Tumor-derived immunosuppressive factors contribute to the evasion of malignant cells from the immune response, partially by hampering dendritic cell (DC) differentiation. Here, we analyze whether soluble mediators released by the most frequent histological types of non-small cell lung carcinoma, squamous cell carcinoma (SCC), and adenocarcinoma (AD) cells, affect the development and functionality of DC. Monocytes from healthy donors were differentiated in vitro into DC with granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-4, in the absence or presence of soluble factors (SF) from SCC or AD cell lines.

Methods: We studied 11 patients who met the following inclusion criteria: (1) systemic lupus erythematosus (SLE) according to the American College of Rheumatology criteria; (2) lupus nephritis class III, IV, or V according to the World Health Organization; (3) proteinuria in the nephrotic range (> or = 3 g/24 h) for at least 6 months despite treatment. All patients received pentoxifylline 800-1600 mg/day.
