The research investigated the "priming" effect of chronic stress on the innate immune system. Traditionally, chronic stress is viewed as purely immunosuppressive (weakening the immune system), but this review-worthy study highlights a more complex mechanism where stress prepares the immune system for a hyper-responsive state.
: In both mice and humans, chronic stress was found to reprogram myeloid progenitor cells in the bone marrow. This leads to an increased production of monocytes that are more reactive to future threats. 109595
: While this "primed" state might seem helpful for fighting infections, it often leads to pathological inflammation , increasing the risk for cardiovascular diseases, autoimmune disorders, and severe inflammatory responses (such as those seen in COVID-19). Critical Review and Assessment The research investigated the "priming" effect of chronic
The identifier primarily refers to a significant scientific study published in Cell Reports titled "Chronic stress primes innate immune responses in mice and humans," which explores how long-term psychological stress impacts the immune system at a cellular level. Overview of Study 109595 This leads to an increased production of monocytes
: It also refers to a recent eLife reviewed preprint (109595) that uses fruit flies to model RVCL-S , a rare genetic disease affecting blood vessels in the brain and retina.
: A review from MIT researchers (indexed under 109595 ) examines manganese-based oxides as catalysts for energy conversion in fuel cells.
: Experts note that while the "priming" is clearly observed, the exact duration of these epigenetic changes remains an open question for future research.
