Our results demonstrated that previous AD diagnosis was associated with higher levels of IL-6 in the follow-up evaluation, suggesting that the presence of anxiety in childhood could influence altered inflammatory markers.
Here we use homozygous and heterozygous transgenic mice expressing elevated levels of IL-6 in the CNS due to increased astrocyte expression and non-transgenic littermates to examine a role for astrocyte-produced IL-6 in emotionality (response to novelty, anxiety-like, and depressive-like behaviors).
On T2, self-reported doctors' empathy ability was significantly positively correlated with patient sleep and self-efficacy (P<0.01), and significantly negatively correlated with patient anxiety and IL-6 (P<0.01).
After controlling for demographic characteristics, body mass index, and depressive symptoms, attachment avoidance and anxiety were associated with IL-6 but not CRP.
Our findings thus suggested that the differential expressions of BDNF and IL-6 after CSDS may contribute to less anxiety and less despair observed in GHS-R1a-deficient mice than in WT control mice.
The changes of BPRS-E-manic and BPRS-E-anxiety scores correlated with the baseline IL-1ra (r=-0.393), IL-6 (r=-0.407), and insulin like growth factor binding protein 3 (r=-0.446).
Next, treatments with fecal microbiota of ampicillin-treated mouse (FAP), K. oxytoca, or lipopolysaccharide isolated from K. oxytoca (KL) induced anxiety and colitis in mice and increased blood corticosterone, IL-6, and lipopolysaccharide levels.
The values for the following parameters decreased in the hypertensive group post training: anxiety (-6.2 ± 2 score; 60%), Timed Up and Go test (-7.4 ± 0.3 sec; 30%), protein carbonylation (-0.15 ± 0.03 nmol/mg protein; 50%), nitric oxide (12.4 ± 6 nmol/mg protein; 62%), interleukin-6 (-27.6 ± 5.7 pg/mg protein; 46%), and tissue necrosis factor-alpha (-52.4 ± 3.8 pg/mg protein; 40%); however, the values of the following parameters increased before training: Berg score (56 ± 2; 7.8%), flexibility (27 ± 1 cm; 71%); glutathione (3.1 ± 1.3 nmol/mg protein; 138%), and superoxide dismutase (1.6 ± 0.4 nmol/mg; 166%).
Establish whether inflammatory biomarkers-serum amyloid A (SAA), C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α)-are related to key symptoms of depression, including anxiety and fatigue, in a cross-sectional, out-patient setting to identify biomarkers that reflect psychiatric symptomatology in a naturalistic, real-life population.
Migraine patients showed higher tension (p=0.019) and anxiety scores (p=0.046), TNF-α (p<0.01), and IL-12p70 (p=0.01), while IL-6 (p<0.01), IL-8 (p<0.01), and IL-10 (p<0.01) were decreased compared to control group.
The present study suggests that changes in the GSH-dependent defense system, NF-κB activation and increased IL-6 protein expression may have a role in social isolation-induced changes in a rat model of depression and anxiety, and contributes to our understanding of the mechanisms that underlie the antidepressant and anti-inflammatory activity of Flx in socially isolated rats.
However, the expression of DNMT1/3A, EZH2 and IL-6 genes increases with increasing Hospital Anxiety and Depression Scale-Anxiety scores in the anxious cohort only.
During antiviral treatment we reported that subjects with CC genotype (IL-6) presented significantly lower changes from baseline in IFN-induced depression (p=0.005) and IFN-induced anxiety (p=0.004).
