Autoimmune Disorders01:29

Autoimmune Disorders

2.4K
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.

Inflammatory Response01:28

Inflammatory Response

12.5K
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,...

T Cell Types and Functions01:24

T Cell Types and Functions

3.2K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Inflammation: Introduction

84
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...

Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

50
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...

Area of Science:

  • Molecular Biology
  • Immunology
  • Genetics

Background:

  • A20 is a known inhibitor of nuclear factor-kappa B (NF-κB) signaling and possesses antiapoptotic functions.
  • Genome-wide association studies (GWASs) have identified A20 as a key susceptibility gene for inflammatory diseases.

Purpose of the Study:

  • To review recent findings on A20's molecular and biochemical mechanisms in regulating inflammatory signaling.
  • To discuss A20's role as a critical regulator of tissue homeostasis.

Main Methods:

  • Review of recent scientific literature.
  • Analysis of molecular and biochemical data on A20 function.
  • Examination of experimental evidence on A20's role in inflammatory diseases.

Main Results:

  • A20 exerts its function through ubiquitin-regulatory activities.
  • A20 modulates key inflammatory signaling cascades.
  • Experimental data confirm A20's essential role in preserving tissue homeostasis.

Conclusions:

  • A20 is a critical regulator of inflammatory responses.
  • Understanding A20's mechanisms is vital for developing therapies for inflammatory diseases.
  • A20 acts as a gatekeeper for maintaining tissue health.
