Several LAAs are expressed in CML and therefore are candidate structures for specific immunotherapies: bcr-abl (100%), G250 (24%), hTERT (53%), MPP11 (91%), NEWREN60 (94%), PRAME (62%), Proteinase3 (71%), RHAMM/CD168 (83%), and WT1 (53%), but not BAGE, MAGE-A1, SSX2, or NY-ESO-1.
IgG antibodies directed against MPP11 were also detected in 25-50% of the sera of patients with solid tumors such as melanoma, renal cell, ovarian and breast carcinoma. mRNA expression of MPP11 was detected in 20/20 AML patients and 7/10 patients with CML.
