The HTLV-I antigen (Ag) was detected in short-term cultured peripheral blood mononuclear cells (PBMNC) from 44% of patients with HTLV-I-associated myelopathy (HAM), using the indirect immunofluorescence method. The HTLV-I Ag-positive cells accounted for less than 4% of cultured PBMNC in all but one case. The kinetics and mechanism of HTLV-I Ag expression in cultured cells were these studied in this individual with about 20% positive cells. HTLV-I Ag was 0.3% at 6 h after the culture and the number of positive cells increased to 9.3% at 48 h. The sera from HAM patients had a suppressive effect on the expression of HTLV-I Ag in the cultured cells. This suppression was more potent in sera from patients with a high than with low antibody titer. There were no correlations between the HTLV-I Ag expression in cultured cells and the various clinical and laboratory findings, in each case.
