Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

797
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Asthma-II: Pathophysiology and Classification

3.2K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Skin Diseases and Disorders

4.4K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Autoimmune Disorders

720
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.

T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

7.4K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...

Area of Science:

  • Immunology
  • Dermatology
  • Translational Research

Background:

  • Atopic dermatitis (AD) pathogenesis understanding has evolved beyond basic immunology.
  • Translational research in AD focuses on patient-derived data to elucidate disease mechanisms.
  • Key AD features like skin barrier defects, dysbiosis, and pruritus are linked to immune system dysfunction.

Purpose of the Study:

  • To explore how translational research, particularly through targeted therapies (biologicals), advances the understanding of atopic dermatitis (AD) pathogenesis.
  • To highlight the clinical immunology lessons learned from studying AD patients and rational therapies.
  • To connect common AD features to underlying abnormal adaptive immune responses.

Main Methods:

  • Patient-based studies of targeted therapies (biologicals).
  • Analysis of immune responses in atopic dermatitis (AD) patients.
  • Investigation of skin barrier function, skin dysbiosis, and pruritus in relation to immune mediators.

Main Results:

  • Skin-homing CLA+CD4+ memory T-cells are identified as producers of key AD mediators IL-4, IL-13, and IL-31.
  • A common abnormal adaptive immune response process underlies distinct AD features.
  • Targeted therapies provide valuable patient insights into AD immunopathogenesis.

Conclusions:

  • Translational immunology research is crucial for developing rational therapies for atopic dermatitis (AD).
  • Studying AD patients and their immune responses offers significant insights into disease mechanisms.
  • Understanding the adaptive immune response is key to managing AD effectively.
