骨髓活检示:浆样细胞数量增加(约70%),Kappa阳性,Lambda阴性,CD20阴性,CD38和CD138阳性,考虑浆样细胞增生性肿瘤,不能排除浆样细胞白血病的可能,请结合临床及遗传学检查。 免疫组化:MPO、CD15粒系(+),E-cad红系(+),CD42b巨核系(+)、CD3(T细胞+)、CD20(个别...
The amounts of IgG in the culture supernatants were measured by ELISA.ResultsFACS analysis of whole blood samples revealed that the proportion of CD38+IgD+ B cells among whole B cells, which represent an activated and differentiated B cell subset, was significantly higher in pSS patients than ...
We have identified and isolated a subpopulation of IgD+ B cells (IgD+CD38+ B cells) from human tonsils which expresses the germinal center (GC)-associated surface markers CD10, CD38, CD75, CD77 and Cd95/Fas. The heterogeneity of expression of several markers on IgD+ CD38+ B cells sugges...

Plasmodium falciparum infection leads to alterations in B cell subset distribution. During infancy, development of peripheral B cell subsets is also occurring. However, it is unknown if infants living a malaria endemic region have alterations in B cell s

抗免疫球蛋白D抗体(anti-immunoglobulin D antibody,抗IgD抗体)一直以来主要作为工具药来研究正常B细胞上的膜结合型IgD(membrane IgD,m IgD).最新研究表明,在病理状态下,抗IgD抗体可以通过选择性清除成熟B细胞,降低自身抗体的水平,抑制B细胞上B细胞活化因子(B cell activating factor belonging to the TNF family,BAF...
