A delicate balance

Abstract: The utility of allogeneic stem cell transplantation for treating hematologic malignancies is enhanced by the graft vs. tumor (GvT) effect, but limited by graft vs. host disease (GvHD). Studies involving the inhibition of CD73 by genetic or pharmacologic means suggest that the levels of CD73-generated adenosine may be manipulated to control GvHD, while maintaining the GvT effect.

“…Mechanistically, deletion of CD73 caused increased proliferation of alloreactive CD4 + and CD8 + T cells. Consistent with this finding, endogenous adenosine binding to the A 2A -AR limited the expansion of alloreactive T cells and dampened the severity of acute GvHD [31,32]. This was consistent with the finding that activation of the A 2A -AR reduced GvHD severity [33].…”

“…In absence of CD73 and adenosine, alloreactive T cells show a stronger proliferation with increased secretion of pro-inflammatory cytokines and improved migration capacity. This more aggressive T cell phenotype translates into more pronounced GvHD severity, but also offers a target for enhancing the GvL effect in the context of allo-HCT ( 67 ).…”

“…Было показано, что генерируемый CD73 аденозин -это фактор, с помощью которого можно влиять на тяжесть РТПХ и РТПО (реакция «трансплантат против опухоли») [78,97]. РТПХ усиливается за счет АТФ, который выделяется из погибших клеток и является провоспалительным фактором, участвующим в активации антигенпрезентирующих клеток хозяина посредством P2X7-рецептора.…”

“…Внеклеточный аденозин связывается с аденозиновым A2A-рецептором донорских аллореактивных Т-клеток и ингибирует их активацию антигенпрезентирующими клетками хозяина. Ограничение аллореактивной активации Т-клеток предотвращает развитие РТПХ, но ограничивает эффект РТПО [78,97].…”
