title: Isolation and characterization of cell clones persistently producing teardrop-shaped particles of human immunodeficiency virus type 1.
abstract: Several cell clones producing teardrop-shaped human immunodeficiency virus type 1 (HIV-1) particles were isolated from MT-4 cells that survived HIV-1 infection after extensive cell lysis. Most of the teardrop-shaped particles contained an electron-dense core structure, and the particles could replicate in MT-4 cells. No significant structural difference in the HIV-1 proteins was observed between these cell clones and the MOLT-4 cells producing intact HIV-1 particles, although their envelope structure is morphologically abnormal.
