Massive CD8 T cell response to primary HIV infection in the setting of severe clinical presentation.

Massive CD8 T cell response to primary HIV infection in the setting of severe clinical presentation.

Acute HIV-1 infection causes a rapid total body depletion of CD4(+) T cells in most individuals and HIV-1-specific CD8(+) T cell expansion in response to viral replication. A numerically high CD8 T cell response may indicate limited T cell repertoire against HIV and rapid progression. We present a d...

Ամփոփում:Acute HIV-1 infection causes a rapid total body depletion of CD4(+) T cells in most individuals and HIV-1-specific CD8(+) T cell expansion in response to viral replication. A numerically high CD8 T cell response may indicate limited T cell repertoire against HIV and rapid progression. We present a detailed evaluation of an acutely infected individual with a strong HIV-1-specific CD8 T cell response targeting multiple epitopes demonstrating that the upper limit of CD8 expansion in this setting may be much higher than previously reported and was likely driven by the narrow HIV-specific response.
