Curcumin primed exosomes reverses LPS-induced pro-inflammatory gene expression in buffalo granulosa cells.

Abstract

Curcumin possesses anti-inflammatory properties and provides a promising treatment for inflammation. The aim of the study is to establish that buffalo granulosa cells when primed with curcumin (20 μM), release improved cellular contents through exosome that can mitigate granulosa cell dysfunction. Recently, we have shown that buffalo granulosa cells exposed to LPS (1 μg/mL) in serum free culture, transiently increased the pro-inflammatory cytokine genes (IL-1β, TNF-α, IL-6) expression followed by the inhibition of CYP19A1 gene expression and estradiol production. Therefore, LPS-treated granulosa cells were used as a model of inflammation and curcumin primed exosomes were utilized to check their potential for reducing granulosa cell dysfunction. Expression level of pro-inflammatory cytokines and CYP19A1 were detected by real time PCR while estradiol levels were measured by ELISA. Exosomes derived from curcumin-treated cells alleviated LPS mediated inflammation. In conclusion, our study potentiates the use of curcumin primed exosomes in mitigating granulosa cell dysfunction. Results show the therapeutic conservatories of curcumin via primed exosomes.
