3.1. In Vitro Experiments
To confirm that LG2055 activates dendritic cells, we performed in vitro assays using PBMCs. PBMCs from four different donors were treated with LG2055, and the expression levels of CD86 and HLA-DR were evaluated to determine pDC and mDC activity. Increased expression of CD86 and HLA-DR was observed in three donors, whereas no increase in expression was observed in the fourth donor (
