The results show that whey peptides has the effects on the immune regulatory; can slightly enhance the mouse monocyte-macrophage system function, mice with mild non-specific enhancement of immune function,whey peptide can inhibit the immune SRBC hemolysin antibodies, inhibition of specific humoral immune function in mice; can inhibit the proliferation of lymphocytes, inhibition of specific cellular immune function in mice; and could inhibit the role of passive cutaneous anaphylaxis.
