I would be inclined to be cautious over drawing parallels between mouse and
human IgG subclasses. My reasoning is quite simple. It is clear from an
analysis of the gene organisation and the gene and protein sequences that
the subclasses of IgG in mouse and human have arisen independently.
The numbers of IgG subclasses vary from species to species so there is
really no valid scientific argument to assume parallels between
IgG subclasses for distantly related mammalian species such as rodents and
primates.
