Официальное название

Regulatory Mechanisms of EGR2 and NLRP3 Inflammatory Pathways in Cognitive Impairment and Depressive-Anxiety-Like Behaviors Associated With Obstructive Sleep Apnea-Hypopnea Syndrome

Обзор

Obstructive sleep apnea-hypopnea syndrome (OSAS) is a common disorder in which repeated airway blockages during sleep lead to low oxygen levels, inflammation, and disrupted sleep. Many OSAS patients-both children and adults-experience problems with memory, attention, and mood, such as anxiety or depression. However, the exact molecular drivers of these brain changes are not fully understood. This observational study will enroll: Children (ages 2-18) and adults (\>18 years) with OSAS, as well as age- and sex-matched healthy volunteers. Clinical assessments: Children will undergo routine ENT examinations (including nasal endoscopy and X-rays); adults will have an overnight sleep study (polysomnography). All participants will complete questionnaires on sleepiness (e.g., ESS), mood (PHQ-9, GAD-7), and cognitive screening (MoCA for adults, age-appropriate scales for children). Sample collection: A small blood draw (3 mL) and, when applicable (e.g., adults undergoing surgery), a tiny subcutaneous fat biopsy. Saliva samples will also be collected. Laboratory tests: Measure expression levels of two key inflammatory pathway genes-EGR2 and NLRP3-in blood cells, saliva, and fat tissue using RNA sequencing, RT-qPCR, and Western Blot. Correlate these molecular markers with sleep parameters (AHI, oximetry), cognitive scores, and mood scores. Data analysis: Develop and validate machine-learning models that integrate data from multiple tissues to predict who is at highest risk for cognitive or mood disturbances.

Вмешательства

  • Процедура EGR2/NLRP3 pathway activity
    Peripheral blood collection \& PBMC isolation: Children: 3 mL venous blood drawn from the right antecubital vein preoperatively; Adults: 3 mL fasting venous blood drawn the morning after PSG. Collected in EDTA tubes; PBMCs separated via Ficoll-Paque density gradient. Flow cytometry: 1×10⁶ PBMCs stained for CD14/CD16, HLA-DR, CD11b, CD80/CD86, CD163/CD206. RNA extraction: Remaining PBMCs lysed in TRIzol and stored at -80 °C for RT-qPCR of EGR2, NLRP3, and downstream genes Serum/plasma: Within
  • Процедура fatty tissue
    Subcutaneous fat biopsy (adults undergoing surgery): 100-200 mg obtained intraoperatively, placed in RNAlater at 4 °C for 24 h, then frozen at -80 °C for downstream RNA-seq, RT-qPCR, and Western blot analyses of EGR2, NLRP3, and related inflammatory markers
