Unlike the present study in which AML-M3 cases had a higher expression of TLR2 and TLR4 compared with non-M3 AML patients, in the study by Rybka et al. the higher expression of TLR2 and TLR4 was found more in patients with myelomonocytic and monoblastic acute leukemia than in other types of AML24. Here, TLR2 is linked to acute myeloid leukemia.
