Type:
High-density lipoprotein (HDL) cholesterol is often referred to as "good" cholesterol because it helps transport cholesterol away from the arteries and back to the liver, where it can be processed and removed from the body.
Some research suggests that higher levels of HDL cholesterol may be associated with a lower risk of certain types of cancer. This could be due to HDL's role in reducing inflammation and oxidative stress, both of which are linked to cancer development.
Other studies have indicated that very high levels of HDL cholesterol might be associated with an increased risk of certain cancers.
While higher levels of HDL cholesterol are generally associated with cardiovascular health and may have protective effects against certain cancers, the evidence is mixed, and the implications for cancer risk and prognosis vary by cancer type.

Asthma

Definition: Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction, airway hyperresponsiveness, mucus hypersecretion, and recurrent episodes of wheezing, cough, chest tightness, and shortness of breath. Airflow limitation is often reversible, but chronic inflammation can produce airway remodeling and more persistent obstruction.

Main Pathways Involved in Asthma — Ranked by Importance

Rank Pathway / Target Typical Direction in Asthma Importance Role
1 IL-4 / IL-13 → JAK / STAT6 ↑ Very High Central Type-2 asthma pathway. Promotes Th2 responses, IgE production, mucus hypersecretion, airway hyperresponsiveness, and remodeling.
2 IL-5 → Eosinophils ↑ Very High Drives eosinophil maturation, survival, recruitment, and activation. A major pathway in eosinophilic asthma and a clinically validated therapeutic target.
3 IL-33 → ST2 / IL1RL1 → ILC2 ↑ Very High Major upstream epithelial alarmin pathway. Activates ILC2 and promotes IL-5 and IL-13 production, eosinophilia, mucus secretion, and airway hyperresponsiveness.
4 TSLP ↑ Very High Epithelial alarmin that activates dendritic cells, Th2 immunity, mast cells, and ILC2. Particularly important in allergic and severe Type-2 asthma.
5 IgE → FcεRI → Mast-cell activation ↑ Very High Fundamental allergic-asthma pathway. Allergen-mediated IgE cross-linking activates mast cells and causes release of histamine, leukotrienes, prostaglandins, and cytokines.
6 5-LOX / ALOX5 → LTC4 / LTD4 / LTE4 → CysLT1 ↑ Very High Cysteinyl leukotrienes are potent bronchoconstrictors and promote mucus secretion, vascular permeability, and eosinophilic inflammation.
7 Airway smooth muscle / β2-adrenergic receptor → cAMP / PKA Contraction ↑; therapeutic β2 signaling ↑ Very High Airway smooth-muscle contraction directly causes reversible airflow obstruction. β2-receptor activation increases cAMP and PKA, producing bronchodilation.
8 NF-κB ↑ High Major inflammatory transcription pathway controlling cytokines, chemokines, adhesion molecules, inflammatory enzymes, and immune-cell activation.
9 TGF-β1 → SMAD2 / SMAD3 ↑ High Major driver of chronic airway remodeling, extracellular-matrix deposition, subepithelial fibrosis, and airway smooth-muscle growth.
10 ROS / Oxidative Stress ↔ Nrf2 ROS ↑; Nrf2 often insufficient High Oxidative stress damages airway epithelium and amplifies NF-κB, MAPK, cytokine signaling, mucus production, and airway hyperresponsiveness. Nrf2 provides a protective antioxidant response.
11 IL-17 / Th17 → CXCL8 / IL-8 → Neutrophils ↑ High in Severe / Non-Type-2 Asthma Important in neutrophilic, severe, and corticosteroid-resistant asthma. Promotes neutrophil recruitment and persistent airway inflammation.
12 NLRP3 Inflammasome → IL-1β / IL-18 ↑ Moderate-High Promotes innate inflammatory signaling and neutrophilic airway inflammation, particularly in severe and non-Type-2 asthma.
13 PI3K / AKT ↑ Moderate Supports inflammatory-cell survival, airway smooth-muscle proliferation, mucus production, and corticosteroid resistance.
14 MAPK / ERK / p38 / JNK ↑ Moderate Regulates cytokine production, epithelial responses, smooth-muscle activity, inflammatory-cell activation, and airway remodeling.
15 Epithelial Barrier Integrity ↓ Moderate Impaired epithelial integrity allows greater allergen penetration and promotes release of IL-33, TSLP, and IL-25.
16 E-cadherin / ZO-1 ↓ Moderate Reduced adherens-junction and tight-junction proteins contribute to impaired airway-barrier function and increased inflammatory signaling.
17 MUC5AC / Goblet-cell Hyperplasia ↑ Moderate Drives mucus hypersecretion and mucus plugging, particularly under IL-13 signaling.
18 CCL11 / Eotaxin-1 → CCR3 ↑ Moderate Recruits eosinophils into airway tissue and contributes to Type-2 airway inflammation.
19 TNF-α ↑ Moderate Promotes inflammatory-cell recruitment, endothelial activation, airway hyperresponsiveness, and remodeling.
20 NADPH Oxidase / NOX ↑ Moderate Generates reactive oxygen species and contributes to oxidative injury and inflammatory signaling.
21 VEGF ↑ Secondary / Remodeling Promotes increased airway vascularity, vascular permeability, and airway-wall remodeling.
22 MMP-9 ↑ Secondary / Remodeling Extracellular-matrix remodeling enzyme associated with inflammation, epithelial injury, and structural airway changes.
23 Collagen Deposition ↑ Secondary / Remodeling Contributes to subepithelial fibrosis, airway-wall thickening, and progressively less reversible airflow obstruction.

Core Asthma Pathway Summary

Primary Type-2 pathway:
Allergen / epithelial injury → IL-33 + TSLP + IL-25 ↑ → ILC2 + dendritic cells + Th2 ↑ → IL-4 + IL-5 + IL-13 ↑ → IgE ↑ + eosinophils ↑ + mast-cell activation ↑ → bronchoconstriction + mucus ↑ + airway hyperresponsiveness.

Allergic effector pathway:
Allergen → IgE / FcεRI → mast-cell degranulation → histamine + prostaglandins + cysteinyl leukotrienes → acute bronchoconstriction and airway inflammation.

Oxidative / inflammatory pathway:
Allergens / pollutants / inflammatory cells → ROS ↑ → NF-κB + MAPK + PI3K / AKT ↑ → inflammatory cytokines and chemokines ↑ → epithelial damage and airway inflammation.

Severe / neutrophilic asthma pathway:
NLRP3 ↑ + IL-1β ↑ + Th17 / IL-17 ↑ → CXCL8 ↑ → neutrophils ↑ → persistent inflammation and corticosteroid resistance.

Airway-remodeling pathway:
Chronic inflammation → TGF-β1 / SMAD2 / SMAD3 ↑ → collagen deposition ↑ + VEGF ↑ + MMP-9 dysregulation → subepithelial fibrosis + airway-wall thickening + smooth-muscle hypertrophy → persistent airflow limitation.
