Implication

Analyzing CXCR4-tropic HIV-1 infection in immunocompetent owl monkeys, indicating potential for new research avenues.

Key Points

To establish an immunocompetent model for studying CXCR4-tropic HIV-1 infection in owl monkeys.
Genetic characterization of 191 owl monkeys
Functional testing of CD4 and Tetherin
Analysis of HIV-1 genome changes
Observation of virus replication and viremia
Owl monkeys can be infected with CXCR4-tropic HIV-1 virus
Establishment of a durable set point viremia is observed
Seroconversion and formation of a viral reservoir occur
Virus retains 93% wildtype HIV-1 sequence
