Type I Diabetes II: Pathophysiology01:26

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
Inflammation: Introduction01:28

Inflammation: Introduction

Inflammation is a fundamental, protective biological response of vascularized tissues to cellular injury, infection, or harmful stimuli. Its primary function is to eliminate the initial cause of injury, clear necrotic cells and damaged tissue, and initiate the necessary repair processes.Cardinal SignsAcute inflammation presents with classic signs. Redness results from vasodilation and increased blood flow. Heat is due to increased metabolism and circulation. Swelling results from the...

Overview
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Inflammatory Response01:28

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
Autoimmune Disorders01:29

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.

Area of Science:

  • Endocrinology
  • Immunology
  • Metabolic Diseases

Background:

  • Leptin is an adipokine regulating energy homeostasis, thermoregulation, bone metabolism, and immune responses.
  • Leptin has been implicated in autoimmune conditions like autoimmune encephalomyelitis, inflammatory bowel disease, and type-1 diabetes.
  • The role of leptin in non-autoimmune inflammatory diseases requires further investigation.

Purpose of the Study:

  • To review the involvement of leptin in various non-autoimmune inflammatory diseases.
  • To consolidate current knowledge on leptin's function in renal, liver, lung inflammation, atherosclerosis, metabolic syndrome, Behçet's disease, and endometriosis.

Main Methods:

  • Literature review of studies investigating leptin's role in non-autoimmune inflammatory conditions.
  • Synthesis of findings from preclinical and clinical research.

Main Results:

  • Leptin plays a significant role in the pathogenesis and progression of diverse non-autoimmune inflammatory diseases.
  • Evidence suggests leptin's involvement in renal, hepatic, and pulmonary inflammation.
  • Leptin is implicated in the development of atherosclerosis, metabolic syndrome, Behçet's disease, and endometriosis.

Conclusions:

  • Leptin is a critical mediator in non-autoimmune inflammatory diseases.
  • Targeting leptin pathways may offer therapeutic strategies for these conditions.
  • Further research is warranted to fully elucidate leptin's complex roles in inflammation.
