Summary
Zinc is vital for immune function and overall health. This review explores how zinc deficiency in the elderly impacts aging and immune decline, suggesting supplementation may boost immunity.
Area of Science:
- Biochemistry
- Immunology
- Gerontology
Background:
- Zinc is crucial for numerous biochemical pathways and cellular functions, notably the immune response.
- Aging is associated with increased oxidative stress and inflammation (oxi-inflamm-aging) and a decline in immune function (immunosenescence).
- Zinc deficiency is common in older adults and mirrors some aging-related immune changes.
Purpose of the Study:
- To review the multifaceted role of zinc in human health, aging processes, and immunosenescence.
- To examine the consequences of zinc deficiency in the elderly.
- To discuss the potential of zinc supplementation for improving immune function in aging populations.
Main Methods:
- Literature review of studies on zinc's role in human health.
- Analysis of research linking zinc deficiency to aging and immunosenescence.
- Synthesis of evidence regarding zinc supplementation and immune enhancement.
Main Results:
- Zinc deficiency in the elderly is linked to detrimental changes resembling oxidative inflammatory aging and immunosenescence.
- Low zinc levels can impair various immune cell functions.
- Evidence suggests zinc supplementation may counteract some age-related immune deficits.
Conclusions:
- Zinc is essential for maintaining immune competence throughout life, particularly in aging.
- Addressing zinc deficiency in the elderly is critical for mitigating immunosenescence.
- Zinc supplementation presents a promising strategy to support immune health in older adults.

1.1K
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
4.2K
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...

01:26Factors Affecting the Risk of Infection
14.7K
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...

8.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
824
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
345
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
