Contribution of monocytes to viral replication in macaques during acute infection with simian immunodeficiency virus.

abstract：:In this study, the relationship between biological phenotypes, coreceptor usages, and sequence patterns of V1V2 or V3 regions on HIV-1 envelope gp 120 was carefully analyzed based on the existing isolates in the Los Alamos National Laboratory sequence database. Obviously, SI/NSI phenotypes were closely linked to the c...
