Bispecific molecules cross-linking ITIM and ITAM for therapy

摘要

The invention includes bispecific molecules capable of cross-linking ITAM and ITIM receptors on a cell in order to inhibit cell activation, as well as gene therapy approaches using nucleotides encoding such bispecific molecules for expression in vivo. One example of an ITAM/ITIM receptor pair is FcepsiFRI and HM18, and another is FcepsiFRI and FcgammaRII. Cross-linking of these receptors with a bispecific molecule of the invention would lead to inhibition of the release of allergic mediators and amelioration of the symptoms of allergic diseases.
