Reading Time: 6 minutesThe bacterial taxa Akkermansia muciniphila has been identified as a critical keystone microbial species. Its proliferation has repeatedly been tied to improved metabolic outcomes, enhanced gut barrier integrity, and balanced inflammatory tone. As a Gram-negative, anaerobic bacterium from the Verrucomicrobia phyla, its unique property lies in its digestion of mucin in the…

Reading Time: 5 minutesMy last post described the role of immunosenescence in the process of aging, and touched on immunotherapy as a potential strategy to restore immune function. Immunotherapy is being applied in various contexts, including cancer, to reprogram the immune system and build resiliency. Unfortunately, only a fraction of patients demonstrate durable, robust response…

Reading Time: 8 minutesCellular senescence is a hallmark of aging, with senescent cells exhibiting a range of dysfunctions, including metabolic reprogramming, DNA damage, oxidative stress, and secretion of the senescence-associated secretory phenotype (SASP). Although senescence accrues with age, it can occur at any point during the life cycle and contributes to chronic disease risk. Immunosenescence…

Reading Time: 7 minutesArguably one of the most indispensable trace elements, iron is a requirement for DNA synthesis, oxygen delivery and energy metabolism, as well as immune function. Nonetheless, iron must be delicately handled and tightly regulated to mitigate toxic consequences. The Goldilocks paradox lies in its reactive nature. As a transition metal, the iron…
