  • Title: Genetic control of delayed-type hypersensitivity in mice to Salmonella antigen.
    Author: Cho N, Saito-Taki T, Nakano M.
    Journal: Int Arch Allergy Appl Immunol; 1986; 81(1):24-30. PubMed ID: 3527991.
    Abstract:
    Genetic restriction on the expression of delayed-type hypersensitivity (DTH) to Salmonella typhimurium in mice transferred passively with immune spleen cells was studied. After the intravenous transfer of immune C3H/HeJ (H-2Ik) cells into A.TL (H-2Ik) or A.TH (H-2Is) mice, footpad DTH responses could be evoked in the A.TL recipients, but not in the A.TH mice. When the immune cells of BALB/c or C3H/He mice were intravenously-transferred into F1 hybrids produced by mating BALB/c and C57BL/6 or C3H/He and C57BL/6, respectively, no DTH response could be evoked in these F1 hybrids that received immune parental cells. Local transfer as well as systemic intravenous transfer of immune parental cells to F1 haplotype recipients did not cause any DTH. Previous treatment of the F1 hybrid recipients with cyclophosphamide did not result in the expression of the DTH response. Transfer of immune F1 spleen cells into parental strains also did not induce DTH. When the immune cells of parental strains were transferred into F2 mice and into back-cross mice, examination of the DTH response in these mice showed that some of them did not have any obvious footpad swelling, while others revealed various magnitudes of swelling. The resistance of F1 hybrids to transfer of DTH is discussed.
