Abstract excerpt
Cytotoxic T lymphocyte antigen-4 (CTLA4) suppresses cytotoxic T lymphocyte activity. We examined the associations of CTLA4 single-nucleotide polymorphisms (SNPs) at promoter site -318 and exon-1 site 49 with clearance of hepatitis C virus (HCV) after treatment with combination interferon-alpha plus ribavirin (IFN-alpha+R) therapy in 79 white sustained responders (SRs) and 79 nonresponders (NRs). SRs had higher...
