title: Neonatal tolerance of H-2 alloantigens. I. I region modulation of tolerance potential of K and D antigens.
abstract: By utilizing H-2 congenic strains of mice and appropriate recombinants, it has been possible to determine that Class I alloantigens (of K and D region genes) function poorly as tolerogens when inoculated into neonatal recipients. Alternatively, Class II alloantigens (encoded by I region genes) are excellent tolerogens. Moreover, Class I alloantigens are converted to good tolerogens when conjoined in the tolerizing inoculum with Class II alloantigens. The I subregions in which genes reside that mediate this tolerance-promoting effect are IJ and/or IE. It is suggested that elicitation of a suppressor mechanism, perhaps related to IJ region alloantigens, is responsible.
