CD163 and AIDS dementia complex: Importantly, increased accumulation of fibrocytes (CD45+Col1+CCR2+CD44+CD163+CD162+) was observed in tumor tissue of all lung cancer types, including non-small cell lung carcinoma (adenocarcinoma (ADC), adenosquamous cell carcinoma (ADSCC), mucous adenocarcinoma (MADC), papillary adenocarcinoma (PADC), and squamous cell carcinoma (SCC), as compared with healthy lung tissues (Fig. 4A, B).
