However, immunogenicity and safety of COVID-19 vaccines in various populations are not well identified yet. Therefore, this study aimed to elucidate the efficacy and safety of the BBIBP-CorV (Sinopharm) and ChAdOx1 nCoV-19 (Oxford-AstraZeneca) vaccines in healthy subjects and patients with autoimmune diseases.<b>Methods:</b> Study population included 121 healthy subjects and 100 patients with autoimmune diseases. Immunization was performed based on the national vaccination protocols. Of the 221 volunteers, 201 subjects received Sinopharm and 20 cases were vaccinated with Oxford-AstraZeneca<b>.</b> During a 1-year follow-up, the immunogenicity was measured by ELISA before primary vaccination and 1 to 3 months after secondary immunization. Side effects were studied before entering the study and 1 week after the second dose.<b>Results:</b> Vaccination had a positive impact on the induction of immunogenic response (<i>p</i> < .0001). The rates of seropositive vaccine responses were 80% and 75% in subjects vaccinated with the Sinopharm and Oxford-AstraZeneca, respectively. The neutralizing antibody values were significantly higher in subjects with autoimmune diseases than those without autoimmunity (<i>p</i> < .05). The rate of adverse events were 38% and 42% in subjects vaccinated with the Sinopharm and Oxford-AstraZeneca, respectively. The rates of immunogenic responses induced with the Sinopharm and Oxford-AstraZeneca were, respectively, 76% and 81.5% in seropositive subjects, while they were 63.8% and 79.1% in seronegative subjects vaccinated with the Sinopharm and Oxford-AstraZeneca, respectively. Individuals previously infected with SARS-CoV-2 showed a significant reduction in the value of SARS-CoV-2 neutralizing antibodies compared with seronegative subjects (<i>p</i> < .01-.05).

A skin barrier-disrupted mouse model was induced by tape stripping. This study investigated the antioxidative and anti-inflammatory properties of antioxidants on PM-induced changes using the skin barrier-disrupted mouse model. Tape strips were attached to the back of 7-week-old nude mice and removed quickly. To investigate variations in skin hydration, levels of inflammatory cytokines, and indicators of keratinocyte differentiation, mice underwent treatment with several compounds: a control vehicle (100 μL), PM<sub>10</sub> 100 μL (100 μg/mL), PM<sub>10</sub> 100 μL (100 μg/mL) with antioxidants 100 μL (Punicalagin 5 μM, Dieckol 5 μM, EGCG 1 μM, resveratol 1 μM) for 1 week.

Cur has been recognized for its significant role in combating various types of tumors. However, the intrinsic molecular mechanisms through which it affects OS remain uncharted. In this study, we performed network pharmacology methods including protein-protein interaction (PPI) and core target screening, Functional Enrichment Analysis and Network Construction, Molecular Docking, which obtained the potential target of Cur. Meanwhile, cell experiments (wound healing assay, Transwell assay, Western blots, immunofluorescence, et al.) in vitro were performed to verify the targets, and reveal the biological mechanisms. A total of 18 hub genes were identified through our network pharmacological analysis. In vitro studies show that Cur inhibits the proliferation, migration, invasion capabilities of MG63 and U2OS cells. Western blot reveals a down-regulation of p-PI3K, PI3K, p-Akt, Akt, EGFR, Src, p-Src (Tyr416) and STAT3 expression when treated with Cur. Additionally, Cur upregulated epithelial proteins (E-cadherin and Occludin) while decreasing the expression of the mesenchymal protein (N-cadherin). In addition, Cur treatment decreases the EGFR/Src signaling pathway in the presence of active Src overexpression. Cur inhibits the proliferation, migration, invasion, epithelial-mesenchymal transition (EMT) by down-regulating EGFR/Src signaling axis, also resulting in coordinated weakening of its downstream regulatory genes, including Akt, STAT3, Bcl2, ERK1/2, among others signal axis (PI3K/Akt signaling pathway).</p>","PeriodicalId":48647,"journal":{"name":"International Journal of Immunopathology and Pharmacology","volume":"38 ","pages":"3946320241308082"},"PeriodicalIF":3.5,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11663267/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Myositis-specific autoantibodies (MSAs) are a useful aid in diagnosis DM and identifying its clinical subtype. During the COVID-19 pandemic, several studies found clinical similarities regarding lung involvement in both COVID-19 and DM. Such similarities have prompted speculation of a common pathogenetic mechanism. Indeed, viral infections are well-known triggers of autoimmune diseases. This prompted us to investigate whether circulating MSAs could be markers of the severity of lung involvement and of clinical outcome in COVID-19 patients. Moreover, we investigated the presence of cutaneous signs of DM in COVID-19 patients.</p><p><strong>Methods: </strong>We conducted a retrospective cohort study on 178 hospitalized patients affected by COVID-19. The diagnosis was confirmed by naso-pharyngeal swab positivity for SARS-CoV-2. The severity of lung involvement was assessed by assigning to each patient a radiological score ranging from 1 to 4, based on chest imaging (chest X-rays or CT scans). Serum samples were tested for MSAs.</p><p><strong>Results: </strong>Anti-PL-7 antibodies were detected in 10.1% of patients and were found to be associated with an increased risk of severe pulmonary involvement (<i>p</i> = 0.019) and a worse prognosis in COVID-19 patients.
