Production of cytokines from macrophages with different treatments. Secretion of (A) IL-6, (B) TNF and (C) IL1-β from macrophages with different treatments. The cells were treated with LPS, LPS+NP or LPS+rapamycin particles. Cells with no treatment were used as a control. *P<0.05 and **P<0.01. IL, interleukin; TNF, tumor necrosis factor; LPS, lipopolysaccharide; Rapa, rapamycin; NP, empty particles.
