Summary
Inflammaging, a concept linking inflammation and aging, suggests chronic inflammation drives aging. Therapies targeting this process show promise for age-related diseases and physiological aging.
Area of Science:
- Immunology
- Gerontology
- Molecular Biology
Background:
- Aging is characterized by a chronic, low-grade inflammatory state known as inflammaging.
- Inflammaging is driven by pro-inflammatory cytokines from the innate immune system.
- This chronic inflammation may result from an evolutionary trade-off, where early-life beneficial inflammatory responses become detrimental later in life (antagonistic pleiotropy).
Purpose of the Study:
- To explain the aging process through the lens of parainflammation-driven inflammaging.
- To explore the role of the innate immune system in driving physiological and pathological aging.
- To review potential therapeutic interventions for inflammaging.
Main Methods:
- Conceptual review of inflammaging.
- Analysis of antagonistic pleiotropy theory in aging.
- Summary of proposed clinical trials.
Main Results:
- Inflammaging provides a unifying framework for understanding aging.
- Pro-inflammatory signals shift from beneficial in youth to detrimental in old age.
- Therapeutic strategies targeting inflammaging are under investigation.
Conclusions:
- Inflammaging is a key driver of both normal and pathological aging processes.
- Understanding inflammaging opens new avenues for interventions against age-related decline.
- Targeting inflammaging holds potential for treating diverse age-related conditions.

01:26Aging
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Overview
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:37Mitochondria
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,...
01:28Inflammatory Response
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
