Psychoneuroimmunology: Diabetes and Cancer

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

The Effect of Aging on Tissues

The 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...

Drug Dosing: Geriatric Patients

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

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...

Pharmacodynamics in Geriatric Patients: Effects of Age

Pharmacodynamics in Geriatric Patients: Effects of Age

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...

Autoimmune Disorders

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Summary

Immune system aging (immunosenescence) impairs cancer surveillance and promotes autoimmunity in older adults. Research explores Treg cells and Th17 lymphocytes as potential therapeutic targets for age-related immune dysfunction and cancer.

Area of Science:

Immunology
Gerontology
Oncology

Background:

Immunosenescence, the aging of the immune system, leads to decreased immune surveillance against cancer.
Aging is associated with increased risk of autoimmune diseases, often presenting atypically in the elderly.
Chronic inflammation is implicated as a risk factor for both autoimmunity and cancer in older populations.

Purpose of the Study:

To investigate the role of specific immune cell subsets in age-related immune dysfunction.
To explore the pathogenetic mechanisms linking immunosenescence, autoimmunity, and cancer.
To identify potential therapeutic targets for treating cancer in older adults.

Main Methods:

Focus on regulatory T (Treg) cells and T helper 17 (Th17) lymphocytes.
Analysis of their involvement in controlling autoimmune reactions.
Assessment of their role in cancer onset and progression.

Main Results:

Treg cells and Th17 lymphocytes are critical in immune regulation.
These cell subsets are implicated in both autoimmune phenomena and cancer development in the elderly.
Dysregulation of Treg/Th17 balance may contribute to age-related diseases.

Conclusions:

Treg cells and Th17 lymphocytes represent promising targets for future cancer therapies in older adults.
Understanding their role in immunosenescence is key to developing novel treatment strategies.
Targeting these immune cells could address both autoimmunity and cancer risk in aging individuals.
