Matrix metalloproteinase 9 plays a key role in lyme arthritis but not in dissemination of Borrelia burgdorferi.

abstract：:A battery of lymphoid and nonlymphoid cells was examined for susceptibility to lysis by natural killer cells of chickens. Several susceptible targets were recognized, and most susceptible among these were cells of line LSCC-RP9, derived from a lymphoid tumor induced by Rous-associated virus 2.
