TNF-α is the most common cytokine used for activating DCs and generating mature MDDC either alone or in combination with other cytokines. Objective: To compare effects of traditional cytokine cocktail (TNF-α + IL-1β) versus TLR4-agonist monophosphoryl lipid A on the viability, phenotype, cytokine profile and functionality of MDDC. Methods: The study included 32 individuals; twenty Acute Myeloid Leukaemia (AML) cases in complete remission and 12 healthy volunteers. They were divided into 3 groups: Group 1: control group: 12 subjects to measure the baseline levels of all markers in the monocytic preparation; Group 2: cytokine cocktail (TNF-α) group, which included 10 AML subjects; Group 3: MPLA group which included 10 AML subjects. Results: TNF-α group showed higher expression of CD83 than MPLA group indicating higher capacity to induce DC maturation but both were similar in CD86, CCR7 and IL-10 expression. Preparation of dendritic cells from AML cases in remission and loading them with tumor peptides was successful. Conclusion: The effect of MPLA in DC maturation is comparable with traditional DC maturation cocktail.}, keywords = {DCs Maturation,Monocyte-Derived DCs}, url = {https://iji.sums.ac.ir/article_39284.html}, eprint = {https://iji.sums.ac.ir/article_39284_93c8bfa1ebac7e0690e7e6f4f911c298.pdf} }
