Cerebrospinal Fluid Biomarkers in Opioid Dependence: Evidence of Neuroimmune Activation and Ion Composition Changes, Without Alteration in Orexin-A
Journal: Addiction biology,
Year: 2025
- Background

- Results
Opioid abuse is a serious global health challenge, leading to increased morbidity, mortality, and societal costs. This study aims to explore neuroinflammation, neuronal damage, and potential changes in the orexin system or β-amyloid metabolism in the cerebrospinal fluid (CSF) of individuals undergoing opioid replacement therapy (OST). This cross-sectional study compared cerebrospinal fluid biomarkers in individuals undergoing OST with controls.
Cerebrospinal fluid samples were collected using a 25-G non-injured needle by lumbar puncture performed in an upright sitting position. Collection takes place during the day and ranges from 9 a.m. to 1 p.m. The collected CSF samples were centrifuged at a rotational rate of 2000g for 10 minutes at room temperature to remove cells and debris, and then aliquoted in a container at -80°C for subsequent biochemical analysis. Tyrosine protein kinase receptor 3 (TYRO3), tyrosine kinase receptor Axl (AXL), tyrosine kinase Mer (MER), and growth arrest-specific protein 6 (GAS6) were analyzed using Olink Proteomics' Olink Explore 3072 platform.
Each participant provided a thorough medical history, including medication use within the past 6 months, followed by a lumbar puncture to obtain a CSF sample. These samples contain molecules associated with neuroinflammation, neuronal and glial damage, and β-amyloid. Metabolic and orifice peptide function in the participants' cerebrospinal fluid was analyzed, while electrolyte levels were also detected. Specifically, we analyzed sTREM-2, YKL-40, IL-1β, IL-6, IL-8, IL-10, TNF-α, AXL, MER, TYRO3, GAS6, NfL, GFAP, total tau (T-tau), phosphorylated tau (P-tau), neurogranulin protein, Aβ40, Aβ42, Aβ42/Aβ40 ratio, orifice peptide A, sPDGFR-β, and electrolytes. The study included 15 control subjects and 17 subjects in the opioid replacement treatment group. Patients receiving opioid replacement therapy have elevated levels of sTREM-2, Aβ42/Aβ40, and NfL in the cerebrospinal fluid. Conversely, the concentrations of sodium and chloride ions were lower compared to the control group. No significant differences were found between groups in other biomarkers, including Aureixin-A. However, when standardized to Aβ40 levels, YKL-40, IL-8, TYRO3, and P-τ were also elevated in individuals with opioid dependence. Elevated markers of neuroimmune activation, neuronal damage, and β-amyloid metabolism in opioid dependence suggest that CNS inflammation is a factor in its pathological mechanism. A decrease in electrolyte levels means a disturbance in the regulation of water in the cerebrospinal fluid, which may be associated with impaired glial function. These findings highlight neural and non-neural mechanisms in opioid dependence.

FAQs
What types of biological fluids are compatible with Olink's biomarker panels for research applications?
Olink's assays support a wide range of body fluids, including plasma, serum, cerebrospinal fluid (CSF), saliva, and cell culture supernatants. Each fluid type undergoes rigorous validation to ensure data reproducibility, with detailed protocols provided for sample collection, storage, and preprocessing to minimize pre-analytical variability.
How does Olink ensure high specificity and sensitivity in protein detection for low-abundance biomarkers?
The platform utilizes Proximity Extension Assay (PEA) technology, which combines dual antibody recognition with DNA-based amplification, enabling ultrasensitive detection (sub-pg/mL range) even in complex matrices. This minimizes cross-reactivity and enhances specificity for quantifying low-abundance proteins in research samples.
Can researchers customize biomarker panels for specific experimental pathways or disease mechanisms?
Yes, Olink offers tailored panel configurations—from focused 20-plex panels to broad 500+ protein profiles—allowing researchers to select targets relevant to their study (e.g., inflammation, oncology, or neurology pathways). Custom panels can include proprietary targets or synthetic controls upon request.
What bioinformatics support is available for proteomic data analysis and integration with other omics datasets?
Olink provides dedicated software tools for quality control, differential expression analysis, and pathway enrichment. Data outputs are compatible with major transcriptomic/metabolomic platforms, enabling multi-omics correlation studies through co-expression networks and multivariate visualization.
