New immune strategies for the treatment of acute lymphoblastic leukemia: antibodies and chimeric antigen receptors.
The prognosis of adult acute lymphoblastic leukemia (ALL) remains poor and novel treatment strategies are needed. Antibody-based therapies represent such an approach. ALL cells express various surface antigens that are targets for monoclonal antibodies. This review focuses on 4 major classes of antibody therapy: (1) naked antibodies, (2) T-cell-engaging bispecific single-chain antibodies, (3) i...
متن کاملAnti-CD22-chimeric antigen receptors targeting B-cell precursor acute lymphoblastic leukemia.
Immune targeting of B-cell malignancies using chimeric antigen receptors (CARs) is a promising new approach, but critical factors impacting CAR efficacy remain unclear. To test the suitability of targeting CD22 on precursor B-cell acute lymphoblastic leukemia (BCP-ALL), lymphoblasts from 111 patients with BCP-ALL were assayed for CD22 expression and all were found to be CD22-positive, with medi...
متن کاملChimeric fusion karyotypes in childhood B-cell acute lymphoblastic leukemia.
Cytogenetics study using combination of conventional cytogenetics and fluorescent insitu hybridization was carried out in 171 pediatric acute lymphoblastic leukemia patients subgrouped to B-ALL (n=126) and T-ALL (n=45) by bone marrow morphology and immunophenotype. The chromosomal aberration frequency in B-ALL and T-ALL was 79% and 71%, respectively. TEL/AML1 translocation was detected in 28% o...
متن کاملExpression of ROR1 Gene in Patients with Acute Lymphoblastic Leukemia
Background: Acute lymphoblastic leukemia (ALL) results from genetic alterations in a single lymphoid progenitor cell. Expression of ROR1 is reported to be increased in ALL and mantle cell lymphoma. In this study the expression of ROR1 was assessed in newly diagnosed patients with ALL. Methods: This study was carried out on 40 patients with newly diagnosed ALL and healthy individuals as contro...
متن کاملCytotoxic T cell response against the chimeric ETV6-AML1 protein in childhood acute lymphoblastic leukemia.
Cytotoxic T lymphocytes (CTL) are potent effector cells that could provide long term antitumor immunity if induced by appropriate vaccines. CTL recognize 8-14 amino acid-long peptides processed intracellularly and presented by MHC class I molecules. A well-characterized example of a potential tumor antigen in childhood pre-B Acute Lymphoblastic Leukemia (ALL) results from the chromosomal transl...
