Magnitude of the host innate alloresponse is influenced by the genetic background of the donor. Magnitude of the host innate alloresponse is influenced by the genetic background of the donor. Bone marrow plugs from different donors were transplanted individually under the kidney capsules of separate mice (A) or simultaneously in the contralateral kidneys of the same mouse (B and C). All recipients were BRG unless otherwise stated. Donor strains are shown on the x axis. The number of recipient mono-DC infiltrating the grafts was determined 1 week later as a measure of an innate alloresponse. (A) Responses of BRG recipients to allografts from six common (DBA.2, NOR, C3H, FVB, BALB/c, and NOD) and three wild-derived (Pahari, WSB, and CAST) inbred strains. Statistical significance shown is relative to B6. (B) NOD grafts transplanted to syngeneic NRG mice (NOD to NRG) elicit a much weaker response than NOD grafts transplanted to allogeneic BRG mice (NOD to BRG). (C and D) Innate responses elicited by grafts from distinct donors transplanted under the contralateral kidney capsules of the same BRG recipient (C) or CRG recipient (D). n = 5 to 6 mice per group per experiment. Experiments were performed once or twice. Each dot represents an individual biological replicate. Bars are means. **P < 0.01, ****P < 0.0001; ns, not significant (unpaired two-tailed t test).
