title: Reactivation of antibody genes in Epstein-Barr virus transformed human B cell lines. A preliminary report.
abstract: Three immortalised human B cell lines, which had either last their capacity to secrete specific antibody or secreted low levels of antibody were studied in an attempt to reactivate or enhance antibody synthesis. A variety of different stimuli known to cause activation, proliferation and differentiation of normal B cells were used including polyclonal activators and recombinant interferon. Four of them, (namely LPS, anti-IgM, IL2 and IL6) effectively increased specific antibody synthesis after three days of culture. These preliminary experiments show that the loss or decline in immunoglobulin production by immortalised human B cells is, at least in some cases, reversible.
