Dynamics of T-Cell Responses and Memory T Cells during Primary Simian Immunodeficiency Virus Infection in Cynomolgus Macaques

Cynomolgus Macaques with Latent Changes in T Cell Cytokine Responses in Simian Immunodeficiency Virus-Induced

CD4+ CCR5+ T-cell dynamics during simian immunodeficiency virus infection of Chinese rhesus macaques.

Simian immunodeficiency virus (SIV) infection of rhesus macaques (RMs) provides a reliable model to study the relationship between lentivirus replication, cellular immune responses, and CD4+ T-cell dynamics. Here we investigated, using SIVmac251-infected RMs of a Chinese genetic background (which experience a slower disease progression than Indian RMs), the dynamics of CD4+ CCR5+ T cells, as th...

Emergence and kinetics of simian immunodeficiency virus-specific CD8(+) T cells in the intestines of macaques during primary infection.

In this report, three Mamu-A*01(+) rhesus macaques were examined to compare the emergence of simian immunodeficiency virus (SIV)-specific CD8(+) T cells in the intestines and blood in early SIV infection using a major histocompatibility complex class I tetramer complexed with the Gag(181-189) peptide. Fourteen days after intravenous inoculation with SIVmac251, large numbers of SIV Gag(181-189)-...

Specific CD8+ T cell responses correlate with control of simian immunodeficiency virus replication in Mauritian cynomolgus macaques.

Specific major histocompatibility complex (MHC) class I alleles are associated with an increased frequency of spontaneous control of human and simian immunodeficiency viruses (HIV and SIV). The mechanism of control is thought to involve MHC class I-restricted CD8(+) T cells, but it is not clear whether particular CD8(+) T cell responses or a broad repertoire of epitope-specific CD8(+) T cell po...
