Although genetic testing is commonly employed for FMF diagnosis, the interpretation of genetic results is often challenging. Therefore, we aimed to functionally characterise the p.R202Q MEFV alteration. Furthermore, we hypothesized that inflammation may affect genomic stability and neutrophilic (N) subsets. A cohort comprising patients with FMF (n = 4), p.R202Q variant (n = 18) and FMF-like (n = 8) were selected from the Outpatient Clinic for Autoinflammatory diseases of Padova University Hospital. Primary monocytes were incubated for 3 h in the presence of LPS or LPS + PKN1/2 inhibitor (UCN-01). Colchicine pretreatment was applied to assess its anti-inflammatory effect. Pro-inflammatory cytokines were measured by ELISA and leukocytes were examined using May-Grünwald-Giemsa staining on blood smears. We did not find significant differences in IL-1 and IL-18 levels in monocytes treated with LPS + UCN-01 between p.R202Q patients and healthy donors (HDs). The levels of IL-1β released from LPS-stimulated patients were higher in p.R202Q patients than in HDs. We found that immature and hypersegmented neutrophils were higher in p.R202Q patients than in HD. Nuclear abnormalities were higher in FMF and p.R202Q patients than in HD. Finally, we found a higher cell rate in leukocytes from p.R202Q patients than in HDs. The p.R202Q variant did not appear to affect pyrin function, albeit these patients presented cytological alterations similar to those observed in FMF patients.

This study investigates the association between TLR7 variants and susceptibility to severe COVID-19 in a multicentric Spanish cohort. The TLR7 gene was sequenced in a cohort of 365 COVID-19 patients, stratified into two groups: one comprising mild and asymptomatic patients, considered as controls (n = 87), and the other consisting of moderate to severely affected patients hospitalized due to COVID-19 pneumonia, considered as cases (n = 278). A total of 152 unique TLR7 variants were identified, of note, six rare variants were identified in 11 cases (3.96%), all of whom belonged to the case group. The functional impact of rare TLR7 variants was assessed using a luciferase reporter assay and revealed that N215S is a loss-of-function (LOF) variant, while D332G exhibits an hypomorphic behavior. Conversely, H90Y, V219I, A448V, and R902K maintained normal signaling. No skewed X-inactivation was observed in female carriers of N215S or D332G. In addition, the common variants Q11L (rs179008), c.4-151A>G (rs179009) and c.*881C>G (rs3853839) were associated with severe pneumonia, while c.4-151A>G (rs179009) was specifically linked to Intensive Care Unit (ICU) admission. These findings highlight the role of TLR7 in antiviral immune response and its association with severe COVID-19 in men. The luciferase assay proves to be a reliable tool for evaluating TLR7 signaling, effectively distinguishing between neutral, LOF, and gain-of-function (GOF) variants. Further research is needed to better understand TLR7 variants and its implications in immunodeficiency and immune dysregulation.</p>","PeriodicalId":15531,"journal":{"name":"Journal of Clinical Immunology","volume":"45 1","pages":"100"},"PeriodicalIF":7.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12116960/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144150563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
