AB PCR-in situ hybridization (PCR-ISH) was developed and utilized to
determine the distribution of human T-cell lymphotropic virus type 1
(HTLV-1) tax proviral DNA in peripheral blood lymphocytes (PBL) from
patients with HTLV-1-associated myelopathy/tropical spastic paraparesis
(HAM/TSP). PCR-ISH of HTLV-1 tax DNA in PBL from patients with HAM/TSP
revealed that 1 in 5,000 to 1 in 10,000 PBL contained virus. PCR-ISH was
sensitive, because a positive signal was consistently demonstrated from
the HTLV-1-infected cell lines HUT-102 (which contains four to six
copies of HTLV-1 proviral DNA per cell) and MT-1 (which contains one to
three copies of HTLV-1 proviral DNA per cell). Also, intracellular
amplification by PCR-ISH significantly increased sensitivity compared
with conventional ISH and was shown to be specific for HTLV-1 tax DNA.
These results are in contrast to solution-phase PCR amplification in
which greater than 1% of cells were estimated to be infected. The
discordance between these results is discussed and may indicate that
more than one copy of HTLV-1 tax proviral DNA is present in an
individual PBL.
