His CD4 percentage is 33%, a slight decline from 1998 values of 38% to 40%. His CD4/CD8 ratio is 1.5. He is coinfected with hepatitis C virus (HCV), and an abdominal ultrasound shows moderate ...

Advances in single-cell immune profiling now allow simultaneous analysis of CD8+ T cell transcriptomes and TCR repertoires, revealing cellular heterogeneity, clonal dynamics, and functional ...
