Summary
Aging accelerates chronic disease risk by impairing immune cell function due to metabolic changes. Understanding these metabolic shifts is key to developing interventions that promote healthy aging and extend health span.
Area of Science:
- Gerontology
- Immunology
- Metabolism
Background:
- Aging is a primary risk factor for chronic diseases, marked by declining cellular and organ function.
- Metabolic changes are increasingly recognized as key drivers of age-related dysfunction, particularly impacting immune cells.
- A compromised immune system accelerates the aging process, highlighting the critical link between immunity and aging.
Purpose of the Study:
- To elucidate the metabolic perturbations associated with aging at cellular and systemic levels.
- To emphasize the intricate relationship between metabolic alterations and immunosenescence.
- To explore novel interventions for preserving immune function and enhancing health span.
Main Methods:
- Review of recent studies on aging, metabolism, and immune function.
- Analysis of cellular and systemic metabolic changes during the aging process.
- Investigation of the interplay between metabolism and immunosenescence.
Main Results:
- Metabolic dysregulation is a significant factor in age-related immune decline.
- Both intrinsic and extrinsic factors contribute to metabolic alterations during aging.
- The aging immune system exhibits impaired performance and function due to metabolic shifts.
Conclusions:
- Understanding metabolic changes in aging is crucial for mitigating age-related immune decline.
- Targeting metabolic pathways offers potential strategies to protect immune function.
- Interventions focused on metabolism may promote a longer health span and reduce chronic disease risk.

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

3.4K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

3.7K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

3.4K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
