Abstract
BACKGROUND In Duchenne muscular dystrophy (DMD), the immune system cells (ISC) synthesize molecules to regulate inflammation, a process needed to regenerate muscle. The relationship between those molecules and the muscle injury is unknown. Monocytes belonging to ISC are regulated by omega-3 fatty acids (ω-3 LCPUFAs) in DMD, but whether those fatty acids influence other ISC like T-cells is unknown. OBJECTIVE We analyzed the expression of the muscle regeneration markers (FOXP3 and AREG) in circulating leukocytes of DMD patients with different lower limb muscle functions and whether ω-3 LCPUFAs regulate the expression of those markers, and the populations of circulating T-cells, their intracellular cytokines, and disease progression (CD69 and CD49d) markers. METHODS This placebo-controlled, double-blind, randomized study was conducted in DMD boys supplemented with ω-3 LCPUFAs (n = 18) or placebo (sunflower oil, n = 13) for six months. FOXP3 and AREG mRNA expression in leukocytes, immunophenotyping of T-cell populations, CD49d and CD69 markers, and intracellular cytokines in blood samples were analyzed at baseline and months 1, 2, 3, and 6 of supplementation. RESULTS Patients with assisted ambulation expressed higher (P = 0.015) FOXP3 mRNA levels than ambulatory patients. The FOXP3 mRNA expression correlated (Rho = -0.526, P = 0.03) with the Vignos scale score at month six of supplementation with ω-3 LCPUFAs. CD49d + CD8 + T-cells population was lower (P = 0.037) in the ω -3 LCPUFAs group than placebo at month six of supplementation. CONCLUSION FOXP3 is highly expressed in circulating leukocytes of DMD patients with the worst muscle function. Omega-3 LCPUFAs might modulate the synthesis of the adhesion marker CD49d + CD8 + T-cells, but their plausible impact on FOXP3 needs more research.

Abstract
Malaria, caused by Plasmodium protozoal parasites, remains a leading cause of morbidity and mortality. The Plasmodium parasite has a complex life cycle, with asexual and sexual forms in humans and Anopheles mosquitoes. Most antimalarials target only the symptomatic asexual blood stage. However, to ensure malaria eradication, new drugs with efficacy at multiple stages of the life cycle are necessary. We previously demonstrated that arsinothricin (AST), a newly discovered organoarsenical natural product, is a potent broad-spectrum antibiotic that inhibits the growth of various prokaryotic pathogens. Here, we report that AST is an effective multi-stage antimalarial. AST is a nonproteinogenic amino acid analog of glutamate that inhibits prokaryotic glutamine synthetase (GS). Phylogenetic analysis shows that Plasmodium GS, which is expressed throughout all stages of the parasite life cycle, is more closely related to prokaryotic GS than eukaryotic GS. AST potently inhibits Plasmodium GS, while it is less effective on human GS. Notably, AST effectively inhibits both Plasmodium erythrocytic proliferation and parasite transmission to mosquitoes. In contrast, AST is relatively nontoxic to a number of human cell lines, suggesting that AST is selective against malaria pathogens, with little negative effect on the human host. We propose that AST is a promising lead compound for developing a new class of multi-stage antimalarials.

Biochim Biophys Acta Mol Cell Biol Lipids 2021; 1866:159016. [PMID: 34332075 DOI: 10.1016/j.bbalip.2021.159016] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Revised: 06/28/2021] [Accepted: 07/25/2021] [Indexed: 12/16/2022]
Abstract
A high intake in polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acid (EPA) (C20:5 n-3), is cardioprotective. Dietary PUFAs incorporate into membrane phospholipids, which may modify the function of membrane proteins. We investigated the consequences of the membrane incorporation of several PUFAs on the key antiatherogenic ABCA1-mediated cholesterol efflux pathway. Human THP-1 macrophages were incubated with EPA, arachidonic acid (AA) (C20:4 n-6) or docosahexaenoic acid (DHA) (C22:6 n-3) for a long time to mimic a chronic exposure. EPA 70 μM, but not AA 50 μM or DHA 15 μM, increased ABCA1-mediated cholesterol efflux to apolipoprotein (apo) AI by 28% without altering aqueous diffusion. No variation in ABCA1 expression or localization was observed after EPA treatment. EPA incorporation did not affect the phenotype of THP-1 macrophages. The membrane phospholipids composition of EPA cells displayed higher levels of both EPA and its elongation product docosapentaenoic acid, which was associated with drastic lower levels of AA. Treatment by EPA increased the ATPase activity of the transporter, likely through a PKA-dependent mechanism. Eicosanoids were not involved in the stimulated ABCA1-mediated cholesterol efflux from EPA-enriched macrophages. In addition, EPA supplementation increased the apo AI binding capacity from macrophages by 38%. Moreover, the increased apo AI binding in EPA-enriched macrophages can be competed. In conclusion, EPA membrane incorporation increased ABCA1 functionality in cholesterol-normal human THP-1 macrophages, likely through a combination of different mechanisms. This beneficial in vitro effect may partly contribute to the cardioprotective effect of a diet enriched with EPA highlighted by several recent clinical trials.
