Since there are more Tregs in NSCLC patients than in healthy people (29) and our data indicate that coculture with NSCLC cells elicits the development of lin−CD1c+CD205+ DCs (Figure 2A), NSCLC cells may facilitate the differentiation of Tregs via modulating the development of lin−CD1c+CD205+ DCs in vivo. Here, LY75 is linked to non-small cell lung carcinoma.
