The systemic inflammation triggered by psoriasis contributes significantly to increased cardiovascular risk. While various treatments completely clear the skin, the associated effects on systemic inflammation are not yet clear. We investigated residual systemic inflammation in successfully treated patients. Circulating disease-specific and non-specific inflammatory markers were measured and compared in 80 psoriasis patients (aged 30-45 years) successfully treated with topical therapy, methotrexate, adalimumab, secukinumab or guselkumab, and in 20 healthy controls. Non-specific inflammatory markers (high-sensitivity C-reactive protein (hs-CRP), complete blood count (CBC) parameters, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume-to-platelet ratio (MPR), and red blood cell distribution width-to-platelet ratio (RPR)) and disease-specific inflammatory markers (interferon-γ (IFN-γ), tumor necrosis factor (TNF), interleukin (IL)-1β, IL-12p70, IL-17, and IL-23) were measured and compared between groups. Disease-specific cytokines (IFN-γ, TNF, IL-1β, IL-12p70, and IL-17, but not IL-23), were significantly elevated in patients compared to controls, while non-specific inflammatory markers showed no differences compared to controls. The residual disease-specific cytokines were similarly elevated in all five treated groups. In addition, they correlated significantly with body mass index (BMI) and waist circumference. Our results suggest that psoriasis patients have elevated residual disease-specific cytokines despite successful treatment, while the non-specific inflammatory markers are similar to those in control subjects. Residual disease-specific inflammatory markers correlated with BMI and waist circumference. A possible beneficial effect of body weight control in psoriasis patients merits further investigation.

Based on our recent finding to study the potential effect of mTOR on ATG13 inactivation in chronic muscle fatigue, we report that biweekly oral administration with MHY1485, a potent inducer of mTOR, develops chronic illness in mice resulting in severe muscle weakness. As a mechanism, we observed that MHY1485 feeding impaired ATG13-dependent autophagy, caused the infiltration of inflammatory M1 macrophages (Mφ), upregulated IL6 and RANTES by STAT3 activation, and augmented demyelination in muscle-serving nerve fibers. Interestingly, these mice displayed worsened muscle fatigue during 2-day post-treadmill exercise, suggesting the critical role of chronic mTOR activation in potential PEM pathogenesis. Interestingly, ATG13-repressor mice exhibited enhanced infiltration of M1Mφ cells, STAT3 activation, demyelination of nerve fibers, and PEM-like symptoms, suggesting the potential role of ATG13 impairment in post-exertional fatigue. HIGHLIGHTS: The potential role of mTOR activation in post-exertional fatigue is highlighted. As a molecular mechanism, mTOR activation augments autophagy impairment via ATG13 inactivation.

Data were obtained from the Global Burden of Disease (GBD) 2021 study. Trends in ASIR, ASPR, and ASMR were analyzed using Joinpoint regression to calculate annual percentage change (APC) and average APC (AAPC). Bayesian age-period-cohort (BAPC) modeling was applied to project future ASIR trends. In 2021, asthma had the highest ASIR (364.17/100,000), followed by psoriasis (59.70/100,000) and RA (13.70/100,000), while MS (0.16/100,000) and IBD (1.40/100,000) were the least common. Asthma exhibited significant declines in ASIR (-1.23% AAPC), ASPR (-1.49%), and ASMR (-4.4%). Conversely, T1DM showed rising ASIR (+ 1.16%) and ASPR (+ 1.15%) alongside declining ASMR (-2.62%). Psoriasis (+ 0.74%) and IBD (+ 2.09%) also showed rising ASIR. Gender differences were notable, with greater T1DM ASIR increases in males and more significant asthma improvements in females. By 2046, the ASIR of T1DM, psoriasis, and RA is projected to reach 5.8, 80.9, and 15.54 per 100,000, respectively, while asthma is expected to decline to 330.98 per 100,000.

Study quality was evaluated with the Critical Appraisal Skills Programme Tool. A meta-analysis was conducted using a random-effects model. Heterogeneity and publication bias were assessed. Eleven eligible studies (with 5-73 vaccinated immunocompetent participants) were identified.

In conclusion, following the second or third COVID-19 mRNA vaccine dose, QuantiFERON SARS-CoV-2 detected positive responses in a certain percentage of the vaccinees, possibly because of waning immunity, reduced assay sensitivity, or lack of T-cell response induction in some vaccinees.

In order to maintain tolerance or initiate immune responses, DCs must be activated in a balanced and regulated manner via diverse signaling pathways. By using a variety of pharmacological components, we can interfere with their different signaling pathways such as the mammalian target of rapamycin (mTOR) to appropriately modulate DC activity. In the current study, we administered RAD001 to DCs to examine the impact of mTOR inhibition on both the maturation stage and the expression of inflammatory and anti-inflammatory molecules in DCs. Pure monocytes were cultivated and stimulated with GM-CSF and IL-4 to generate immature DCs, which were then treated with RAD001. The phenotype of the DCs was determined by labeling surface markers and analyzing them using flow cytometry. Afterward, real-time PCR was carried out to evaluate the expression of inflammatory and anti-inflammatory genes. The administration of RAD001 to DCs led to a significant upregulation in the gene expression of inflammatory molecules such as IL-12, IL-1β, tumor necrosis factor (TNF)-α, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-KB). Conversely, RAD001 treatment resulted in a decrease in the gene expression of anti-inflammatory factors IL-10 and indoleamine 2,3-dioxygenase (IDO).

Immune checkpoint receptor (ICR) expressions, intracellular cytokines, and cytotoxic capacity of NK cell subsets were analyzed by flow cytometry. Circulatory levels of sPD-1, sCTLA-4, sLAG-3, and sTIGIT were determined by ELISA. PD-1, CTLA-4, and LAG-3 expressions of both cytotoxic (CD56<sup>neg/dim</sup>CD16<sup>bright</sup>) and cytokine-producing (CD56<sup>bright/dim</sup>CD16<sup>neg</sup>) NK cells increased in tumor tissue compared to both peripheral and tumor-draining veins. NK cells expressing PD-1, CTLA-4, or LAG-3 had significantly lower IFN- <math><mi>γ</mi></math> and TNF- <math><mi>α</mi></math> and increased IL-10 expressions in tumor tissue compared to peripheral venous blood. The cytotoxic activity (perforin and granzyme A expressions) of NK cells from tumor tissue was significantly reduced compared to peripheral blood. Soluble ICRs decreased in peripheral blood and tumor-draining vein of the patients compared to peripheral blood of healthy individuals. However, NK cell phenotype and functions were similar in peripheral blood and tumor-draining vein. NSCLC tumor microenvironment impacts ICR expressions in NK cells, and ICR-expressing NK cells have impaired inflammatory cytokine secretion and cytotoxic activities with a regulatory phenotype. However, tumor-draining venous blood did not reflect the immune status of the tumor tissue.</p>","PeriodicalId":13389,"journal":{"name":"Immunologic Research","volume":"73 1","pages":"18"},"PeriodicalIF":3.3,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142853999","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}
