Opis

General description

Expression of BOB.1/OBF.1 is restricted largely to mature B-cells. Germinal center B-cells normally demonstrate strong staining for BOB.1, as do mantle-zone B-cells, and plasma cells.[1] Analyses of BOB.1/OBF.1 expression in a variety of established B-cell lines representing different stages of B-cell development has suggested a constitutive, B-cell-specific expression pattern. Because they are germinal center derived, L&H cells in nodular lymphocyte predominant Hodgkin lymphoma are consistenty immunoreactive for BOB.1. Conversely, the Hodgkin/Reed- Sternberg cells in classical Hodgkin lymphoma either do not express both (80%) or express only one (20%) of the two proteins.[1][2][3][4][5] In B-cell lymphomas, the highest expression levels for BOB.1/OBF.1 are reported in follicular center lymphomas[6][7], diffuse large B-cell lymphomas[8][9] and Burkitt lymphomas.[9]B-CLL, MALT-type, and mantle cell lymphomas score negative or display an heterogenous/weaker reactivity.10-11 Studies have suggested that anti-BOB. has a high predictive value in discriminating primary mediastinal B-cell lymphoma from classical Hodgkin disease.[10][11]Approximately 50% of acute myeloid leukemias express BOB.1.[12]
