Although the mortality rate of the disease has been relatively under control as of 2022, more than 15 million confirmed COVID-19 cases have been detected in Turkey to date, causing more than 100,000 deaths. The clinical manifestation of the disease varies widely, ranging from asymptomatic to acute respiratory distress syndrome causing death. The immune response mechanisms have an important impact on the fine adjustment between healing and enhanced tissue damage. This study aims to investigate the relationship between the variants of the <i>interleukin 1 receptor antagonist (IL1RN), interleukin 17A (IL17A)</i>, and <i>interleukin 17F (IL17F)</i> genes and COVID-19 severity. The study population comprised 202 confirmed COVID-19 cases divided into three groups according to severity. The <i>IL1RN</i> variable number of a tandem repeat (VNTR) polymorphism was genotyped by polymerase chain reaction (PCR), and <i>IL17A</i> rs2275913, <i>IL17F</i> rs763780 and rs2397084 polymorphisms were genotyped by the PCR-based restriction fragment length polymorphism method. Statistical analysis revealed a significant association between <i>IL17A</i> rs2275913 variant and COVID-19 severity. The AA genotype and the A allele of <i>IL17A</i> rs2275913 were found significant in the severe group. Additionally, we found a significant relationship between haplotype frequency distributions and severity of COVID-19 for the <i>IL17F</i> rs763780/rs2397084 (p = 0.044) and a combination of <i>IL17F</i> rs763780/rs2397084/ <i>IL17A</i> rs2275913 (p = 0.04).

Studies have found that LILRBs receptor can bind to a variety of ligands and has a variety of biological functions such as regulating inflammatory response, immune tolerance and cell differentiation. Inflammatory reaction plays a vital role in resisting microorganisms. The function of inhibitory immune receptors can recognize the signs of infection and promote the function of anti-microbial effect. The inflammatory response must be strictly regulated to prevent excessive inflammation and tissue damage. Therefore, it is of general interest to understand the role of LILRBs in the inflammatory response. Because they can inhibit the anti-microbial response of neutrophils, some human pathogens use these receptors to escape immunity. This article reviews the biological role of LILRBs in the inflammatory response. We focus on the known ligands of LILRBs, their different roles after binding with ligands, and how these receptors help to form neutrophil responses during infection. Recent studies have shown that LILRBs recruit phosphatases through intracellular tyrosine-based immunoreceptor inhibitory motifs to negatively regulate immune activation, thereby transmitting inflammation-related signals, suggesting that LILRBs may be an ideal target for the treatment of inflammatory diseases.

Lee and Song looked for publications reporting IL17 polymorphisms in asthma patients and healthy controls using the PubMed/Medline and Embase databases (Lee & Song, 2023). Asthma susceptibility was studied using meta-analyses to examine the relationships between IL17Ars8193036 (−737C/T), rs2275913 (−197G/A), rs3819024 (A/G), rs3748067 (C/T), and rs4711998 (A/G) polymorphisms and (Lee & Song, 2023) IL17F rs763780 (7488A/G). According to Lee and Song, no correlation between this polymorphism and asthma could be established utilizing the allele contrast, dominant, or homozygous contrast models. In this meta-analysis, no proof of a relationship between any other IL17A and IL17F polymorphism and asthma susceptibility was discovered (Lee & Song, 2023). Finally, Lee and Song found that only the CC genotype of the IL17A rs8193036 polymorphism is linked to asthma susceptibility (Lee & Song, 2023). In this study, the impact of a polymorphism is examined. The hereditary factor discussed in this article might or might not have an effect. We both agree that the targeted observation might be related to the investigated underlying genetic component. However, a variety of genetic variants have been connected to the levels of serum folate, cobalamin, and homocysteine. Examples include NLRP3, MAVS, and GSDM gene polymorphisms (Imraish et al., 2022; Xulong et al., 2022).

A total of 130 antibody-positive AIN patients, 64 with specific anti-HNA-1a antibodies and 66 with broad-reacting anti-FcγRIIIb antibodies, were genotyped with a multiplex ligation probe assay and compared with healthy controls. Positive findings were confirmed with real-time q-PCR. We determined copy numbers of the FCGR2 and FCGR3 genes and the following SNPs: <i>FCGR2A</i> Q62W (rs201218628), <i>FCGR2A</i> H166R (rs1801274), <i>FCGR2B</i> I232T (rs1050501), <i>FCGR3A</i> V176F (rs396991), haplotypes for <i>FCGR2B/C</i> promoters (rs3219018/rs780467580), <i>FCGR2C</i> STOP/ORF and HNA-1 genotypes in <i>FCGR3B</i> (rs447536, rs448740, rs52820103, rs428888 and rs2290834). Generally, associations were antibody specific, with all associations being representative of the anti-HNA-1a-positive group, while the only association found in the anti-FcγRIIIb group was with the HNA-1 genotype. An increased risk of AIN was observed for patients with one copy of <i>FCGR3B</i>; the HNA genotypes HNA-1a, HNA-1aa or HNA-1aac; the <i>FCGR2A</i> 166H and <i>FCGR2B</i> 232I variations; and no copies of <i>FCGR2B</i> 2B.4. A decreased risk was observed for HNA genotype HNA-1bb; <i>FCGR2A</i> 166R; <i>FCGR2B</i> 232T; and one copy of <i>FCGR2B</i> promoter 2B.4. We conclude that in our Danish cohort, there was a strong association between variation in the FCGR locus and AIN. The findings of different genetic associations between autoantibody groups could indicate the presence of two different disease entities and disease heterogeneity.</p>","PeriodicalId":14003,"journal":{"name":"International Journal of Immunogenetics","volume":"50 2","pages":"65-74"},"PeriodicalIF":2.2,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/iji.12614","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9151110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
