Allergic Drug Reactions

Allergic Drug Reactions

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 numerous...

Antigens Involved in Adaptive Immunity

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Complete antigens possess both immunogenicity and reactivity.

Drug Toxicity: Allergic Reactions

Drug Toxicity: Allergic Reactions

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 exposure to a...

Special Features of Adaptive Immunity

Special Features of Adaptive Immunity

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

T Cell Types and Functions

T Cell Types and Functions

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...

Skin Diseases and Disorders

Skin Diseases and Disorders

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...

Summary

Atopic dermatitis, a chronic inflammatory skin condition, arises from genetic, immune, and environmental factors. New therapies target innate and adaptive immunity to improve skin barrier function and regulate immune responses.

Area of Science:

Immunology
Dermatology
Genetics

Background:

Atopic dermatitis (AD), also known as eczema, is a chronic, relapsing, pruritic, and inflammatory skin disease.
The atopic eczema/dermatitis syndrome encompasses both extrinsic and intrinsic forms of AD.
AD pathogenesis involves a complex interplay of genetic predisposition, skin barrier dysfunction, and aberrant innate and adaptive immune responses.

Purpose of the Study:

To elucidate the immunopathogenesis of atopic dermatitis.
To identify key targets for novel diagnostic and therapeutic strategies in AD.

Main Methods:

Review of current understanding of AD pathogenesis.
Analysis of genetic, immunological, and environmental factors contributing to AD.
Identification of therapeutic targets within innate and adaptive immunity.

Main Results:

AD pathogenesis is multifactorial, involving genetic background, skin barrier defects, and immune dysregulation.
Innate immunity targets include enhancing skin barrier lipids, inhibiting proteases, and regulating antimicrobial peptides.
Adaptive immunity targets involve modulating immune cell responses and inducing regulatory T cells.

Conclusions:

Understanding the immunopathogenesis of AD is crucial for developing effective treatments.
Therapeutic strategies should focus on restoring skin barrier function and rebalancing aberrant immune responses in AD.
Targeting both innate and adaptive immunity offers promising avenues for managing atopic dermatitis.
