detected, which might correlate with the trained immunity of macrophages. The current in vitro viral infection study showed the key innated immunity character of macrophages, which suggested the replacement value of viral infection cells model, to reduce the animal usage in preclinical researches.

A summary of ISP mechanisms in inducing cardiac fibrosis.

Procedure for Surgical Internal Immobilization Modeling. After intraperitoneal anesthesia, the rat was placed on the operating table (A). In the lateral decubitus position, a longitudinal skin incision of approximately 3 cm was made along the inferior edge of the scapula, perpendicular to the spine of the scapula (B). After exposing the scapula and humerus (C), two small holes were made in the inferior angle of the scapula using a 23G needle (D). Two 2–0 sutures were then passed through the holes and around the humeral shaft, securing them tightly to fix the shoulder joint (E–H). All wounds were closed with interrupted 3–0 nylon sutures.

Unmet clinical need in chronic kidney disease and NAFLD. Inhibition of ASK1 improves inflammation and fibrosis. Animal models can mimic disease progression.

GSDMD-NT^ki/wt × Alb-cre^ki/wt mice showed severe liver damage and hepatocyte vacuolation. The expression of genes involved in the development of liver fibrosis was stronger in the livers of GSDMD-NT^ki/wtandAlb-cre^ki/wt mice. GSDMD-NT induces fibrosis by mediating lipid metabolism.

Previous studies have shown correlations between obesity, type 2 diabetes (T2D), and neurodegenerative diseases, including dementia. A wide range of illnesses can result in dementia, including Alzheimer's disease (AD). The disorders that fall under the general category of “dementia” are caused by abnormal alterations in the brain. To counteract their significant influence on public health, it is imperative to gain an in-depth understanding of the relationship between obesity, T2D, and cognitive deficits. We evaluate the cognitive impact of obesity and T2D induced by high-fat diet (HFD) in collaborative cross (CC) mice. Our findings have demonstrated differences in the assessed phenotypes between the different CC lines and the C57BL/6J reference line. These findings highlight the role the host's genetic background plays in determining the degree of obesity and T2D development, as well as how it affects different organ weights and cognitive deficiencies that could worsen into AD when faced with a HFD challenge.

The two approaches establish HFrEF models with comparable trends. The RVAP group shows impaired right ventricular function, while the RAP group exhibits more severe decreased compliance and fibrosis in left ventricle.

Mendelian randomization (MR) analysis assumptions for lipid profile and muscle atrophy. Findings of this MR analysis suggest that hyperlipidemia may affect muscle mass and lead to muscle atrophy, but has no significant effect on muscle strength. On the other hand, increased muscle mass may reduce the incidence of dyslipidemia.

Through mining public databases, up-regulated and down-regulated differential gene expression analysis on 70 patient samples was conducted. Through prognosis survival analysis and genetic variation analysis, SULF1 was identified as a core gene. Then, related biological mechanisms were explored by mining co-expressed genes. Finally, combined clinical diagnosis and treatment potential drugs were explored.

Hemodynamic measurements improve the quality and certainty of the data obtained

Using chronic social defeat stress cage apparatus, the model mice exhibited characteristic behaviors resembling depression, including a significant decrease in preference for sugar-water, a notable reduction in the time spent sniffing female urine, a prolonged delay in initiating feeding, a substantial decrease in total distance traveled, residence time, and entries into the central zone in open field test, a significant decrease in the time taken to become immobile in forced swimming test (FST), a considerable increase in immobility time and the number of instances of immobility in FST and tail suspension test. These aforementioned behavioral manifestations were found to be reversible through drug intervention.
