The growing understanding of age-related dysfunctions offers new opportunities for intervention to improve outcomes even if the root causes of aging are not fully addressed. Research on macrophage behavior affecting the regeneration of cells in bone injuries highlights the complexity of immune system interactions with other tissues, specifically in aging and regeneration contexts. This underscores the need for selective interventions to address age-related changes in cell populations.
As the population ages, understanding the involved mechanisms of bone healing is crucial. Accumulation of senescent cells in the bone microenvironment significantly influences skeletal aging and regenerative capacity. Senescent macrophages within calluses can trigger senescence in stem cells and progenitor cells, leading to impaired fracture healing, but therapeutic approaches targeting senescent cells have shown promise for treatment in the elderly.
Rapamycin, known for its ability to slow aging and extend life in animal studies, remains a potential geroprotective drug in humans. It appears safe and shows signs of improving various bodily systems, although minimal effects were found in the muscular and neurological systems. In-depth studies of human rapamycin use are ongoing to establish its efficacy in treating aging-related physiological changes and diseases.
