title: Detection of the binding of IgG2a and IgG2b on the surface of macrophages from mice chronically infected with lactic dehydrogenase virus.
abstract: This study showed that sera from mice chronically infected with lactic dehydrogenase virus (LDV) contained virus-antibody complexes (IC). IgG2a and IgG2b, but not IgG1, IgG3, IgM or IgA, were demonstrated on the surface of macrophages from chronically infected mice. These results suggest that IC in the circulation may bind to Fc receptors for IgG2a and IgG2b on the surface of macrophages and lead to the modulation of macrophage function seen in chronically LDV-infected mice.
