Antioxidants (Basel) 2024; 13:644. [PMID: 38929083 PMCID: PMC11200497 DOI: 10.3390/antiox13060644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 05/14/2024] [Accepted: 05/23/2024] [Indexed: 06/28/2024] Open
Abstract
This study was conducted to investigate the effects of dietary phosphatidylserine (PS) supplementation on the growth performance, stress response, non-specific immunity and antioxidant capacity of juvenile blunt snout bream (Megalobrama ambylcephala) cultured under a high stocking density. A 2 × 2 two-factorial design was adopted, including two stocking densities (10 and 20 fish/m3) and two dietary PS levels (0 and 50 mg/kg). After the 12-week feeding trial, the high stocking density significantly decreased the final weight; weight gain rate; specific growth rate; feed intake; nitrogen retention efficiency; plasma complement 3 (C3) level; albumin/globulin (ALB/GLB, A/G) ratio; activity of myeloperoxidase, lysozyme (LZM) and glutathione peroxidase (GPX); gpx transcription; and abundance of sirtuin3 (Sirt3) and nuclear factor erythroid-2-related factor 2 (Nrf2). However, it significantly increased the plasma levels of cortisol, glucose (GLU), lactic acid (LD), total protein and GLB; hepatic malondialdehyde (MDA) content; and sirt1 transcription. PS supplementation significantly increased the plasma ALB and C4 levels; the A/G ratio; the activity of LZM, CAT and GPX; the transcription of sirt1, nrf2, manganese-containing superoxide dismutase and catalase; and the Nrf2 abundance. However, it significantly decreased the plasma levels of cortisol, GLU and GLB, as well as the hepatic MDA content. In addition, there was a significant interaction between the stocking density and PS supplementation regarding the effects on the plasma LD, ALB, GLB and C3 levels; A/G ratio; hepatic CAT activity; and protein abundance of Sod2. In conclusion, PS supplementation can counteract the high stocking density-induced stress response, redox imbalance and immunosuppression in blunt snout bream.

Abstract
Myocarditis is a disease characterized by inflammation of the heart muscle, which increases the risk of dilated cardiomyopathy and heart failure. Macrophage migration is a major histopathological hallmark of myocarditis, making macrophages a potential therapeutic target for the management of this disease. In the present study, we synthesized a bioinspired anti-inflammatory nanomedicine conjugated with protein G (PSL-G) that could target macrophages and induce macrophage polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype. Notably, PSL-G exhibited a higher affinity for macrophages than non-macrophage cells. The addition of PSL-G decreased the levels of pro-inflammatory cytokines (e.g., IL-1α, IL-6, and TNF-α), but increased the level of the anti-inflammatory cytokine IL-10 in macrophages treated with lipopolysaccharide and/or interferon-γ. Furthermore, the lifetime of PSL-G in murine blood circulation was found to be significantly higher than that of PSL. Systemic injection of PSL-G into a mouse model of experimental autoimmune myocarditis remarkably reduced macrophage migration in the myocardium (16-fold compared with the positive control group) and myocardial fibrosis (8-fold). Based on these results and the fact that macrophages play a critical role in the pathogenesis of various diseases, we believe that bioinspired macrophage-targeted anti-inflammatory nanomedicines may be effective therapeutic options for the treatment of autoimmune and autoinflammatory diseases, especially myocarditis.

Abstract
Asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis (CF) are major inflammatory respiratory diseases. Current mainstay therapy for asthma, and chronic obstructive pulmonary disease are corticosteroids, which have well-established side effect profiles. Phospholipids (PLs) are ubiquitous, diverse compounds with varying functions such as their structural role incell membrane, energy storage, and cell signaling.Recent advances in understanding PLs role as inflammatory mediators in the body as well as their widespread long-standing use as carrier molecules in drug delivery demonstrate the potential application of phospholipids in modulating inflammatory conditions. This review briefly explains the main mechanisms of inflammation in chronic respiratory diseases, currentanti-inflammatory treatments and areas of unmet need. The structural features, roles of endogenous and exogenous phospholipids, including their use as pharmaceutical excipients are reviewed. Current research on the immunomodulatory properties of PLs and their potentialapplication in inflammatory diseasesis the major section of this review. Considering the roles of PLs as inflammatory mediators and their safety profile established in pharmaceutical formulations, these small molecules demonstrate great potential as candidates in respiratory inflammation. Future studies need to focus on the immunomodulatory properties and the underlying mechanisms of phospholipids in respiratory inflammatory diseases.

Abstract
Apoptotic cells are known to suppress microglial inflammation in the brain by presenting phosphatidylserine. In this study, we newly designed polymeric particles that expose the anti-inflammatory site of phosphatidylserine to serve as an apoptotic cell-mimetic anti-inflammatory platform. The prepared anti-inflammatory particles showed no cytotoxicity and significantly inhibited the production of the inflammatory cytokine interleukin-6 against lipopolysaccharide stimulation in the microglia cell line MG6. This novel polymeric particle has potential for establishing a "cell-free" apoptotic cell-mimetic treatment for intracerebral inflammation.
