Help with references for a mouse model of macrophage deficiency?

[Stephen Gisselbrecht]

	Hi there.
	If anyone knows of a "macrophageless" mouse (or any other animal), it
would be an ENORMOUS help to me if you could e-mail me a reference.  I
will be exceedingly grateful, and I could dedicate my master's degree to
you, if you want and I wind up getting one.  IDEAL would be if there were
one that had an otherwise intact immune system *and* one that didn't, but
I'm not so naive as to think that I'm likely to get that.  I'll be
grateful for whatever information and suggestions you can offer.  Please
e-mail replies to gisselbr at husc.harvard.edu, since I can't really read
news on a regular basis right now.

	Thanks a lot.
