Abstract
Cholesterol reduction by intracellular protozoan parasite Leishmania donovani (L. donovani), causative agent of leishmaniasis, impairs antigen presentation, pro-inflammatory cytokine secretion and host-protective membrane-receptor signaling in macrophages. Here, we studied the miRNA mediated regulation of cholesterol biosynthetic genes to understand the possible mechanism of L. donovani-induced cholesterol reduction and therapeutic importance of miRNAs in leishmaniasis. System-scale genome-wide microtranscriptome screening was performed to identify the miRNAs involved in the regulation of expression of key cholesterol biosynthesis regulatory genes through miRanda3.0. 11 miRNAs out of 2823, showing complementarity with cholesterol biosynthetic genes were finally selected for expression analysis. These selected miRNAs were differentially regulated in THP-1 derived macrophages and in primary human macrophages by L. donovani. Correlation of expression and target validation through luciferase assay suggested two key miRNAs, hsa-miR-1303 and hsa-miR-874-3p regulating the key genes hmgcr and hmgcs1 respectively. Inhibition of hsa-mir-1303 and hsa-miR-874-3p augmented the expression of targets and reduced the parasitemia in macrophages. This study will also provide the platform for the development of miRNA-based therapy against leishmaniasis.

Abstract
Macrophages play multiple roles in innate immunity including phagocytosing pathogens, modulating the inflammatory response, presenting antigens, and recruiting other immune cells. Tissue-resident macrophages (TRMs) adapt to the local microenvironment and can exhibit different immune responses upon encountering distinct pathogens. In this study, we generated induced macrophages (iMACs) derived from human pluripotent stem cells (hPSCs) to investigate the interactions between the macrophages and various human pathogens, including the hepatitis C virus (HCV), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and Streptococcus pneumoniae. iMACs can engulf all three pathogens. A comparison of the RNA-seq data of the iMACs encountering these pathogens revealed that the pathogens activated distinct gene networks related to viral response and inflammation in iMACs. Interestingly, in the presence of both HCV and host cells, iMACs upregulated different sets of genes involved in immune cell migration and chemotaxis. Finally, we constructed an image-based high-content analysis system consisting of iMACs, recombinant GFP-HCV, and hepatic cells to evaluate the effect of a chemical inhibitor on HCV infection. In summary, we developed a human cell-based in vitro model to study the macrophage response to human viral and bacterial infections; the results of the transcriptome analysis indicated that the iMACs were a useful resource for modeling pathogen-macrophage-tissue microenvironment interactions.

Vet Microbiol 2024; 288:109948. [PMID: 38113573 DOI: 10.1016/j.vetmic.2023.109948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 11/25/2023] [Accepted: 12/10/2023] [Indexed: 12/21/2023]
Abstract
Bovine viral diarrhea virus (BVDV) is prevalent worldwide and is an important pathogen that represents a serious threat to the development of the cattle industry by causing significant economic losses. Liver X receptors (LXRs) are members of the nuclear receptor superfamily and have become attractive therapeutic targets for cardiovascular disease. In the present study, we found that LXRs in both Madin-Darby bovine kidney (MDBK) cells and mice were associated with BVDV infection. GW3965, an agonist for LXRs, significantly inhibited BVDV RNA and protein levels in MDBK cells. In vivo studies in a mouse model also confirmed the inhibitory role of GW3965 in BVDV replication and the ameliorating effect of GW3965 on pathological injury to the duodenum. In vitro investigations of the potential mechanisms involved showed that GW3965 significantly inhibited BVDV-induced increases in cholesterol levels and viral internalization. Furthermore, the antiviral activity of GW3965 was significantly reduced following cholesterol replenishment, thus demonstrating that cholesterol was involved in the resistance of GW3965 to BVDV replication. Further studies indicated the role of ATP-binding cassette transporter A1 (ABCA1) and cholesterol-25-hydroxylase (CH25H) in the antiviral activity of GW3965. We also demonstrated the significant antiviral effect of 25hydroxycholesterol (25HC), a product of the catalysis of cholesterol by CH25H. In addition, the anti-BVDV effects of demethoxycurcumin (DMC), cyanidin-3-O-glucoside (C3G), and saikosaponin-A (SSA), three natural agonizts of LXRs, were also confirmed in both MDBK cells and mice. However, the antiviral activities of these agents were weakened by SR9243, a synthetic inhibitor of LXRs. For the first time, our research demonstrated that the activation of LXRs can exert significant anti-BVDV effects in MDBK cells and mice.

Abstract
BACKGROUND Macrophage scavenger receptor 1 gene (MSR1), is responsible for producing macrophage scavenger receptors. MSR1 is primarily located on the surfaces of various macrophage types and is known to exert a range of effects on the human body. These effects include influencing innate and adaptive immunological reactions, as well as contributing to the development of conditions such as atherosclerosis, dyslipidemia, liver and lung disease, and cancer. The unregulated assimilation of lipoproteins by MSR1 leads to the creation of macrophages rich in cholesterol that manifest as foam-like cells, ultimately contributing to dyslipidemia. This occurrence highlights the significance of MSR1 as a key player in the pathophysiology of dyslipidemia. AIM In this study, we aimed to estimate variation in lipid profile in acne vulgaris (AV) patients. Also, we aimed to investigate the role of MSR1 in lipid profile variation. SUBJECTS AND METHODS A case-control study consisting of 100 patients with AV and 104 healthy controls. Lipid profiles were assessed using normalized enzymatic processes and genotype analyses were performed by a polymerase chain reaction and standard Sanger sequencing. Predictions of variant effects were performed using in silico tools. RESULT Our results indicated that the levels of lipid profile were higher in patients with AV than in healthy patients. The two haplotypes that were most prevalent in the patients were TCAC (16.5%) and CAGG (15.47%), whereas the two haplotypes that were more prevalent in the controls were TAAC (16.43%) and CCAC (15.62%). IVS5.59 C > A and rs433235 A > G are in linkage disequilibrium. Additionally, rs433235 A > G has a significant linkage disequilibrium with rs3747531 C > G. In silico analysis, tools indicated that the rs433235 A > G variant was disease-causing. CONCLUSION Patients diagnosed with TCAC and CAGG exhibited a higher prevalence compared to healthy patients with TAAC and CCAC. The linkage disequilibrium between rs433235 A > G and IVS5.59 C > A has been established. Furthermore, there appears to be significant linkage disequilibrium between rs3747531 C > G and rs433235 A > G. These findings support the notion that genetic variations may play a critical role in the pathogenesis of these conditions.

Abstract
Nonalcoholic steatohepatitis (NASH) is the progressive form of nonalcoholic fatty liver disease (NAFLD), and the dysregulation of lipid metabolism and oxidative stress are the typical features. Subsequent dyslipidemia and oxygen radical production may render the formation of modified lipids. Macrophage scavenger receptor 1 (MSR1) is responsible for the uptake of modified lipoprotein and is one of the key molecules in atherosclerosis. However, the unrestricted uptake of modified lipoproteins by MSR1 and the formation of cholesterol-rich foamy macrophages also can be observed in NASH patients and mouse models. In this review, we highlight the dysregulation of lipid metabolism and oxidative stress in NASH, the alteration of MSR1 expression in physiological and pathological conditions, the formation of modified lipoproteins, and the role of MSR1 on macrophage foaming and NASH development and progression.
