Abstract:
Objective:To investigate the effect of EBV protein on the production of Immunoglobulin(Ig)by cultured B cells.Methods:The purified human umbilical blood B cells were treated respectively with UV and Heat-inactivated EBV and cultured in complete IMDM. CD5, CD3, CD4 and CD8 cells were measured by flow cytometric analysis. IgG and IgM in the supernatant were detected by ELISA. At the mean time, IgG and IgM in the supernatant of cultured EBV-transformed B lymphocytes were detected by ELISA,and compared with that of UV-inactivated EBV group at the same period.Results:In UV-inactivated EBV group,CD3, CD4 and CD8 T cells couldn’t be detected,CD5 + cells occupied about 42% of all detected cells at the 14th day; and at the 28th day, 47%.The IgG A value of the 10th、18th、22th and 26th day in UV-inactivated EBV group have a significant difference compared with that in the control group ( P
