conclusions these results exhibited the immuno potentiator effects of mip-3beta plasmid when coadministrated with the hcv core dna vaccine. complimentary studies integrating mip-3beta as a genetic adjuvant in hcv-core-dna vaccination models are warranted. results mice covaccinated with mip-3beta elicited an enhanced th1 biased systemic immune response as evidenced by higher ifn-γ/il-4 and anti-...

Abstract NAD +-boosting via nicotinamide riboside (NR) confer anti-inflammatory effects. However, underlying mechanisms and therapeutic potential remain incompletely defined. Given +is a co-enzyme in oxidoreductive reactions, metabolomics analysis identified two major metabolites that were increased by NR: inosine Prostaglandin E2 (PGE2). Both PGE2 supplementation blunted IFNβ release, however ...

The effect of CC-chemokine receptor 7 (CCR7) and CC-chemokine ligand 19 (CCL19) on rheumatic mitral stenosis is unknown. This study aimed to explore the roles of CCR7 and CCL19 in rheumatic mitral stenosis by measuring the expression of CCR7 and CCL19 in human mitral valves from rheumatic mitral stenosis patients. Additionally, we examined their effects on human mitral valve interstitial cells ...

The chemokine receptor CCR7 drives leukocyte migration into and within lymph nodes (LNs). It is activated by chemokines CCL19 and CCL21, which are scavenged by the atypical chemokine receptor ACKR4. CCR7-dependent navigation is determined by the distribution of extracellular CCL19 and CCL21, which form concentration gradients at specific microanatomical locations. The mechanisms underpinning th...

Despite their widespread expression, the in vivo recruitment activities of CCL19 (EBV-induced molecule 1 ligand chemokine) and CXCL12 (stromal cell-derived factor 1) have not been established. Furthermore, although CXCL13 (B lymphocyte chemoattractant) has been shown to induce lymphoid neogenesis through induction of lymphotoxin (LT)alpha1beta2, it is unclear whether other homeostatic chemokine...

Chemokine and the chemokine receptor have a key role in the tumor progress. Here, we supposed that CCR7 might induce the invasion, migration, and epithelial-mesenchymal transition (EMT) process of breast cancer. In this research, human breast cancer MCF-7 and MDA-MB-231cells were treated with CCL19 and small-interfering RNA (CCR7 siRNA) for activation and inhibition of CCR7, respectively. Cell ...

c-Jun N-terminal kinase (JNK) is generally thought to be involved in inflammation, proliferation and apoptosis. However, functional role(s) of this molecule in dendritic cells (DCs) has not been well understood. CCR7 ligands, CCL19 and CCL21, induce not only chemotaxis but also endocytosis in mature DCs. In the present study, we examined the role of JNK for inducing chemotaxis and endocytosis i...

The chemokine receptor CCR7 and its ligands CCL19 and CCL21 play a crucial role for the homing of lymphocytes and dendritic cells to secondary lymphoid tissues. Nevertheless, how CCR7 senses the gradient of chemokines and how migration is terminated are poorly understood. In this study, we demonstrate that CCR7(-GFP) is endocytosed into early endosomes containing transferrin receptor upon CCL19...

BACKGROUND Chemokines such as MIP-3β/CCL19 are important factors in the mechanism of cell migration and pathogenesis of central nervous system (CNS) inflammatory reactions. The hypothesis of this study is that CCL19, also known as MIP-3β, is involved in the pathogenesis of inflammatory and non-inflammatory CNS diseases of dogs. Experiments were performed on cerebrospinal fluid (CSF) and serum s...

Chronic rhinosinusitis (CRS) is a heterogeneous disease, with varying immunological and histopathological features. The CC chemokine ligand 19 (CCL19) can stimulate T cells and antigen-presenting cells into secondary lymphoid node formation, as observed in allergic rhinitis, inflammatory bowel disease and other inflammatory disorders. The purpose of this study was to investigate the expression ...
