Abstract

SIV infection of rhesus macaques has become a valuable model for the development of AIDS vaccines and antiretroviral therapies. Polymorphisms in the rhesus macaque TRIM5α gene can affect SIV replication, making it necessary to genetically screen macaques for TRIM5α alleles that are permissive for SIV replication. This limits the pool of animals that can be used in a study, thereby making the acquisition of animals needed to fulfill study parameters difficult. We have constructed a viral clone that induces neuroAIDS in rhesus macaques regardless of their TRIM5α genotype, while also highlighting the important role the disordered linker domain plays in viral infectivity.
