CD10 | Normal lymphoid progenitors, neutrophils and blast cells of B-ALL |
Associated with favourable presenting features in paediatric B-ALL and possible target for emerging CAR-T |
CD19 | Normal and malignant B lymphocytes |
Target of blinatumomab and CAR-T |
CD20 | Normal and malignant B lymphocytes |
Target of rituximab, up-modulated in B-ALL patients with poor prognosis |
CD27 | T cells, natural killer cells and thymocytes, also memory B cells, and in some subsets of B-ALL |
Positive in B-ALL with BCR/ABL or CRLF2 rearrangement, high positivity was associated with poor prognosis |
CD34 | Pluripotent stem cells |
Lack of expression associated with worse event free and overall survival of ALL |
CD45 | Cells of hematopoietic origin |
High expression associated with high risk disease and worse event free survival, and worse rate of complete remission after the induction therapy |
CD58 | Hematopoietic and nonhematopoietic cells |
Lack of expression reduces the efficacy of blinatumomab and anti-CD19 CAR-T |
CD66c | Granulocytes and their precursors, most common myeloid antigen on malignant B lymphoblasts |
Associated with specific genetic alterations such as BCR/ABL, hypodiploidy, hypodiploidy and CRLF2-positivity in B-ALL |
CD137 | T lymphocytes and natural killer cells but also on activated B cells of naive origin |
Enhances B cell survival |
