An object of the present invention is to efficiently suppress the function of gap junction, which is known to be involved in intercellular communication, and to use it for prevention, improvement, treatment and prevention of disease condition deterioration due to enhanced gap function. A potential inhibitor of intercellular communication is provided. SOLUTION: A glycosaminoglycan having a sulfate group having a basic skeleton of a repeating disaccharide structure (a so-called chondroitin skeleton) consisting of a galactosamine residue and a hexuronic acid residue as an active ingredient of an intercellular communication inhibitor. use.
