Previously I had posted to this group asking for review article on IgG
subclasses. Although I received some useful replies, I realized later
that I should have been more specific.
The article that prompted my post concerned IgG subclass responses to
the E7 protein of HPV 16. (full reference below) They found that
women with IgG2 antibodies to this antigen cleared their cervical
infection. They conclude that this indicates a Th1 response is
protective against human papilloma virus.
My questions are 1) is this subclass difference well worked in human
responses? 2) are their other diseases where this subclass difference
has been observed? 3) and finally do this subclasses have any special
role in mucosal immunology?
