AB We have compared the immunoglobulin isotype and IgG subclass and the
titre of neutralizing antibody responses to the human T cell
lymphotropic virus type I (HTLV-I) between a group of asymptomatic
HTLV-I infected individuals and a group with the neurological disease
HTLV-I associated myelopathy/tropical spastic paraparesis (HAM/TSP). A
western blot titration assay and an envelope peptide ELISA were used to
determine the presence and titre of isotype and IgG subclass responses
to the gag p19 and p24 proteins and to the envelope protein. Significant
increases were observed in the number of individuals seropositive for a
particular isotype and IgG subclass in the HAM/TSP group versus the
asymptomatic group particularly for IgM and IgE and to a lesser extent,
IgA. The predominant IgG subclasses to the HTLV-I p19, p24 and envelope
proteins were IgG1 and IgG3. This finding was also observed in the
titres of the antibody responses to these HTLV-I proteins. The HAM/TSP
group also exhibited significantly higher neutralizing antibody titres
than the asymptomatic group. This evidence suggests that some form of
chronic immune stimulation might be involved in the immunopathogenesis
of HAM/TSP. In addition, by following the Western blot titre to the IgM
and IgE isotypes in particular, it may be possible to identify
asymptomatic individuals progressing to HAM/TSP.
