The aim of this study was to evaluate macrophages repolarization from pro-inflammatory M1 to anti-inflammatory M2 phenotype upon transfection with microRNA-223 (miR-223) duplexes and miR-223 expressing plasmid DNA encapsulated in CD44-targeting hyaluronic acid-poly(ethyleneimine) (HA-PEI) nanoparticles (NPs). The HA-PEI/miR-223 NPs with spherical shape and an average diameter of 200 nm were eff...
background and aims: plants as medicines have always played a vital role in human life. tumor necrosis factor alpha (tnf)-α is one of the macrophage-derived inflammatory cytokine with pleotropic effects in the inflammation process. some studies have been demonstrated that some of the echinops species have anti-inflammatory activity. in fact, echinops lasilepis is introduced as one of the native...
Inoculation with viable, but not inactivated, Coxiella burnetii resulted in the increased expression of transferrin receptors (TfR) in the murine macrophage-like cell line J774A.1. This upregulation was evident in immunoblots as early as 6 h postinfection, with TfR levels continuing to increase through the first 24 h of infection. Fluorescent labeling revealed that TfR upregulation occurred thr...
Core-shell nanostructures with nonionic amphiphilic shells and ionic cores encapsulating gentamicin were designed for therapy against intracellular pathogens, including Salmonella and Listeria. Flow cytometry and confocal microscopy showed that their uptake into J774A.1 macrophages proceeded mainly by fluid-phase endocytosis and clathrin-mediated pathways. The nanostructures were nontoxic in vi...
A Cu(2+) ensemble polyfluorene derivative, poly[5,5'-(((9H-fluorene-9,9-diyl)bis(hexane-6,1-diyl))bis(oxy))diisophthalate] sodium salt (PFT), displays unprecedented selectivity for PPi (LOD = 2.26 ppb) in aqueous solution as well as in random urine samples at physiological pH vis-a-vis monitoring ALP activity. Furthermore, intracellular imaging of Cu(2+) and PPi in mouse macrophage (J774A.1) an...
The datasets reported herein provide information about microarray experiment of macrophage cell line J774A.1 infected with three different strains of Leptospira spp. Transcriptomic profiles were generated using Affymetrix® Mouse Gene 2.1 ST Array Strip. Data was normalized and statically process, p-value < 0.01, FDR < 0.05 and log2 fold change (± 2). The microarray raw data are available in Gen...
BACKGROUND Beside their health benefits, dietary omega 3 polyunsaturated fatty acids (n-3 PUFA) might impair host resistance to Mycobacterium tuberculosis (Mtb) by creating an immunosuppressive environment. We hypothesized that incorporation of n-3 PUFA suppresses activation of macrophage antimycobacterial responses and favors bacterial growth, in part, by modulating the IFNgamma-mediated signa...
The formation of extracellular traps (ETs) has recently been recognized as a novel defense mechanism in several types of innate immune cells. It has been suggested that these structures are toxic to microbes and contribute significantly to killing several pathogens. However, the role of ETs formed by macrophages (METs) in defense against microbes remains little known. In this study, we demonstr...
