title: Correlation between chemoattractant-induced leukocyte adherence inhibition, macrophage chemotaxis, and macrophage inflammatory responses in vivo.
abstract: Variations in the magnitude of inflammatory macrophage response in vivo and macrophage chemotaxis in vitro, observed among inbred mouse strains, suggest that these traits are genetically-regulated. The development of an A X B series of recombinant inbred (RI) strains of mice derived from the C57BL/6J (B, high responder) and A/J (A, low responder) resulted in the availability of a large number of new inbred strains which express a spectrum of variations in the magnitude of these traits. These strains were used in the present study as a tool to examine the possible correlation between the phenomenon of leukocyte adherence inhibition (LAI) and those of macrophage inflammatory response in vivo and macrophage chemotaxis in vitro under the assumption the LAI requires the same cellular events as chemotaxis and that LAI resembles, grossly, the accumulation of nonadherent inflammatory cells in vivo. The typing of A X B RI strains for the traits of LAI, macrophage accumulation in vitro, and macrophage inflammatory response in vivo resulted in a correlation between the magnitude of response of those three phenomena in the total of 19 inbred strains tested, thus suggesting that the chemoattractant-induced LAI is biologically related to the events that mediate macrophage chemotaxis in vitro and the macrophage inflammatory response to sterile irritants in vivo.
