CD1a and CD83 expression. (A) CD1a and CD83 immunostaining in both NSCLC tissues and peritumoral lung tissues. Magnifications are indicated. (B) Mature (i.e. CD83+) DC infiltration in NSCLC with low (below median) or high (above median) GM3 or pSTAT3 expression. (C) Compartmentalization of immature (CD1a+) and mature (CD83+) DCs as determined by their infiltration in peritumoral lung tissue or NSCLC tissue. NSCLC, non-small cell lung cancer.
