Fig. 6From: Alterations of monoamine neurotransmitters, HPA-axis hormones, and inflammation cytokines in reserpine-induced hyperalgesia and depression comorbidity rat modelReserpine-induced changes in serum cytokines. A The model group showed increased IL-1β level. B The model group showed increased IL-6 level. C No significant difference existed in concentration of TNF-α level. D No significant difference existed in concentration of IFN-γ level. E No significant difference existed in concentration of IL-4 level. F The model group showed decreased IL-10 level. Data is expressed as the mean ± SD. *p < 0.05, **p < 0.001, compared with their respective control groupBack to article page
