T cells undergo enhanced apoptotic cell death when cultured with IFN-α-DCs from pregnant HA
women. IFN-α-DCs were co-cultured with 1 × 105 allogenic MNCs from healthy donors at a 1:10 ratio. After 3 days, apoptosis was evaluated by flow cytometry. Gated CD3+CD4+ T cells were analyzed for Annexin V and PI double positivity. Representative cases of untreated MNCs (left), MNCs co-cultured with IFN-DCs from normal pregnant (NP) women (middle), and MNCs co-cultured with IFN-α-DCs from pregnant women with (HA) hyperandrogenia (right) are shown.
