Studies on natural cytotoxicity of human monocytes in viral hepatitis.

abstract：:Serum IgG1 levels are selectively increased in patients with chronic hepatitis C virus (HCV) infection. In 15 patients who received interferon (IFN)-alpha therapy, serum levels of immunoglobulin classes and IgG subclasses were measured during treatment and after it was discontinued. In spite of important individual va...

We previously reported that HKSC selectively enhances IgG1 production by LPS-activated mouse B cells. To determine if this IgG1 selectivity is caused by selective IgG1 class switching, we performed RT-PC...
