Polluted lungs
A new study published in Nature Medicine suggests that lifelong exposure to tiny airborne particles leads to their accumulation in lymph nodes in the lungs and to impaired immune function [1]. Age-related lung diseases and pollution With age, people become more susceptible to many diseases, with the lungs being one of the most affected organs....
Fat and skinny
In a new paper, Yale scientists present encouraging data from an unprecedented human study of caloric restriction, a powerful anti-aging intervention [1]. Eat less, live more Despite all the might of today’s science, simple lifestyle choices are still the clearest option for living longer and healthier. These choices include being physically active, eating better, and...
Mouse Brain Internal
Researchers, publishing in the journal Aging, have discovered that a protein called hedgehog alleviates the tissue-specific, age-related inflammation of the microglia, the maintenance cells of the brain. The aging differences between tissue types To begin this research, the team first performed a gene expression analysis on four different types of murine macrophages: bone marrow-derived macrophages...
Back pain
A paper published in Aging has shown that it is possible to treat spinal disc degeneration through altering the epigenetics of macrophages. Macrophages and inflammaging Macrophages are the clean-up crew of the immune system, engulfing and destroying harmful germs, but their polarization is a double-edged sword. On one hand, M1 macrophages serve on the front...
Macrophage
A paper published in Nature Communications reveals that, rather than just summoning fibroblasts, inflammatory macrophages themselves form fibrous tissue that is the basis of scars. The dual role of macrophages Macrophages perform two critical roles in the immune system. After an injury, M1 macrophages spur local inflammation, causing immune cells to converge on the area...
Human heart
A study on animals with autoimmune myocarditis was recently released in the journal Cell Reports [1], showing the impact of heart inflammation on the types of immune cell that are formed in the heart. This could have a significant impact on our understanding of cardiac aging. What is myocarditis and how is it relevant to...
