Cystic Fibrosis Plasma

About Cystic Fibrosis Plasma

Cystic Fibrosis Plasma for CFTR and Chronic Airway Inflammation Research

Cystic Fibrosis Plasma is collected from IRB-consented donors clinically diagnosed with cystic fibrosis (CF) and processed within one day of collection to preserve labile analytes such as cytokines, proteins, and metabolites. Cryopreserved and available in custom aliquots, this human plasma supports research into CFTR-driven disease biology, chronic neutrophilic inflammation, nutritional status, and modulator therapy response. Research Use Only (RUO).

Molecular Basis and Why Plasma

• Cystic fibrosis is an autosomal recessive monogenic disease caused by variants in CFTR, which encodes a cAMP-regulated chloride and bicarbonate channel at the apical surface of epithelial cells.
• Loss of CFTR function dehydrates airway surface liquid and impairs mucociliary clearance, producing viscous secretions, mucus plugging, chronic bacterial airway infection, and progressive bronchiectasis.
• F508del is the most common disease-causing variant, and variant class determines eligibility for CFTR modulator therapy, so genotype is central to study design.
• CF is a multi-organ disease: exocrine pancreatic insufficiency, malabsorption of fat-soluble vitamins, CF-related diabetes, CF liver disease, and impaired growth are all common.
• The airway inflammatory response in CF is predominantly neutrophilic and is accompanied by measurable systemic inflammatory mediators, making plasma useful for circulating cytokine, acute-phase, and proteomic readouts.
• Plasma is acellular and therefore appropriate for soluble biomarker, metabolomic, and nutritional analyte work rather than cell-based assays.

Donor Stratification Available

• CFTR genotype where documented, including F508del homozygous and heterozygous donors
• CFTR modulator therapy status: on elexacaftor/tezacaftor/ivacaftor, on other modulator, or modulator-naive
• Pancreatic sufficiency versus insufficiency
• Lung function category and documented exacerbation history
• Chronic airway colonization status where documented, such as Pseudomonas aeruginosa
• Comorbidities including CF-related diabetes and CF liver disease; pediatric and adult age bands
• Matched healthy controls available
