Materials and Methods: For this purpose, the binding affinities of Nsp11-derived peptides to 12 major histocompatibility complex (MHC) supertype representative human leukocyte antigen (FILA) alleles were predicted by NetMHCcons and NetCTLpan. Strongly binding or predicted epitope peptides were sought in human proteome by blastp. Whether the sequence containing the overlapping peptide had a strong binding affinity to the same HLA allele as the Nsp11 peptide was also checked. Results: One of the Nsp11-derived peptides was predicted to be strongly bound to the HLA-B*15:01 allele and the other to be the cytotoxic T lymphocyte (CTL) epitope that binds to the HLA-A*01:01 allele. Alignment result with inununoglobulin heavy chain junction region (MOP92462.1) appeared on top within the blastp search results for peptides. A peptide of the sequence containing the overlapping peptide was predicted to be the CTL epitope that binds to the BLA-B*15:01 allele. Conclusion: The results indicate that individuals with the HLA-B*15:01 allele may have a risk of autoimmune reactions from SARS-CoV-2 infection.","PeriodicalId":41088,"journal":{"name":"Turkish Journal of Immunology","volume":"24 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86529032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pathogenesis and clinical manifestations of COVID-19 disease are tightly influenced by the host immune response to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. In some condition, the immune response might be uncontrolled, giving rise to hyperinflammatory conditions marked by excessive release of proinflammatory cytokines (cytokine storms) in severe COVID-19 patients, which then can cause acute respiratory distress syndrome (ARDS), multiorgan failure, and death. Furthermore, treatment using immunomodulator agents including immunostimulatory and immunosuppressive agents can be an option in achieving successful treatment. In this review, we discuss the pathogenesis of the disease, including host immune responses to SARS-CoV-2 virus infection, and immune mechanisms which contribute to the disease severity and death as well as several potential immunomodulatory agents which can be used in the management of hyperinflammatory syndrome of severe COVID-19.","PeriodicalId":41088,"journal":{"name":"Turkish Journal of Immunology","volume":"144 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81373322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While COVID-19 cases are seen in all age groups, death rates are high in cases of cancer that cause immunodeficiency. especially in elderly people with impaired immune systems, in those with chronic diseases. The interaction between infections and the immune system is clear and there is a lot of relevant literature information. By keeping the immune system strong. infections can be overcome with less damage. and the harmful effects of inflammation and death rates can be reduced.

Materials and Methods: We conducted a retrospective, cross-sectional study between January 1st, 2015 and January 1st, 2016. We focused on the positive CLIFT results firstly, then, we compared the ANA-IFA, ELISA, and ANA-IB results to diagnose SLE. Demographic features were obtained from the hospital records. Results: To analyse CLIFT, 3242 seras were tested, and 72 (2.2%) were positive. Among CLIFT positivity [n=64; 57 female, 7 male (mean, range; 41.96, 11–82)]; 73% (n=47) had SLE. Out of 61 patients were analyzed by ANA-IFA, 36 had peripheral (n=1) and homogenous (n=35) patterns; 83% (n=30) had SLE. Out of 46 patients were analyzed by ANA-IB, 30 had dsDNA; 73% (n=22) had SLE. Out of 25 patients who were analyzed by ELISA, 18 had dsDNA; 83% (n=15) had SLE. In the two-sided correlations, CLIFT positivity (≥grade 2) was found to be statistically significantly associated with having SLE (p=0.005, r [64]=0.92); CLIFT positivity was also statistically significantly associated with ANA-IFA (p=0.003, r=0.85). In order to exclude SLE diagnosis, CLIFT positivity was statistically significantly correlated with ANA-IB (p=0.002, r=0.90). Conclusion: CLIFT can not be used instead of ELISA and ANA-IB, but it can reduce their usage. We recommend to use CLIFT and ANA-IFA for first-line screening; and ANA-IB and ELISA for confirmation and identification of dsDNA.","PeriodicalId":41088,"journal":{"name":"Turkish Journal of Immunology","volume":"21 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87336613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
