H. Fang et S. Pincus, Spontaneous activation of human immunodeficiency virus type 1 in an immunotoxin-resistant variant T cell line, AIDS RES H, 15(15), 1999, pp. 1345-1349
We have previously used immunotoxins to select for HIV-1 variant cells that
transcribe HIV at extremely low levels and fail to produce HIV proteins. F
urther observation of one of these variants (E9) demonstrated spontaneous i
n vitro activation of HIV production, The mechanism of activation is differ
ent from that of U1 and ACH-2, two other cell lines that can be activated t
o express HIV in vitro.
