Abstract
Toll-like receptors (TLRs) are a family of pattern recognition receptors (PRRs) that can identify pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). TLRs play an important role in the innate immune response, leading to acute and chronic inflammation. Cardiac hypertrophy, an important cardiac remodeling phenotype during cardiovascular disease, contributes to the development of heart failure. In previous decades, many studies have reported that TLR-mediated inflammation was involved in the induction of myocardium hypertrophic remodeling, suggesting that targeting TLR signaling might be an effective strategy against pathological cardiac hypertrophy. Thus, it is necessary to study the mechanisms underlying TLR functions in cardiac hypertrophy. In this review, we summarized key findings of TLR signaling in cardiac hypertrophy.

Abstract
Immunotherapies for cancers may cause severe and life-threatening cardiotoxicities. The underlying mechanisms are complex and largely elusive. Currently, there are several ongoing clinical trials based on the use of activated invariant natural killer T (iNKT) cells. The potential cardiotoxicity commonly associated with this particular immunotherapy has yet been carefully evaluated. The present study aims to determine the effect of activated iNKT cells on normal and β-adrenergic agonist (isoproterenol, ISO)-stimulated hearts. Mice were treated with iNKT stimulants, α-galactosylceramide (αGC) or its analog OCH, respectively, to determine their effect on ISO-induced cardiac injury. We showed that administration of αGC (activating both T helper type 1 (Th1)- and T helper type 2 (Th2)-liked iNKT cells) significantly accelerated the progressive cardiac injury, leading to enhanced cardiac hypertrophy and cardiac fibrosis with prominent increases in collagen deposition and TGF-β1, IL-6, and alpha smooth muscle actin expression. In contrast to αGC, OCH (mainly activating Th2-liked iNKT cells) significantly attenuated the progression of cardiac injury and cardiac inflammation induced by repeated infusion of ISO. Flow cytometry analysis revealed that αGC promoted inflammatory macrophage infiltration in the heart, while OCH was able to restrain the infiltration. In vitro coculture of αGC- or OCH-pretreated primary peritoneal macrophages with primary cardiac fibroblasts confirmed the profibrotic effect of αGC and the antifibrotic effect of OCH. Our results demonstrate that activating both Th1- and Th2-liked iNKT cells is cardiotoxic, while activating Th2-liked iNKT cells is likely cardiac protective, which has implied key differences among subpopulations of iNKT cells in their response to cardiac pathological stimulation.

Abstract
Accumulation of lipofuscin in the retinal pigment epithelium (RPE) is considered a major cause of RPE dysfunction and senescence in age-related macular degeneration (AMD), and N-retinylidene-N-retinylethanolamine (A2E) is the main fluorophore identified in lipofuscin from aged human eyes. Here, human-induced pluripotent stem cell (iPSC)-RPE was generated from healthy individuals to reveal proteomic changes associated with A2E-related RPE cell senescence. A novel RPE cell senescence-related protein, high-mobility group box 1 (HMGB1), was identified based on proteomic mass spectrometry measurements on iPSC-RPE with A2E treatment. Furthermore, HMGB1 upregulated Caveolin-1, which also was related RPE cell senescence. To investigate whether changes in HMGB1 and Caveolin-1 expression under A2E exposure contribute to RPE cell senescence, human ARPE-19 cells were stimulated with A2E; expression of HMGB1, Caveolin-1, tight junction proteins and senescent phenotypes were verified. HMGB1 inhibition alleviated A2E induced cell senescence. Migration of RPE cells was evaluated. Notably, A2E less than or equal to 10μM induced both HMGB1 and Caveolin-1 protein upregulation and HMGB1 translocation, while Caveolin-1 expression was downregulated when there was more than 10μM A2E. Our data indicate that A2E-induced upregulation of HMGB1、Caveolin-1 and HMGB1 release may relate to RPE cell senescence and play a role in the pathogenesis of AMD.

Eur J Pharmacol 2020; 882:173309. [PMID: 32598952 DOI: 10.1016/j.ejphar.2020.173309] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Revised: 06/20/2020] [Accepted: 06/22/2020] [Indexed: 01/12/2023]
Abstract
Studies have shown that the ginsenoside Rg1 can improve depressive symptoms in vitro and in vivo. However, the efficacy of Rg1on the hippocampal astrocyte gap junctions in depression are unclear. We mainly aimed to explore the relationship between Rg1, hippocampal astrocyte gap junctions and depression. Using primary cultured astrocytes, corticosterone (CORT) was used to induce stress. CORT (100 μM) significantly reduced the survival rate in astrocytes, and this effect was prevented by additional Rg1 administration. Interestingly, the gap junction blocker carbenoxolone (CBX) was able to revert this Rg1 effect. In in vivo models, one group was exposed to chronic unpredictable stress (CUS) for 47 days, while another group was bilaterally injected with CBX (100 μM) into the hippocampal CA1 region. Rats treated with Rg1 (20 mg/kg) showed an improvement in the sucrose preference and the forced swimming test in both models, indicating an antidepressive activity of Rg1. The levels of astrocyte gap junction connexin 43 (Cx43) were detected by immunofluorescence (IF) and western blotting. The levels of glial fibrillary acidic protein (GFAP) were detected by IF. The gap junctions in the hippocampal CA1 area were evaluated using dye transfer and electron microscopy. The reduction in Cx43 expression, the decrease in the Cx43 to GFAP ratio, the shorter dye diffusion distance, and the abnormal ultrastructure of gap junctions in rats exposed to CUS were markedly alleviated by concomitant Rg1 treatment. Taken together, the ginsenoside Rg1 could improve depression-like behavior in rats induced by astrocyte gap junction dysfunction in the hippocampus.

Rosiglitazone alleviates myocardial apoptosis in rats with acute myocardial infarction via inhibiting TLR4/NF-κB signaling pathway. Exp Ther Med 2020; 19:2491-2496. [PMID: 32256726 PMCID: PMC7086202 DOI: 10.3892/etm.2020.8479] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Accepted: 12/19/2019] [Indexed: 01/02/2023] Open
Abstract
Influence of rosiglitazone on the myocardial apoptosis in rats with acute myocardial infarction (AMI) via the Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway was explored. A total of 30 healthy male Sprague-Dawley (SD) rats were randomly divided into group A (Sham group, n=10), group B (AMI model group, n=10) and group C (AMI model + rosiglitazone group, n=10) using a random number table. It was observed through H&E staining that group A had myocardial cells with normal morphology and infiltration of few inflammatory factors, while group B had swollen myocardial cells with disorderly and irregular morphology, large and dark-colored nuclei, infiltration of massive inflammatory factors, large amounts of fibrous tissue hyperplasia in the intercellular space, disorderly arranged, thickened and lengthened myocardial fibers with widened gaps. Moreover, group C exhibited infiltration of fewer inflammatory factors and more normal myocardial tissue structure compared with group B. According to the sirius-red staining results, group A had normally arranged myocardial cells with a small amount of collagen hyperplasia, while group B had collagen interstitial hyperplasia and higher content of myocardial collagen than group A. Compared with that in group B, the myocardial collagen deposit was substantially reduced in group C. TUNEL staining results showed that the apoptosis rate of rat myocardial cells in group B was obviously higher than that in group A (40.37 vs. 5.23%), and it was notably lower in group C than that in group B (24.82 vs. 40.37%). According to the western blot results, the protein expression levels of the inflammatory factors TLR-4 and NF-κB in rat myocardial tissues were notably raised in group B compared with those in group A, and they were evidently lower in group C than those in group B. Rosiglitazone inhibits the TLR4/NF-κB signaling pathway to produce a myocardioprotective effect.
