Wasn't there an article in Science a year or two ago that demonstrated
perpetuation of memory T-cells thru low level activation by cross-
reactivity. I believe this was accomplished by transferring antigen
activated T-cells to mice which did not express the antigen. I can't
recall the authors or the exact model, however.
