TLDR
Virus production was associated with impaired proliferation, modulation of T3-T4 cell markers, and the appearance of cytopathic effects, providing evidence for the involvement of LAV in AIDS.Abstract:
Lymphadenopathy associated virus ( LAV ) has been isolated from patients with the acquired immunodeficiency syndrome (AIDS) or lymphadenopathy syndrome. Since the immune deficiency in AIDS seems to be primarily related to the defect of the helper-inducer T lymphocyte subset, the possibility that LAV is selectively tropic for this subset was investigated. Fractionation of T lymphocytes was achieved by cellular affinity chromatography with monoclonal antibodies. In a hemophilic patient who was a healthy carrier of LAV , reverse transcriptase activity and virus particles detected by electron microscopy were found only in cultures of helper-inducer lymphocytes. When infected with LAV in vitro, lymphocyte subsets from normal individuals yielded similar results. Virus production was associated with impaired proliferation, modulation of T3-T4 cell markers, and the appearance of cytopathic effects. The results provide evidence for the involvement of LAV in AIDS.read more

Production of acquired immunodeficiency syndrome-associated retrovirus in human and nonhuman cells transfected with an infectious molecular clone.

TL;DR: In this paper, an infectious molecular clone of acquired immunodeficiency syndrome-associated retrovirus was constructed, and upon transfection, this clone directed the production of infectious virus particles in a wide variety of cells in addition to human T4 cells.

T-lymphocyte T4 molecule behaves as the receptor for human retrovirus LAV
David Klatzmann,Eric Champagne,S. Chamaret,Jacqueline Gruest,Denise Guetard,Thierry Hercend,Jean Claude Gluckman,Luc Montagnier +7 more
TL;DR: Preincubation of T4+ lymphocytes with three individual monoclonal antibodies directed at the T4 glycoprotein blocked cell infection by LAV, strongly support the view that a surface molecule directly involved in cellular functions acts as, or is related to, the receptor for a human retrovirus.

Site-restricted persistent cytomegalovirus infection after selective long-term depletion of CD4+ T lymphocytes.
TL;DR: The CD8+ effector cells raised in the CD4 subset- deficient host were able of clear vital tissues from productive infection and to restrict asymptomatic, persistent infection to acinar glandular epithelial cells in salivary gland tissue.

Isolation of a T-lymphotropic retrovirus from a patient at risk for acquired immune deficiency syndrome (AIDS).

TL;DR: From these studies it is concluded that this virus as well as the previous HTLV isolates belong to a general family of T-lymphotropic retroviruses that are horizontally transmitted in humans and may be involved in several pathological syndromes, including AIDS.

TL;DR: The number of these particle-associated proteins is consistent with the expected proteins of a retrovirus, but the sizes of some are distinct from those of most known retroviruses of the primate subgroups.

TL;DR: A cell system was developed for the reproducible detection of human T-lymphotropic retroviruses (HTLV family) from patients with the acquired immunodeficiency syndrome (AIDS) or with signs or symptoms that frequently precede AIDS (pre-AIDS), and it provides large amounts of virus for detailed molecular and immunological analyses.
