Dysregulation of the complement and coagulation cascade in treated schizophrenia and bipolar disorder patients

ABSTRACT: A better understanding of the proteomic profile after bipolar disorder (BD) and schizophrenia (SCZ) treatment, through monitoring its progression, may assist the development of novel therapeutic strategies with the ability to reduce or control possible side effects. In this study, proteomics analysis employing liquid chromatography coupled to mass spectrometry (LC-MS) and bioinformatic tools were applied to identify differentially expressed proteins in serum of treated BD and SCZ patients. In total, 10 BD patients, 10 SCZ patients, and 14 healthy participants were included. From 25 serum proteins significantly altered (> 1.5- fold change), 8 were down-regulated in the BD group, while 7 proteins were up- regulated and 2 down-regulated in SCZ group when compared against healthy controls. Bioinformatics analysis based on these 25 proteins validated two main altered pathways previously described in the literature; furthermore, it revealed that opposite expressions of the complement and coagulation cascades were the most significant biological processes involved in these pathologies. Associations of disease-proteins and pathways suggest therapeutic intervention or prevention of comorbidities risks for BD and SCZ. Further validation and investigation are required to define whether there is correlation between complement and coagulation cascade expression for both diseases and cardiovascular diseases.

A better understanding of the proteome profile after bipolar disorder (BD) and schizophrenia (SCZ) treatment, besides monitoring disease progression, may assist on the development of novel therapeutic strategies with the ability to reduce or control possible side effects. In this pilot study, proteomics analysis employing nano liquid chromatography coupled to mass spectrometry (nLC-MS) and bioinformatic tools were applied to identify differentially abundant proteins in serum of treated BD and SC ...[more]

Project description:Narcolepsy type 1 (NT1) is a rare, chronic and disabling neurological disease causing excessive daytime sleepiness and cataplexy. NT1 is characterized pathologically by an almost complete loss of neurons producing the orexin neuropeptides in the lateral hypothalamus. Genetic and environmental factors strongly suggest the involvement of the immune system in the loss of orexin neurons. The cerebrospinal fluid (CSF), secreted locally and surrounding the central nervous system (CNS), represents an accessible window into CNS pathological processes. To gain insight into the biological and molecular changes in NT1 patients, we performed a comparative proteomics analysis of the CSF from 21 recent-onset NT1 patients and from two control groups: group 1 with somatoform disorders, and group 2 patients with hypersomnia other than NT1, to control for any potential effect of sleep disturbances on CSF composition. To achieve an optimal proteomic coverage analysis, the twelve most abundant CSF proteins were depleted, and samples were analyzed by nano-flow liquid chromatography tandem mass spectrometry (nano-LC-MS/MS) using the latest generation of hybrid Orbitrap mass spectrometer. Our study allowed the identification and quantification of up to 1943 proteins, providing a remarkably deep analysis of the CSF proteome. Interestingly, gene set enrichment analysis indicated that the complement and coagulation systems were enriched and significantly activated in NT1 patients in both cohorts analyzed. Notably, the lectin and alternative complement pathway as well as the downstream lytic membrane attack complex were congruently increased in NT1. Our data suggest that the complement dysregulation in NT1 patients can contribute to immunopathology either by directly promoting tissue damage or as part of local inflammatory responses. We therefore reveal an altered composition of the CSF proteome in NT1 patients, which points to an ongoing inflammatory process contributed, at least in part, by the complement system.
