The effects of Phycocyanobilin on experimental arthritis involve the reduction in nociception and synovial neutrophil infiltration, inhibition of cytokine production, and modulation of the neuronal proteome.

Introduction: The antinociceptive and pharmacological activities of C-Phycocyanin (C-PC) and Phycocyanobilin (PCB) in the context of inflammatory arthritis remain unexplored so far. In the present study, we aimed to assess the protective actions of these compounds in an experimental mice model that replicates key aspects of human rheumatoid arthritis.

Methods: Antigen-induced arthritis (AIA) was established by intradermal injection of methylated bovine serum albumin in C57BL/6 mice, and one hour before the antigen challenge, either C-PC (2, 4, or 8 mg/kg) or PCB (0.

Brain-enriched MicroRNA-184 is downregulated in older adults with major depressive disorder: A translational study.

Changes in microRNAs (miRNAs) expression have been described in major depressive disorder in young and middle-aged adults. However, no study has evaluated miRNA expression in older adults with major depression (or late-life depression [LLD]). Our primary aim was to evaluate the expression of miRNAs in subjects with LLD.

Epidermal growth factor and fibroblast growth factor-2 circulating levels in elderly with major depressive disorder.

Epidermal growth factor (EGF) and Fibroblast Growth Factor-2 (FGF-2) are growth factors involved neuronal growth and synaptic plasticity. These markers have been implicated in neuropsychiatric disorders, including major depression. However, no particular studies of EGF and FGF-2 have been conducted in older adults with major depressive disorder (MDD).

Soluble tumor necrosis factor receptors are associated with severity of kidney dysfunction in pediatric chronic kidney disease.

Background: In adult chronic kidney disease (CKD) patients, there is a positive association between inflammation and progressive renal dysfunction. Higher levels of soluble receptors of tumor necrosis factor (sTNFR) have been related to worst prognosis of adult CKD patients. Therefore, the present study aimed to evaluate soluble TNF receptors in children and adolescents with CKD and to search for an association with clinical and laboratory features.

Inhibition of the dopamine transporter as an animal model of bipolar disorder mania: Locomotor response, neuroimmunological profile and pharmacological modulation.

Inhibition of dopamine transporter (DAT) by GBR12909 has been proposed as a pharmacological model of mania related to bipolar disorder (BD). Here we tested the hypothesis that GBR12909 injection impairs habituation and induces hyperlocomotion in mice, along with changes in cytokines and neurotrophic factors levels, as observed in BD patients. We also tested if lithium carbonate, sodium valproate and aripiprazole prevent GBR12909-induced locomotion.

Pro-inflammatory cytokines and soluble receptors in response to acute psychosocial stress: differential reactivity in bipolar disorder.

Mounting evidence suggests a chronic pro-inflammatory state in individuals with bipolar disorder (BD). Stress exposure is known to exacerbate several inflammatory conditions as well as psychiatric disorders. Here, we analyzed plasma levels of pro-inflammatory cytokines and their soluble receptors to realistic acute psychosocial stress challenge in BD.
