Chronic low-grade inflammation is regarded to an important signature of atherosclerosis (AS). Macrophage (Mψ) and related polarization have been demonstrated play a crucial role in the occurrence development AS inflammation. Butyrate, bioactive molecule produced by intestinal flora, has increasingly exhibit vital for regulating chronic metabolic diseases. However, effectiveness multiple anti-inflammation mechanisms butyrate on still need be further understood. ApoE −/− mice fed with high-fat...

Background: Neutrophils rapidly accumulate in large numbers at sites of tissue damage, exhibiting not only their well-known bactericidal capabilities but also playing crucial roles angiogenesis and repair. While exosomes derived from human umbilical cord mesenchymal stem cells (HucMSC-Exo) have emerged as a promising therapeutic tool, exact mechanisms action remain partly elusive. We hypothesize that HucMSC-Exo treatment may modulate neutrophil phenotypes, thereby significantly influencing...

The paramyxovirus parainfluenza virus 5 (PIV5) enters cells by fusion of the viral envelope with plasma membrane through concerted action (F) protein and receptor binding hemagglutinin-neuraminidase. F folds initially to form a trimeric metastable prefusion that is triggered undergo large-scale irreversible conformational changes postfusion conformation. It thought refolding couples energy released fusion. synthesized as precursor (F0) must be cleaved host protease biologically active...

Lung adenocarcinoma (AD) is a common variant of non-small cell lung cancer (NSCLC). Programmed death protein 1/programmed ligand 1 (PD1/PD-L1) are promising immunotherapy targets and its expression may be an important biomarker predicting clinical response. In this study, we evaluated PD-L1 in conjunction with clinicopathological characteristics outcomes resected adenocarcinoma.This study included 133 cases adenocarcinoma. rate was 16.5% at the mRNA level 13.5% level, kappa coefficient two...

Sustained suppression of VEGF is needed in many patients with neovascular age-related macular degeneration (NVAMD), and gene transfer a VEGF-neutralizing protein promising approach to achieve it. Initial clinical trials testing this have shown encouraging signals, but evidence robust transgene expression consistent antiangiogenic antipermeability activity has been lacking. In study, we demonstrate an anti-human antibody fragment (antiVEGFfab) after subretinal injection AAV8-antiVEGFfab....

Disturbances in immunoregulation may lead to both cancer and autoimmune diseases. Many therapeutic drugs for diseases also display anti-tumor efficacy. The Janus kinase/signal transducer activator of transcription signaling pathways are involved the secretion more than 50 distinct cytokines, which have critical roles inducing tumorigenesis. Thus, kinases become classical immunotherapeutic targets immune disease. More 70 kinase inhibitors been approved as immunomodulatory clinical use, 12...

Hepatitis B virus (HBV) DNA integration into the host cell genome is reportedly a major cause of liver cancer, and source hepatitis surface antigen (HBsAg). High HBsAg levels can alter immune responses which therefore contributes to progression HBV-related disease. However, what extent leads persistent circulating unclear. Here, we aimed determine if HBV associated with persistence in people exposed HBV. We established digital droplet quantitative inverse PCR (dd-qinvPCR) method quantify...

Hepatocellular carcinoma (HCC) is an aggressive form of liver cancer. Gamma Knife a minimally invasive treatment option for cancer, but it has limitations such as the potential cancer recurrence and metastasis. In contrast, Photodynamic Therapy (PDT) offers targeted approach, repeatability, immune regulation enhancement, facilitation systemic treatment. However, traditional PDT faces in treating deep-seated tumors, HCC. Copper cysteamine (Cu-Cy), novel photosensitizer activated directly by...

Clinical trials in patients with macular edema due to diabetic retinopathy or retinal vein occlusion (RVO) have shown that suppression of VEGF not only improves edema, but also reopens closed vessels, prevents progression vessel closure, and retinopathy. In this study, we show the molecular basis for those clinical observations. Increased levels mice cause plugging vessels leukocytes, hypoxia. Suppression reduces leukocyte plugging, causing reperfusion vessels. Activation VEGFR1 contributes...
