Abstract

OBJECTIVE:

To clarify the protective roles of compatibility of geniposide and ginsenoside (Rg1) in regulating ischemia injured microglia homeostasis by comparing the difference in regulatory roles of geniposide, Rg1, or ginsenoside + Rg1 in balancing secretion of oxygen glucose deprivation induced microglia inflammatory cytokines.

METHODS:

The mimic ischemia injured microglia model was induced by oxygen-glucose deprivation (OGD). Then geniposide, Rg1, or ginsenoside + Rg1 (Tongluo Jiunao Injection, TJI) was respectively added. The NO content was determined by Griess Reagent. The cyto activity was detected using cell count kit. Contents of TNF-alpha and TGF-beta and their expression levels were detected by ELISA and Western blot.

RESULTS:

Geniposide + Rg1 could significantly inhibit the release of NO, elevate the TGF-beta level, and decrease the content of TNF-alpha without influencing the cell survival. The two active ingredients played different therapeutic roles. The compatible use was obviously superior to use any one of the two active ingredients alone.

CONCLUSIONS:

Geniposide, Rg1, or Ginsenoside + Rg1 had regulating roles in balancing ischemia injured microglia homeostasis. Its mechanisms might be related to up-regulating the TGF-beta expression and down-regulating TNF-alpha expression.
