Targeting the Aging of the Immune System in the Context of Frailty

The immune system declines into a state of incapacity (immunosenescence) and chronic inflammation (inflammaging) with advancing age. Unresolved inflammatory signaling is disruptive of tissue function in many ways, from reduced stem cell activity to pathologically altered somatic cell behavior. It is thought to be important in the declining muscle mass and strength that contributes to age-related frailty. Thus addressing immune aging is a significant and important target in the treatment of aging as a whole. Frailty is a highly prevalent geriatric syndrome that has attracted significant attention from physicians and researchers due to its associated increase in vulnerability and healthcare costs, especially in the elderly population. Generally, frail patients suffer from multiple chronic diseases, with comorbidities and polypharmacy greatly challenging their health management. Gerontologists suggest that targeting the common pathogenesis of comorbidities rather than a single disease is probably a better solution for older people. Multiple factors contribute to development of frailty with advancing age, thus the therapeutic target is diversed depends on specific condition. Nutrition supplements and physical exercise are proved to be helpful in preventing and treatment of frailty, however, valid pharmaceutical intervention is scarce. Mesenchymal stem cells (MSCs) can exert regenerative effects and possess anti-inflammatory properties, offering a promising therape...
