Effects of HCP and HCP-1a on cell viability, proinflammatory cytokines, and NO concentration in RAW264.7 cells. After incubating for 24 h with increasing concentrations of HCP and HCP-1a, the cytotoxicity of cells was then determined by MTT assay (a). The levels of (b) TNF-α, (c) IL-1β, and (d) NO in the collected supernatants were measured by ELISA assay. p<0.01; p <0.05.
