Abstract

Aloe polymannose (AP), a high mannose biological response modifier (BRM) purified from the Aloe barbadensis Miller plant, was tested for activity in enhancing antibody titres against coxsackievirus B3 (CVB3) and CVB3-induced myocarditis in murine models of the disease. Inoculation of mice with AP over a range of three nontoxic doses and in varying schedules did not reduce virus titres in heart tissues or ameliorate virus-induced cardiopathological alterations during acute disease. However, this BRM was found to significantly enhance titres of anti-CVB3 antibodies produced during acute infection of three strains of mice with CVB3. Simultaneous intraperitoneal inoculation of AP at a dose of 0.5 mg/kg body weight per mouse with purified CVB3 significantly increased ELISA titres of anti-CVB3 antibodies and the proportion of mice with these titres, compared with similar parameters in mice inoculated only with CVB3. The data conclusively show that AP can immunopotentiate antibody production against capsid protein epitopes of a nonenveloped picornavirus and suggest this BMR (AP) might be of benefit in enhancing antibody titres against other enteroviruses during a natural infection and poliovirus vaccine strains.
