BACKGROUND Immunophenotyping improves both accuracy and reproducibility of acute leukemia classification and is considered particularly useful for identifying aberrant lineage association of acute leukemia, biphenotypic and bilineal acute leukemia, as well as monitoring minimal residual disease. Some immunophenotypes correlate with cytogenetic abnormalities and prognosis. THE AIM OF OUR STUDY...
Abstract Central nervous system (CNS) involvement remains a challenge in the diagnosis and treatment of acute lymphoblastic leukemia (ALL). In this study, we identify CD79a (also known as Ig?), signaling component preB cell receptor (preBCR), to be associated with CNS-infiltration –relapse B-cell precursor (BCP)-ALL patients. Furthermore, show that downregulation hampers engraftment cells diffe...
Background and objectives: The development of new therapeutic options to treat leukemia (therapies targeting chimeric antigen receptor [CAR] T cells) down-regulates markers expressed on the cell surface. Therefore, conventional immunophenotyping panels no longer make these antigens unreliable for identifying a B immunophenotype. In our study, we methodically compared multiparametric flow cytome...
Na-ASP-2 is an efficacious hookworm vaccine antigen. However, despite elucidation of its crystal structure and studies addressing its immunobiology, the function of Na-ASP-2 has remained elusive. We probed a 9000-protein human proteome microarray with Na-ASP-2 and showed binding to CD79A, a component of the B-cell antigen receptor complex. Na-ASP-2 bound to human B lymphocytes ex vivo and downr...
To develop a practical immunohistochemistry panel for distinguishing lymphoblastic lymphoma from Ewing sarcoma (ES), we evaluated 17 ES and 27 lymphoblastic lymphoma and leukemia cases with antibodies to CD99, terminal deoxynucleotidyl transferase (TdT), leukocyte common antigen (LCA), CD43, CD79a, CD20, CD3, vimentin, and neuron-specific enolase (NSE). Three cases were bone lymphomas, 2 initia...
OBJECTIVES To assess a large series of patients with acute myeloid leukemia (AML) with t(8;21) for both IGH@ and IGK@ B-cell gene rearrangements and for expression of PAX5, OCT2, and Bob.1 by immunohistochemistry and expression of CD19, CD79a, CD20, and CD22 by flow cytometry immunophenotyping. METHODS A total of 48 cases of AML with t(8;21)(q22;q22) were evaluated by immunohistochemistry and...
A case of lymphoma of T-cell derivation with aberrant expression of three B-cell lineage markers (CD19, CD20, and CD79a), which was diagnosed on a left axillary excision, is described. Immunohistochemical studies and flow cytometry analysis demonstrated neoplastic cells expressing CD3, CD19, CD20, and CD79a with absence of CD4, CD8, CD10, CD30, CD34, CD56, CD68, TDT, MPO, PAX-5, and surface imm...
Targeting cytotoxic drugs to cancer cells using antibody-drug conjugates (ADCs), particularly those with stable linkers between the drug and the antibody, could be an effective cancer treatment with low toxicity. However, for stable-linker ADCs to be effective they must be internalized and degraded, limiting potential targets to surface antigens that are trafficked to lysosomes. CD79a and CD79b...
