In conclusion, plasma levels of IGHA2, APOA and HPT are associated with subclinical atherosclerosis independently of traditional risk factors and offers potential to predict this disease. The panel could improve primary prevention strategies in areas where imaging is not available.
A Lesser Diversity of Circulating Antibodies in the Aging Killifish Immune System
https://www.fightaging.org/archives/2022/04/a-lesser-diversity-of-circulating-antibodies-in-the-aging-killifish-immune-system/
Short-lived killifish are one of the more recently adopted animal models of aging. All such models are a trade-off between the cost of running studies and the relevance of their biochemistry to long-lived mammals such as our own species. Fortunately, a lot of the cellular biochemistry of aging is similar enough to make such models useful; unfortunately the differences are often significant enough to sink specific attempts to discover mechanisms and build new therapies. Here, researchers look at the aging immune system in killifish, finding a feature known to exist in humans, and further digging in to the details.
Aging individuals exhibit a pervasive decline in adaptive immune function, with important implications for health and lifespan. Previous studies have found a pervasive loss of immune repertoire diversity in human peripheral blood during aging; however, little is known about repertoire aging in other immune compartments, or in species other than humans. Her...
