Summary
Diabetes mellitus (DM) impairs immune function, increasing infection risk and accelerating immune cell aging, similar to "inflammaging". Some diabetes medications may worsen immune senescence, impacting overall health outcomes.
Area of Science:
- Immunology
- Endocrinology
- Gerontology
Background:
- Diabetes mellitus (DM) is linked to increased infection susceptibility.
- Immune dysfunction is a significant comorbidity in diabetic patients.
- Aging processes, like "inflammaging," share pathways with diabetes-induced immune issues.
Purpose of the Study:
- To review how diabetes mellitus impacts the immune system.
- To explore the connection between diabetes, "inflammaging," and age-related diseases.
- To examine the effects of diabetes on immune cell proliferation and senescence.
Main Methods:
- Literature review focusing on immunological and cellular mechanisms.
- Analysis of how diabetes affects bone marrow composition and lymphopoiesis.
- Investigation into the role of "inflammaging" pathways in diabetes.
Main Results:
- Diabetes impairs immune cell proliferation and induces senescence.
- DM alters bone marrow differentiation, favoring myeloid over lymphoid lineages.
- Diabetics exhibit reduced innate and adaptive immune responses, leading to higher infection rates and poorer vaccine efficacy.
Conclusions:
- Diabetes mellitus causes significant immune dysfunction, characterized by impaired cell proliferation and accelerated senescence.
- Diabetes-induced immune changes resemble "inflammaging," potentially increasing risk for conditions like rheumatoid arthritis and periodontitis.
- Certain diabetes medications may exacerbate immune senescence, necessitating careful consideration of their long-term effects on immune health.

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

2.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
