The patients were divided into four main groups based on disease severity: mild (n = 7), moderate (n = 10), severe (n = 14), and critical (n = 9). Individuals aged < 18 years and pregnant women were excluded. Patients were classified according to the World Health Organization (WHO) classification system (WHO/2019-nCoV/clinical/2021.1).ResultsConsidering all groups, statistically significant differences were detected among all groups for both CASP8(2-Delta Delta Ct) (p = 0.006) and MAPK1 2(-Delta Delta Ct) values (p = 0.015). Moreover, statistically significant differences were detected between mild and moderate (p = 0.013), moderate and critical (p = 0.018), and severe and critical (p = 0.023) groups for lymphocytes.ConclusionThe CASP8/MAPK1 expression levels and/or its products are essential in preventing injury caused by COVID-19 infection. They play crucial roles in maintaining cellular homeostasis and viability. Furthermore, CASP8/MAPK1 levels can provide information about disease severity.eninfo:eu-repo/semantics/openAccessCASP8 geneCellular homeostasisMAPK1SARS-CoV-2Article10.1007/s11033-023-08244-43248436708447324150WOS:000921163100001Q3
