In HR-MDS and AML, time to look closer at the dual impact of TIM-3

TIM-3 is expressed on immune cells and myeloid cells, so targeting it provides potential to activate immune response and suppress leukemic cell proliferation.1,2

HR-MDS and AML patient prognosis

Why do patients face such a difficult prognosis?

Activate immune response and suppress leukemic cell proliferation

Can the TIM-3 pathway offer potential for dual impact?

AML, acute myeloid leukemia; HR-MDS, high-risk myelodysplastic syndrome; TIM-3, T cell immunoglobulin and mucin domain-3.
