Cytokines and inflammatory mediators have a major role in forming inflammation in HAM/TSP patients. This study aimed to measure the levels of IL-32, a proinflammatory cytokine associated with autoinflammatory disorders, and also cyclooxygenase -2 (COX-2) as a key mediator of inflammatory pathways in HAM/TSP patients and HTLV-1 asymptomatic carriers (ACs).Materials and Methods: Peripheral blood monocyte cells (PBMCs) were isolated from HAM/TSP patients, ACs, and healthy controls (HCs), and DNA and RNA were extracted to evaluate HTLV-1 proviral load (PVL) and expression of IL-32 and COX-2, using real-time PCR. Serum levels of IL-32 were determined by using an ELISA assay.Results: The expression level of IL-32 was significantly higher in ACs compared with HAM/TSP patients and HCs (p 0.05, respectively). There were no statistically significant differences in the expression levels of Cox-2 and protein levels of IL-32 between the study groups.  HTLV-1 PVL was higher in HAM/TSP patients compared with ACs.Conclusion:  Results showed increased mRNA levels of IL-32 in ACs. Since HTLV-1 PVL in ACs is lower than in HAM/TSP patients, it could be concluded that IL-32 might be an HTLV-1 inhibitor that seems to control virus replication. Despite the difference in IL-32 mRNA levels between study groups, no statistically significant differences were observed in IL-32 serum levels. Also, there were no significant differences in COX-2 expression.}, keywords = {Cyclooxygenase-2,HAM/TSP,HTLV-1,Interleukin-32,Inflammation}, url = {https://ijbms.mums.ac.ir/article_18254.html}, eprint = {https://ijbms.mums.ac.ir/article_18254_e6655363bc6589fd7e8ace55b4f83901.pdf} }
