In conclusion, the effects of MR on the gut barrier were likely related to alleviation of the oscillations of inflammation-related microbes. MR can enable nutritional intervention against age-related gut barrier dysfunction.
Clearing Senescent Cells from the Neural Stem Cell Niche Rapidly Improves Neurogenesis in Old Mice

Neurogenesis is the generation of new neurons in the brain, and their integration into existing neural circuits. It is essential to learning and recovery from injury. Neurogenesis is most studied in the hippocampus, connected to memory, and in mice. In humans the debate continues over the degree to which neurogenesis takes place in adult life, and where in the brain it does take place, but the pendulum leans towards this being a significant process over much of the life span. Importantly, neurogenesis appears to decline with age, while increasing neurogenesis produces benefits to cognitive function.
This context is why today's open research materials make for an interesting expansion of the known benefits of senolytic drugs. Senolytic therapies are those capable of selectively destroying senescent cells. Cells become senescent throughout life, usually upon reaching the Hayflick limit to cell replication, but also as a result of damage and stress. Senescent cells enter a state in which they ...
