Caveolae and Caveolins in the Respiratory System
Bibliographic record
Abstract
Caveolae are flask-shaped invaginations of the plasma membrane that are present in most structural cells. They owe their characteristic Omega-shape to complexes of unique proteins, the caveolins, which indirectly tether cholesterol and sphingolipid-enriched membrane microdomains to the cytoskeleton. Caveolins possess a unique scaffolding domain that anchors receptors, ion channels, second messenger producing enzymes, and effector kinases, thereby sequestering them to caveolae, and modulating cellular signaling and vesicular transport. The lungs express numerous caveolae and high levels of caveolins; therefore they likely play an important role in lung physiology. Indeed, recent and ongoing studies indicate important roles for caveolae and caveolins in the airway epithelium, airway smooth muscle, airway fibroblasts, airway inflammatory cells and the pulmonary vasculature. We review the role of caveolae and caveolins in lung cells and discuss their involvement in cellular signaling associated with asthma, COPD, lung cancer, idiopathic pulmonary fibrosis and pulmonary vascular defects.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
