c-Fos protein was shown essential for an optimal transactivation of the HIV-1 long terminal repeat ( LTR ) by Tat : incubation of Jurkat cells with antisense, but not sense, c-fos oligonucleotides significantly reduced either the Tat -enhanced expression of an LTR-CAT reporter construct or the levels of gag p24 in the culture supernatants of Jurkat cells and PBMC acutely infected with HIV-1 .
