Abstract 415: Cardioprotective Effects of Interleukin-15 in Immortalized Human Ventricular Cardiomyocytes
Bibliographic record
Abstract
Interleukin-15 (IL-15) is a pleotropic cytokine that has a profound effect on the proliferation, survival and differentiation of many distinct cell types. The IL-15 receptor complex has 3 subunits: the unique receptor chain IL-15 receptor alpha (IL-15Rα), and two receptor chains shared with interleukin-2 (IL-2) and/or other cytokines, referred to as IL-2 receptor beta (IL-2Rβ) and IL-2 receptor gamma/gamma common chain (IL-2Rγ/γc), respectively. To our knowledge, this is the first study to examine the effects of IL-15 in immortalized human cardiomyocytes. Data collected by RT-PCR shows mRNA expression of IL-15Rα, IL-2Rβ and IL-2 Rγ/γc in these cells. Additionally, western blotting for IL-15Rα, IL-2Rβ and IL-2 Rγ/γc confirms the presence of all three IL-15 receptors. Early experiments examining the effect of IL-15 on cardiomyocyte cell survival show a statistically significant protective effect of IL-15 on the survival of cells exposed to tunicamycin, a pharamacological endoplasmic reticulum (ER) stress inducing agent. These findings suggest that IL-15 signaling may be an important cardioprotective pathway that is involved in the cardiac ER stress response. As ER stress is a major component of multiple different cardiac pathologies, such as myocardial infarction, heart failure and diabetes, uncovering the molecular mechanism by which IL-15 protects the heart will allow for deeper understanding of the cardiac ER stress response.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
