Modulation of delayed-type hypersensitivity reaction (DTH) in mice by synthetic adjuvants and the mode of their action were investigated. Intracutaneous injection of azobenzenearsonate coupled to phosphatidylethanolamine (A-PE) without adjuvant did not induce DTH. Administration of A-PE with the quaternary amines
