Application
TAK-779 has been used to inhibit CC chemokine ligand 5 (CCL5)– C-C chemokine receptor type 5 (CCR5) interaction in vitro in natural killer (NK) cytotoxicity assay. It has also been used as a blocker of CCR5 to study its effects and to evaluate the opening of the Panx-1 channels on peripheral blood mononuclear cells (PBMCs) isolated from human immunodeficiency virus (HIV)-infected individuals.
Biochem/physiol Actions
TAK-779 inhibits human immunodeficiency virus (HIV) entrance by blocking the C-C chemokine receptor type 5 (CCR5). It also impairs the formation of atherosclerotic lesions by preventing T-helper 1 cells from entering the plaque. TAK-779 possesses anti-immunogenic properties. In an arthritis model, it could prevent the inflow of CCR5- and chemokine (C-X-C motif) receptor 3 (CXCR3)-positive T cells into inflamed joints. In mice, TTAK-779 protects the brain from focal cerebral ischemia.
TAK-779 is a potent, dual antagonist at chemokine receptors C-C chemokine receptor type 2 (CCR2) and C-C chemokine receptor type 5 (CCR5) with IC50 = 1.4 nM at CCR5 and 2.3 nM at CCR2. Antagonists of both CCR2 and CCR5 such as TAK-779 have been investigated for treatment of viruses, rheumatoid arthritis, multiple sclerosis, and cancer. CCR5 is particularly targeted for anti-HIV therapy, since HIV entry into cells requires chemokine coreceptors CCR5 and C-X-C motif chemokine receptor 4 (CXCR4).

Intravital imaging emerged as an indispensible tool in biological research, and a variety of imaging techniques have been developed to noninvasively monitor tissues in vivo. However, most of the current techniques lack the resolution to study events at the single-cell

The mechanism by which strictly CCR5 using HIV-1 clade C variants exacerbate disease progression in absence of coreceptor switch is not clearly known. We previously reported HIV-1 clade C envelopes (Env) obtained from late stage Indian patients with expanded coreceptor

Through the use of chimeric CXCR4/CCR5 receptors we have previously shown that CCR5-tropic (R5) HIV-1 isolates acquire a more flexible receptor use over time, and that this links to a reduced viral susceptibility to inhibition by the CCR5 ligand RANTES.

HIV CCR5 antagonists select for env gene mutations that enable virus entry via drug-bound coreceptor. To investigate the mechanisms responsible for viral adaptation to drug-bound coreceptor-mediated entry, we studied viral isolates from three participants who developed CCR5 antagonist resistance during
