Scientists are reframing the thymus—a two-lobed gland behind the breastbone—as a central regulator of aging and immune health, with healthier thymuses linked to longer lifespans, lower cancer and heart-disease risk, and better responses to cancer immunotherapy; researchers are pursuing thymus rejuvenation and engineered thymic tissue to boost vaccines and transplant tolerance.
AI analysis of CT scans shows adults with healthier thymus tissue have around 50% lower risk of death, 63% lower risk of heart disease, and 36% lower risk of lung cancer, challenging the idea that the thymus shrinks and becomes irrelevant after puberty; a second study also linked thymic health to better responses to cancer immunotherapy, suggesting thymus health could help gauge aging risk and guide treatment.
New AI-driven analysis of CT scans shows that adults with a healthier thymus are linked to longer life, lower risk of cardiovascular disease, and reduced lung cancer risk; a separate cancer-immunotherapy study found better thymic health predicted better treatment response and longer survival. Lifestyle factors like smoking and higher body weight correlate with poorer thymic health. While promising, the approach isn’t ready for routine clinical use and more research is needed to translate findings into prevention or treatment strategies.
New Nature studies from Aarhus University suggest the thymus—a small immune organ once thought to fade after youth—continues to influence disease risk and how well patients respond to cancer immunotherapy. Better thymus function linked to improved treatment outcomes and longer survival; its decline is accelerated by smoking, obesity, and low activity, pointing to prevention angles and potential for tailoring cancer therapies by patients’ immunological status.
MIT researchers demonstrated in aging mice that delivering mRNA encoding key immune-signaling pathways causes the liver to transiently manufacture factors that boost thymus-driven T-cell production. This rejuvenation improved immune responses to vaccines and cancer immunotherapy with minimal side effects, and slowed tumor progression in treated mice. The therapy has not been tested in humans and would require ongoing injections to maintain benefits, but it represents a potential approach to counteract age-related immune decline and possibly broader aging processes.
Broad Institute researchers show in old mice that injecting mRNA into the liver triggers thymic signals (DLL1, FLT3-L, IL-7), reviving T-cell production. Over four weeks, older mice had more diverse T cells, stronger vaccine responses, and better anti-cancer activity, though the boost was temporary and human trials are needed, with the findings published in Nature.
The study presents a novel approach to counteract immune decline in aging by using mRNA delivered to the liver to produce key immune factors (DLL1, FLT3-L, IL-7), which rejuvenates T cell production, enhances vaccine responses, and improves tumor immunotherapy efficacy in aged mice, without adverse effects or autoimmunity.
A study suggests that the thymus gland, often considered 'useless' in adulthood, may play a crucial role in fighting cancer and maintaining health. Researchers found that individuals who had their thymus removed faced a higher risk of death and cancer, with the cancer being more aggressive. The study, published in The New England Journal of Medicine, indicates that the thymus contributes to T-cell production in adults, which is vital for a healthy immune system. The findings suggest that preserving the thymus should be prioritized in medical procedures.
Researchers have discovered the presence of Microfold cells, or M cells, in the thymus, a vital organ for immune system development. M cells are typically found in the intestines and play a key role in the body's immune response. The thymic M cells resemble their intestinal counterparts and provide valuable insights into the complex interactions and functions of the thymus. This unexpected discovery sheds light on the organ's role in shaping the immune response and may have implications for understanding immune system development in other parts of the body.
The thymus, an organ previously believed to be non-functional in adults, may actually play a crucial role in our health and cancer prevention as we age, according to recent research. A study found that adults who had undergone thymectomy (removal of the thymus) had a significantly higher risk of dying and developing cancer compared to those who hadn't. The thymus is involved in developing the immune system and producing immune T cells. The findings suggest that the thymus remains functionally important in adulthood and that the consequences of thymectomy should be carefully considered.
New research led by Harvard has revealed the crucial role of the thymus organ in maintaining immune health and preventing cancer in adults. The study found that individuals who had their thymus removed had a significantly higher risk of death from various causes, including a twofold increase in cancer risk. The thymus, previously considered expendable in adults, is now recognized as essential for immune health as we age, particularly in warding off cancer. The study highlights the importance of the thymus in protecting against the development of cancer and maintaining overall health.
A study led by Massachusetts General Hospital reveals that the thymus, previously thought to be nonfunctional in adults, plays a critical role in adult health by preventing cancer and possibly autoimmune disease. The research found that adults who had their thymus removed during surgery had a significantly higher risk of death and developing cancer compared to those who did not undergo thymectomy. The study also showed that thymectomy patients had lower production of new T cells and higher levels of pro-inflammatory molecules in their blood. The findings suggest that the consequences of thymus removal should be carefully considered in medical procedures.
