Aging

Aging

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...

Regulation of Hematopoietic Stem Cells

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Mitochondria

Mitochondria

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,...

Multipotency of Hematopoietic Stem Cells

Multipotency of Hematopoietic Stem Cells

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Background:

The microbiome, a complex community of microorganisms, changes significantly with organismal aging.
Microbial imbalances, or dysbiosis, negatively impact the bone marrow niche, accelerating hematopoietic and immune system aging.
The gut microbiome plays a critical role in age-related hematologic changes, including clonal hematopoiesis and blood cancers.

Purpose of the Study:

To review the intricate relationship between the microbiome and the hemato-immune system during aging.
To explore how microbial dysbiosis contributes to aging-related hematologic alterations and diseases.
To discuss novel therapeutic strategies targeting dysbiosis for mitigating aging and disease progression.

Main Methods:

Literature review of studies on microbiome, aging, and the hemato-immune system.
Analysis of research on the impact of gut microbiome on age-related hematologic conditions.
Examination of current and emerging therapeutic approaches for microbiome restoration.

Main Results:

Aging is associated with significant shifts in microbiome composition and function.
Microbial dysbiosis is a key driver of bone marrow aging and immune system decline.
The gut microbiome influences the development and progression of age-related hematologic disorders like clonal hematopoiesis and blood cancers.

Conclusions:

The microbiome is a critical factor in organismal aging, particularly affecting the hemato-immune system.
Therapeutic interventions aimed at restoring microbiome balance hold potential for improving healthspan and treating age-related blood diseases.
Further research into microbiome-targeted therapies could offer new avenues for managing aging and associated pathologies.
