Интересно, кстати, что в 2003 году американский иммунолог Дейл Умэцу показал, что гепатит A, возбудитель которого – единственный вирус, для которого была показана связь со снижением заболеваемости аллергиями и астмой, может непосредственно уничтожать T-клетки второго типа, склонные вызывать развитие этих расстройств.
