Dear Mike,

Thanks for your comments.  Your point is taken and of course is quite
correct, however perhaps I should phrase my question differently: is
there a human IgG subclass that is preferentially induced in the context
of a Th1-type microenvironment?  Such a class exists in the mouse.

Thanks,
Ian.
