Autoimmune Disorders01:29

Autoimmune Disorders

2.2K
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.

Skin Diseases and Disorders

6.2K
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...

Hypersensitivities

8.4K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

T Cell Types and Functions01:24

T Cell Types and Functions

3.3K
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...

Allergic Drug Reactions01:27

Allergic Drug Reactions

1.6K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Drug Toxicity: Allergic Reactions01:30

Drug Toxicity: Allergic Reactions

152
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Summary
This summary is machine-generated.

Autoallergy, where autoimmunity meets atopic disease with IgE, can worsen chronic atopic dermatitis (AD). Understanding autoallergen mechanisms and T cell roles is key to managing AD.

Area of Science:

  • Immunology
  • Dermatology
  • Allergology

Background:

  • Autoallergy, defined as autoimmunity co-occurring with atopic disease, is characterized by antigen-specific IgE.
  • This phenomenon is implicated in the chronification of atopic dermatitis (AD) and influences the immune response in chronic AD.
  • This review focuses on recent advancements in understanding autoallergic inflammation within AD.

Approach:

  • The review examines various mechanisms contributing to the allergenicity of autoallergens.
  • Discussion includes intrinsic immunomodulatory functions of autoallergens.
  • Molecular mimicry as a factor influencing the allergenic potential of autoallergens is also explored.

Key Points:

  • Autoallergy involves antigen-specific IgE and is linked to chronic atopic dermatitis (AD).
  • Mechanisms like intrinsic functions and molecular mimicry contribute to autoallergenicity.
  • The role of specific T cells in autoallergic inflammation in AD is a critical area of investigation.

Conclusions:

  • Autoallergy plays a significant role in the pathogenesis and chronification of atopic dermatitis.
  • Further research into autoallergen mechanisms and T cell responses is crucial for developing targeted therapies for AD.
