In this study, we show that Tat- HIV-1 with wild-type LTRs can replicate in HeLa cells , and the virus produced from HeLa cells can infect primary peripheral blood lymphocytes and macrophages .
 ( cell type: macrophages, None) , ( cell line: HeLa cells, None) , ( DNA: wild-type LTRs, None) , ( cell type: peripheral blood lymphocytes, None) , ( cell line: HeLa cells, None)
