Introduction. Dendritic cells (DCs) play a key role in antigen presentation and T cell activation, but their function can be modulated by the tumor microenvironment, affecting the antitumor immune response. This study focuses on the interaction between DCs and hepatocellular carcinoma (HCC), exploring how the tumor environment influences DC activity. Objective. To evaluate the variation in DC activity in response to the expression of proinflammatory cytokines, IL-10 and CXCR4 and CCR7 receptors   in a murine model of hepatocellular carcinoma (PM299L). Methods. In vitro assays were performed co-culturing murine DCs and HCC tumor line. The expression of proinflammatory cytokines (IL-12, IL- 6, IL-1β, TNF-α), immunosuppressive (IL-10) and receptors associated with migration and maturation (CXCR4 and CCR7) was evaluated by Qpcr at 24, 48 and 72 hours. The tests were repeated three times. Results. DCs exposed to the HCC tumor environment showed increased expression of proinflammatory cytokines and IL-10 compared to the control group. Furthermore, elevated expression of CXCR4 and CCR7 receptors will be observed in DCs exposed to HCC. These changes in gene expression occurred within a 72-h period of coculture. Conclusion. DC activity is influenced by HCC tumor environment and interaction time, which modulates their proinflammatory and antigen presentation function. These findings highlight the importance of understanding the dynamics of the immune response in hepatocarcinoma.
