Inhibiting IL11: a novel approach to turning back the clock.

Abstract

The World Health Organization recognizes frailty and multimorbidity as major global health issues and underscores the need for effective interventions. Recent advances have identified interleukin-11 (IL-11), a pro-inflammatory cytokine, as a key player in modulating aging pathways (such as ERK, AMPK, mTOR and JAK-STAT3). Studies have shown that IL-11 inhibition can lead to improved health span and lifespan in animal models, with potential applications in humans. By targeting IL-11, researchers aim to mitigate age-related diseases, such as cancer, fibrosis, and multimorbidity, which pose significant healthcare challenges worldwide. IL-11 inhibition offers a promising strategy, with preclinical trials demonstrating its ability to regenerate renal cells, reduce hepatocyte death, and mitigate liver fibrosis. Further research is necessary to fully elucidate the mechanisms of IL-11 inhibition and its therapeutic potential. If successful, this approach could lead to the development of novel pharmacological interventions, promoting healthier aging and increasing human lifespan.
