AB Inactivated simian immunodeficiency virus (SIV) grown in a human T-cell
line induces protection from infection by the virus in macaques.
However, observations that immunization with uninfected human T cells or
with SIV-1 prepared in human T cells can also induce protection, has
raised the possibility that protective antigens could be of human
cellular origin. Sera from animals immunized with fixed infected and
uninfected human T cells, as well as from animals immunized with
partially purified cell-free SIV have been examined for their ability to
bind to human and macaque peripheral blood mononuclear cells (PBMC) and
to-components present in fetal calf serum (FCS) in which the cells were
grown. Analysis by flow cytometry suggests that antibodies to human cell
surface antigens can be elicited with both inactivated SIV grown in
human T cells and by uninfected T cells. There was a significant
association between the presence of anti-cell antibodies and protection
from infection. However, anti-cell surface antibodies were not detected
with macaque mononuclear cells by flow cytometry or by
immunoprecipitation, unless these cells were first treated with FCS or
activated by a mitogen. Immunoprecipitation of resting human PBMC with
sera from immunized animals suggests the presence of antibodies to class
I heavy and light chains [beta 2-microglobulin (beta 2 m)] and to bovine
beta 2m, which may originate in FCS used to grow the cell line.
Antibodies to CD4 were also found in sera from animals immunized with
SIV grown in human T cells. We suggest that human cellular components
augmented by FCS elicit anti-class I heavy chain, beta 2m, CD4 and FCS
antibodies which may be responsible for protection against SIV infection
in macaques.
