Spotlight on adenosine-mediated suppression of dendritic cell function
10 / 22 / 2021
Differentiation and maturation of competent dendritic cells (DCs) is critically dependent on their microenvironment. Among factors which can, in cancer, reach high levels in the tumor microenvironment, adenosine - one of the major immunosuppressive pathways - is known to modulate the function of many cell subsets, including DCs. Adenosine receptor stimulation skews DC differentiation toward a distinct cell population which has, unlike normal myeloid DCs, tolerogenic and suppressive phenotype expressing high levels of proinflammatory and immune suppressor factors, as well as impaired allostimulatory capacity.
