pubmed:abstractText |
A variety of immunomodulatory effects have previously been attributed to haptoglobin (Hp). These are supposed to be partly mediated through binding of Hp to CD11b. In the present study, we assessed its effects on T-helper (Th) cytokine production following both in vitro and in vivo stimulation of T-cells. Hp exhibits a dose-dependent inhibitory effect on human T lymphocyte release of the Th2 cytokines (IL-4, IL-5, IL-10 and IL-13) in vitro, whereas it has no clear effect on Th1 cytokine (IL-2 and IFN-gamma) release. When administered an anti-CD3 monoclonal antibody, Hp knockout mice produced more IL-4 and less IFN-gamma than did their wild-type litter-mates. Our findings imply that Hp may be regarded as a regulator of the Th1/Th2 balance in both human and murine immune systems.
