Syngeneic sensitization of mouse lymphocytes on monolayers of thyroid epithelial cells: IV. Correlation with H-2 haplotypes

In vitro primary syngeneic sensitization on monolayers of thyroid epithelial cells was performed with 21 inbred strains of mice representing 11 original H-2 haplotypes. Significant differences in the proliferative responses, assessed by thymidine uptake, were found to be related to the major histocompatibility complex haplotype. This result was further confirmed using congenic resistant strains of mice. In comparison with the experimental autoimmune thyroiditis induced by syngeneic thyroglobulin and adjuvant, primary syngeneic sensitization on monolayers of thyroid epithelial cells appeared to be under the same genetic control (H-2^k strains being good responders, while H-2^b mice are poor responders).
