This study investigated the potential role of TAM receptors in individuals diagnosed with idiopathic inflammatory myopathies (IIM). Clinical data and serum samples were obtained from 176 patients with IIM and 50 healthy controls (HCs). The levels of soluble TAM (sTAM) receptors were measured through enzyme-linked immunosorbent assay. Additionally, Tyro3 protein expression in the muscle tissue of both patients and HCs was examined using western blot and immunohistochemistry (IHC) analyses. The levels of sTAM receptors were notably higher in IIM patients than in HCs. Specifically, serum concentrations of soluble Tyro3 (sTyro3) were markedly elevated among patients with dermatomyositis (DM) and immune-mediated necrotizing myopathy (IMNM). No significant differences were found in sTyro3 levels among IMNM patients with anti-signal recognition particle positive, anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase positive, and seronegative subtypes. Further, levels of sTyro3 showed an inverse relationship with the manual muscle testing-8 score, while exhibiting a positive correlation with serum creatine kinase. Following treatment, patients with IMNM and DM exhibited reduced sTyro3 levels. Results from western blotting and IHC revealed a significant expression of Tyro3 in the necrotic muscles of patients with IMNM and DM. This study demonstrated that Tyro3 causes muscle injury in patients with IIM; therefore, it is considered a potential biomarker and therapeutic target for patients with IIM.</p>","PeriodicalId":13389,"journal":{"name":"Immunologic Research","volume":"73 1","pages":"131"},"PeriodicalIF":3.1,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145075131","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}

Human peripheral blood mononuclear cells (PBMC) and Calu-3 cell lines (bronchial epithelial cells) were used to develop 2D and 3D models. Peptides: Spike-S1-His (S-His), nucleocapsid-His and adjuvants: human adenovirus five serotype-based viral vector (AdV-D24-ICOSL-CD40L), armed with inducible co-stimulator (ICOSL) and CD40 ligand (CD40L), and a vector lacking these transgenes (AdV5/3) were used due to their effective initial interaction with antigen-presenting cells (APC). Studying the potency of biologics in vitro revealed a significant increase in the percentage of CD4⁺ TCM, CD4⁺ TEMRA, and CD4⁺ TEM lymphocyte subpopulations involved in memory cell generation after 24 h of treatment. Prolonging the exposure for 7 days, a significant increase in CD4⁺ cells was observed when PBMCs were treated with AdV1 (56.00 ± 0.26% vs. 48.17 ± 1.10%). In contrast, a decrease in CD8⁺ cells was observed in those treated with AdV1 (37.93 ± 0.35%) compared to AdV1 + S-His + N-His (38.47 ± 0.38%) versus the untreated group (44.63 ± 1.07%). A decrease in EMRA was noted when PBMCs were treated with AdV1 + S-His + N-His (2.97 ± 0.23% vs. 4.50 ± 0.35%). Moreover, it was pointed out that PBMCs treated with AdV1 alone or in combination with S-His and N-His showed an elevated number of naïve CD4⁺/CD8⁺ and SCM CD4⁺/CD8⁺ cells. No changes in the number of EMRA CD4⁺ subpopulations were detected when PBMCs were treated with AdV2 compared with untreated ones (4.27 ± 0.06% vs. 4.50 ± 0.35%). Analysis of the humoral response induced by AdV1, AdV2, S-His, N-His, AdV1 + S-His + N-His, and AdV2 + S-His + N-His showed that AdV1 alone (4.17 ± 0.25% vs. 3.17 ± 0.06%) and in combination with S-His and N-His (3.87 ± 0.25 vs. 3.17 ± 0.06%) slightly increased the number of CD19⁺ cells. RNA-Seq analysis of PBMC cells in the 3D model revealed gene overexpression, including FGFR4, associated with the Rap1 pathway in samples exposed to AdV1 + S-His + N-His. Thus, the proposed platform's impact on lymphocyte differentiation was confirmed, and cytokine profile analysis in this sample revealed elevated levels of IL-10, IL-12p70, and IL-8. All samples exposed to AdV showed increased levels of IFN-γ. The safety and biodistribution studies of the vaccine platform demonstrated that a 30-day exposure did not impact mice's survival or organ morphology.

The current global pandemic preparedness initiatives have also promoted the preclinical evaluation of a new group of coronavirus vaccines.
