Figure 2. Depletion of Btk inhibits macrophage production of homeostatic chemokines and angiogenic cytokines.
(A & B) THP-1 differentiated macrophages were transfected with Btk siRNA for 48 hours and then stimulated with LPS (1 μg/ml) for 18 hours. The chemokine and cytokine production from macrophages were measured by ELISA. (C) Total RNA was extracted, and the expression of mRNA was detected by real time PCR. *Significantly decreased compared to LPS treatment alone (p < 0.05). Results are representative of three similar experiments.
