Circulating CD16-Positive Monocyte-like Myeloid-Derived Suppressor Cells and Intermediate Monocytes Associated with Clinical and Immunological Complications in Pars Planitis Patients.

ABSTRACT: Recently, we observed that pars planitis (PP) patients present alterations in peripheral blood (PB) Th17/Treg associated with dysregulation in the Th1 response. Yet, little is known about the systemic distribution of myeloid cells, which drive the recruitment and differentiation of the adaptive effectors toward pathogenic inflammatory Th1 and Th17 as well as regulatory lymphocytes in PP. Although myeloid populations in patients with uveitis have previously been addressed, the data did not provide an exact description of PP patients. Using flow cytometry, we evaluated monocyte and IDO-expressing monocyte-like myeloid-derived suppressor cell (MDSC) subpopulations in PB samples from 15 patients with different courses of PP (cystoid macular edema and non-macular edema subgroups; CME and nCME,
