abstract={<i>Porphyra tenera </i>has long been consumed as food in Korea and Asia. The effects of <i>Porphyra tenera </i>extracts on the immune system are largely unknown. Therefore, this study investigated the immune-stimulating effects of ethanol and water extracts of <i>P. tenera</i>. The immunomodulatory potential of <i>P. tenera </i>was evaluated by determining its effect on cell viability and cytokine expression of mouse RAW264.7 cells and splenocytes. We investigated the effect of 10% ethanol extracts of laver (<i>P. tenera</i>) on the RAW264.7 cells. Production of nitric oxide (NO) and cytokines (interleukin [IL]-1¦Â, IL-2, and IL-4, inducible NO synthase, and interferon-&#947;) in RAW264.7 macrophages was slightly higher after treatment with <i>P. tenera</i> extracts. Ethanol extracts upregulated and enhanced the functions of macrophages, such as NO and cytokines (IL-1¦Â, IL-2, and IL-4, inducible NO synthase, and interferon-&#947;) production. In addition, cytokine concentrations were significantly increased in cells treated with different doses of <i>P. tenera</i> ethanol extracts compared to the control group. Overall, the results demonstrated that <i>P. tenera</i> extracts enhanced cytokine secretion in mouse splenocytes and macrophages. From these findings, it can be concluded that <i>P. tenera</i> possess a natural compound with immune-stimulatory activity. <i>P. tenera</i> extract is a good immunostimulant from natural compounds.},
