Summary
Aging causes immune system changes, leading to increased illness and inflammation, known as inflamm-aging. This review explores how leukocyte changes contribute to age-related diseases in older adults.
Area of Science:
- Immunology
- Gerontology
- Inflammation research
Background:
- Aging is linked to immune system decline.
- The role of immune changes in elderly mortality and morbidity is under investigation.
- Age-associated changes extend beyond T and B lymphocytes.
Purpose of the Study:
- To review age-dependent changes in leukocyte function.
- To explore the contribution of these changes to aging-related diseases.
- To understand the phenomenon of "inflamm-aging".
Main Methods:
- Literature review of human and animal studies.
- Analysis of age-associated changes in immune cell function.
- Synthesis of current understanding on inflamm-aging.
Main Results:
- Aging progressively dysregulates immune responses.
- Chronic low-grade inflammation ("inflamm-aging") is associated with geriatric syndromes like frailty.
- Leukocyte function changes contribute to age-related disease vulnerability.
Conclusions:
- Immune dysregulation and "inflamm-aging" are key factors in aging.
- Understanding leukocyte changes is crucial for addressing age-related diseases.
- Further research is needed to fully elucidate the impact of immune aging.

01:21Structure and Function of Leukocytes
An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.

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...
01:27Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

01:28Functions of the Lymphatic and Immune System
The lymphatic system plays a crucial role in bolstering our immune system. It consists of a network of lymphoid organs, lymph, and lymphatic vessels that provide structural and functional support in safeguarding the body against pathogens such as viruses and bacteria.
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...

01:16Primary Lymphoid Organs
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

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...
