Research Abstract |
To examine immunomodulating activity of galectin-9, the inducibility of HLA-DRCD33+myeloid derived suppressor cells (MDSCs) and dendritic cells (DC) in peripheral bloodmononuclear cells (PBMC) by galectin-9 were compared between healthy volunteers group(HV group) and patients with lung diseases group (LD group). Culture of PBMC withgalectin-9 exhibited the induction of MDSCs, there was no difference between those groups.In the absence of galectin-9, percentage of cultured plasmacytoid DC (pDC) and myeloidDC (mDC) in patients with sarcoidosis were lower than those in HV group. In the presencewith galectin-9, suppression of pDC induction and enhancement of mDC induction wereobserved in both groups. These findings indicated that galectin-9 induced differentialresponses in subtypes of DC.
