This study investigated the potential effects of Bryophyllum pinnatum leaves with ethanol extract in decreasing percentages of maturation, increasing percentages of apoptosis, and decreasing NF-¦ÊB p65 expressions of SLE BALB/c mice B cells. Methods: Culturing B cells from pristane induced SLE BALB/c mice¡¯s spleen will resulted in this in vitro study. B cells were activated by BAFF, LPS, IL-4, and anti-CD40 yielding CD19+ >80%. B cells were cultured by adding those stimulants with and without B. pinnatum leaves (0, 0.02, 0.1, or 0.5 ¦Ìg/ml) for 72 hours at 37¡ãC. Flow cytometry was performed to determine The Percentages of maturation (CD19+CD38+) and apoptosis (Annexin V+PI+) of B cells. Further analysis to determine the expressions of transcription factor of maturation and apoptosis of B cells, NF-£¿B p65, were performed using immunocytochemistry. Data were analyzed using SPSS version 22. Results: Flow cytometry assay showed significant decrease in percentages of maturation of B cells in all doses and significant increase in percentage of apoptosis of B cells in dose 0.5 ¦Ìg/ml. Immunocytochemistry results showed significant decrease expressions of NF-£¿B p65 in all doses. Percentages of maturation, apoptosis, and expressions of NF-£¿B p65 of B cells were significantly correlated. Conclusion: This in vitro study revealed that B. pinnatum leaves with ethanol extract decreased the percentages of maturation, increased the percentage of apoptosis, and decreased NF-¦ÊB p65 expressions of SLE BALB/c mice B cells significantly %K B cells %K Bryophyllum pinnatum %K pristane %K SLE %U http://mji.ui.ac.id/journal/index.php/mji/article/view/1899
