Blocking IL-11 Softens Ovaries, Boosts Fertility, Delays Menopause

Summary

Story summary

Huazhong University researchers showed that blocking interleukin-11 reduces ovarian matrix stiffness and boosts mouse fertility.
They reported that ovarian stiffness rises with age in humans, mice and rats, and older or disease-affected human ovaries have higher IL-11 levels.
RNA-loaded nanoparticles silencing IL-11 lowered collagen buildup and rigidity in aged mouse ovaries, producing more pups per pregnancy and prompting the authors to propose repurposing anti-IL-11 drugs to delay menopause.
