​​Aging-US: Preventing Age-related Chronic Inflammation and Retinal Cell Loss

Aging-US published a Special Collection on Eye Disease which included "Long-term intake of Lactobacillus paracasei KW3110 prevents age-related chronic inflammation and retinal cell loss in physiologically aged mice" which reported that age-related chronic inflammation is a major risk factor for the incidence and prevalence of age-related diseases, including infectious and neurodegenerative diseases. These authors previously reported that Lactobacillus paracasei KW3110 activated macrophages and suppressed inflammation in mice and humans. In this study, they investigated whether long-term intake of heat-killed L. paracases altered the gut microbiota in physiologically aged mice. Compared with age-matched control mice, fecal analyses of gut microbiota revealed that intake of L.paracases KW 3110 mitigated age-related changes of beneficial bacterial composition, including the Bifidobacteriaceae family. Dr. Mitsuo Maruyama and Dr. Yuji Morita said, "Aging involves a progressive decline of physiological functions in various organs, influenced by several factors, including genetic factors and environmental factors." As the aged population grows, the therapeutic and preventive approaches to decelerate senescence are of great concern. The decline in immune function has been widely examined, because it results in chronic low grade inflammation. Age-related retinal neurodegenerative diseases, such as age-related macular degeneration, are major causes of blindness in the elderly. Disruption of gut microbiota composition has been also implicated in retinal diseases through a gut-retina axis. The Maruyama/Morita Research Team concluded in their Aging-US Research Output, "the intake of L. paracasei KW3110 mitigated chronic inflammation in the intestine and retina, and reduced age-related retinal cell death. Further studies are needed to evaluate the effects in age-related senescent changes of the retina."
