Cellular senescence as a source of chronic microinflammation that promotes the aging process
1Division of Cancer Cell Biology, The Institute of Medical Science, The University of Tokyo, Minato-ku, Tokyo, Japan.
Summary
Cellular senescence, characterized by permanent cell cycle arrest and inflammation, drives aging and age-related diseases. Eliminating these senescent cells can reverse age-related decline and disease.
Area of Science:
- Gerontology
- Cell Biology
- Immunology
Background:
- Aging is a complex physiological process with poorly understood mechanisms.
- Aging is a major risk factor for diseases like cancer, but the link is unclear.
- Accumulation of senescent cells contributes to age-related inflammation and organ dysfunction.
Purpose of the Study:
- To review the molecular mechanisms of cellular senescence induction.
- To explore how senescent cells contribute to age-related diseases.
- To summarize technologies for ameliorating senescent cells.
Main Methods:
- Literature review of cellular senescence.
- Analysis of molecular pathways involved in senescence.
- Examination of senolytics and other amelioration technologies.
Main Results:
- Cellular senescence involves irreversible cell cycle arrest and the senescence-associated secretory phenotype (SASP).
- Senescent cells promote chronic inflammation and tissue damage, contributing to aging.
- Eliminating senescent cells shows promise in alleviating age-related conditions.
Conclusions:
- Cellular senescence is a key driver of aging and associated pathologies.
- Targeting senescent cells offers a therapeutic strategy for age-related diseases.
- Further research into senolytics can advance geriatric medicine.

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...

8.9K
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
1.6K
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,...

01:24T Cell Types and Functions
633
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
