Research Abstract

Immunoglobulin superfamily cell adhesion molecules (IgCAM) and Proto-cadherin family members (Pcdh) play important roles in the neural network formations. These member proteins have the interaction systems of hemophilic binding and heterophilic bindings to not only various cell adhesion proteins but also many extra cellular proteins (ECMs). IgCAMs and Pcdh were regulated by the expression of chondroitin sulfate proteoglycans especially. We generated the knockout mice of the enzymes involved in the synthesizing of chondroitin sulfate. The expression pattern of IgCAMs and Pcdh were perturbed in the developmental stages of brain formation.
