ABSTRACT:
The invention provides methods for modulating an immune response in a subject including, for example, administering to the subject a composition comprising an effective amount of a lymphocyte differentiation factor sufficient to modulate the immune response. In one aspect, the lymphocyte differentiation factor comprises protein A (PA).
