Experimental autoimmune encephalomyelitis (EAE) is laboratory model of MS widely used for CNS-associated inflammatory researches. Cell therapy using macrophage M2 (MPM2) is a cell type with anti-inflammatory characteristics for all inflammatory-based neuropathies. This experimental study investigated the probable therapeutic anti-inflammatory effects of intraperitoneal (IP) injection of MPM2 on alleviation of motor defect in EAE-affected animals.</p></div><div><h3>Materials and methods</h3><p>24 C57/BL6 female mice were divided into four groups of EAE, EAE + Dexa, EAE + PBS, and EAE + MP2. EAE was induced through deep cervical injection of spinal homogenate of guinea pigs. MPM2 cells were harvested from bone marrow and injected (10<sup>6</sup>cells/ml) in three days of 10, 13 and 16 post-immunizations (p.i). Clinical score (CS), anti-inflammatory cytokines (IL-4, IL-10), pro-inflammatory gene expression (TNF-α, IL-1β) and histopathological investigations (HE, Nissl and Luxol Fast Blue) were considered. Data were analyzed using SPSS software (v.19) and <em>p</em> &lt; 0.05 was considered significant level.</p></div><div><h3>Results</h3><p>During EAE induction, the mean animal weight was decreased (<em>p</em> &lt; 0.05); besides, following MPM2 injection, the weight gain was applied (<em>p</em> &lt; 0.05) in EAE + MPM2 groups than control. Increased (p &lt; 0.05) levels of CS was found during EAE induction in days 17–28 in EAE animals; besides, CS was decreased (p &lt; 0.05) in EAE + MPM2 group than EAE animals. Also, in days 25–28 of experiment, the CS was decreased (p &lt; 0.05) in EAE + MPM2 than EAE + Dexa. Histopathological assessments revealed low density of cell nuclei in corpus callosum, microscopically. LFB staining also showed considerable decrease in white matter density of corpus callosum in EAE group. Acceleration of white matter density was found in EAE + MPM2 group following cell therapy procedure. Genes expression of TNF-α, IL-1β along with IL-4 and IL-10 were decreased (<em>p</em> &lt; 0.05) in EAE + MPM2 group.</p></div><div><h3>Conclusion</h3><p>IP injection of MPM2 to EAE-affected female mice can potentially reduce the CNS inflammation, neuronal death and myelin destruction. MPM2 cell therapy can improve animal motor defects.</p></div>","PeriodicalId":23304,"journal":{"name":"Transplant immunology","volume":"85 ","pages":"Article 102067"},"PeriodicalIF":1.5,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141262882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
