Can Rejuvenating Aging Blood Systems Decelerate the Aging Process?

Recent research suggests that infusing young blood into older bodies has a rejuvenating effect. This leads to stronger heartbeats, increased muscle strength, and sharper cognitive function in aging individuals.

Scientists are exploring ways to capture or replicate the elements of young blood for potential use in pill form. However, new findings from Emmanuelle Passegué, Ph.D., director of the Columbia Stem Cell Initiative, suggest that rejuvenating the system responsible for producing blood may be the most effective approach.

Passegué and her graduate student, Carl Mitchell, discovered that an anti-inflammatory drug, already approved for use in rheumatoid arthritis, can reverse some age-related effects on the hematopoietic system in mice. This breakthrough holds promise for maintaining healthier blood production in the elderly.

Rejuvenating the home of blood stem cells. The researchers found that an inflammatory signal released from old bone marrow, IL-1B, was critical in driving aging in blood stem cells. And the drug, anakinra, returned the blood stem cells to a younger, healthier state. Images of young (top) and old bone marrow courtesy of Emmanuelle Passegué.

The study focused on blood stem cells, which create all blood cells, and their surrounding niches within the bones. Over time, these stem cells undergo changes, leading to issues like anemia, decreased immune cell production, and genome integrity problems, which can contribute to blood cancers. Previous attempts to rejuvenate these stem cells through exercise, calorie restriction, or transplantation were unsuccessful.

Upon closer examination of the bone marrow environment where the stem cells reside, the researchers found that inflammation within the aging niche was a key factor driving the aging process. An inflammatory signal called IL-1B released from damaged bone marrow was identified as a critical driver of aging in blood stem cells. Administering the drug anakinra, which blocks IL-1B, effectively returned the blood stem cells to a more youthful and healthier state.

The researchers are now investigating whether similar processes occur in humans and whether rejuvenating the stem cell niche earlier in life, such as in middle age, would be a more effective strategy. Passegué believes that treating elderly patients with anti-inflammatory drugs targeting IL-1B function could help maintain healthier blood production, and she hopes this discovery will lead to clinical testing.

As life expectancy continues to increase, understanding the mechanisms of aging and developing strategies for healthy longevity becomes increasingly important. Linda Fried, MD, MPH, dean of the Mailman School of Public Health at Columbia University, emphasizes the need for research in this area to promote well-being throughout extended lifespans.

“Now it is imperative to conduct the science to determine how to create health and well-being across the full length of those lives,” says Linda Fried, MD, MPH, dean of the Mailman School of Public Health at Columbia University and director of the Butler Columbia Aging Center. “This must include research to understand the mechanisms of normal aging and how to fully develop the huge opportunities to create healthy longevity for all.”
