Calming innate immune 'memory' to protect transplanted organs

Targeting trained immunity in transplantation

NIH-funded research Icahn School of Medicine at Mount Sinai · NIH-11322152

This project looks at ways to turn down the innate immune system's 'memory' to help organ transplant patients avoid rejection and reduce side effects from current immune-suppressing drugs.

What this research studies

After an organ transplant, some innate immune cells develop a long-lasting heightened response called trained immunity that can drive rejection. The team will study how epigenetic changes in bone marrow stem cells produce these trained innate immune cells and will test strategies to block or reverse that programming. Research combines laboratory models, analysis of patient samples, and early clinical data to link trained immunity with graft outcomes. The goal is to develop treatments that can be added to current care to improve long-term transplant survival and reduce complications.

Who could benefit from this research

Good fit: Ideal candidates would be people who have received or are scheduled to receive an organ transplant and who are willing to provide samples or take part in related clinical protocols.

Not a fit: People without organ transplants or whose problems are due to non-immune surgical or anatomical issues would not expect to benefit directly.

Why it matters

Potential benefit: If successful, this work could lower rejection rates and allow gentler immunosuppression, reducing infections and other drug-related harms.

How similar studies have performed: Animal studies and some preliminary clinical sample analyses suggest trained immunity affects graft outcomes, but moving from those findings to proven treatments is still a new and unproven area.
