Immunomodulatory effect of Red Moringa oleifera Leaves Fermentation Extract on Il-21 And Il-22 Expressions in Balb/C Mice Exposed to Salmonella typhi

Interleukin-21(IL-21) and interleukin-22(IL-22) expressions in the substantial intestine increase when inflammation occurs. They can also induce the production of pro-inflammatory cytokines and Matrix Metallo Proteinases (MMP) in subepithelial fibroblasts. To evaluate at IL-21 and IL-22 expressions in BALB/c mice after administering red M. oleifera leaf fermented extracts exposed to Salmonella typhi. The expression of IL-21 and IL-22 were evaluated for immunomodulatory effect was analyzed by flowcytometer. Data were analyzed by one-way ANOVA and continued with the Tukey test (p<0.05). The results showed that the fermented extract of red M. oleifera leaves could act as an immunosuppressor characterized by decreased levels of IL-21 and IL-22 both on CD4 T and CD8 T cells in mice injected with Salmonella typhi ranging from 14 mg/Kg BW to 42 mg/Kg BW and Pyrex analysis explains that the cathecin compound has the same active side as 8MR in forming bonds with MMP-9. The results of this study provide is the fermented extract of red M. oleifera leaves decreasing the expression of CD4⁺IL21⁺, CD8⁺IL21⁺ and CD4⁺IL22⁺, CD8⁺IL22⁺ through inhibition of MMP-9.
