Nicotine Inhibits FcεRI-induced Cysteinyl Leukotrienes and Cytokine Production without Affecting Mast Cell Degranulation Through Alpha7/Alpha9/Alpha10-nicotinic Receptors Smokers are less likely to develop some inflammatory and allergic diseases. In Brown-Norway rats, nicotine inhibits several parameters of allergic asthma including the production of Th2 cytokines and the cysteinyl leukotriene LTC4. Cysteinyl ...

Pharmacological enhancement of glymphatic function in humans increases the clearance of Alzheimer’s disease-related proteins Alzheimer’s disease (AD) is characterized by the mis-aggregation of amyloid β (Aβ) and tau, which is proposed to be driven by impaired Aβ and tau clearance.

🧠 Key insight (this is the important part)

What your gene set suggests is not a primary RBC disorder, but rather a “triple-hit model” affecting oxygen delivery:

1. Microvascular flow problem
SERPINC1
PTGIS

→ capillary obstruction / dysregulation

2. Oxidative stiffening of RBCs
PRDX6

→ reduced deformability

3. Systemic metabolic stress
DARS2, FBXL4

→ worsens RBC energy + redox environment

🔬 Why this matters for ME/CFS specifically

This combination maps almost perfectly onto:

Reduced capillary perfusion
Impaired oxygen extraction
“Pseudo-hypoxia” despite normal oxygen saturation

👉 Which is exactly what many ME/CFS physiological studies show.
