Fig. 2From: The impact of Hyssop (Hyssopus officinalis) extract on activation of endosomal toll like receptors and their downstream signaling pathwaysProtein expression levels of cytokines. The expression levels of IFN-α and β, IL-1β, TNF-α and IL-8 proteins were quantitatively assessed by ELISA test in PBMCs treated with 40 µg/ml Hyssop extract in comparison to the control after 12, 24 and 48 h. The experiment was performed in triplicate. Data are presented as mean ± standard division (SD). P < 0.05 was considered as statistically significantBack to article page
