Aging01:26

Aging

612
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...

Replicative Cell Senescence02:15

Replicative Cell Senescence

4.3K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

The Effect of Aging on Tissues

3.4K
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...

Mitochondria01:37

Mitochondria

19.6K
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,...

Coronary Artery Disease I: Introduction

890
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Area of Science:

  • Cardiovascular Science
  • Gerontology
  • Immunology

Background:

  • Aging is the primary unmodifiable risk factor for cardiovascular disease (CVD).
  • Cardiovascular aging involves cellular senescence and the senescence-associated secretory phenotype (SASP), contributing to inflammaging.
  • Understanding these aging mechanisms is crucial for developing interventions.

Purpose of the Study:

  • To review current knowledge on cardiovascular aging.
  • To highlight the roles of cellular senescence, SASP, and inflammaging in cardiovascular dysfunction.
  • To explore therapeutic strategies targeting aging pathways for cardiovascular health.

Main Methods:

  • Literature review of aging effects on the cardiovascular system.
  • Analysis of cellular senescence, SASP, and inflammaging.
  • Examination of biomarkers, animal models, and systems biology approaches.
  • Review of therapeutic strategies including senolytics and SASP modulators.

Main Results:

  • Cellular senescence and SASP contribute to chronic inflammation and tissue remodeling (inflammaging).
  • Macrophages play a key role in clearing senescent cells.
  • Existing drugs like metformin show potential anti-aging effects relevant to cardiovascular protection.
  • Despite progress, direct therapies for senescence and inflammaging in CVD are needed.

Conclusions:

  • Targeting cardiovascular aging, including senescence and inflammaging, is a promising strategy for long-term cardiovascular health.
  • Senolytics, SASP modulation, and anti-inflammatory/metabolic interventions show therapeutic potential.
  • Further research is needed to develop and validate therapies that directly address aging pathways to reduce CVD burden.
