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...

Special Features of Adaptive Immunity

3.7K
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 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...

Drug Toxicity: Allergic Reactions01:30

Drug Toxicity: Allergic Reactions

209
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...

Area of Science:

  • Immunology
  • Allergy Research
  • T cell biology

Background:

  • Allergic diseases (asthma, rhinitis, eczema) are increasingly prevalent globally.
  • Regulatory T cells (Tregs) are known to prevent autoimmune diseases.
  • Interest exists in Tregs' role in preventing allergic sensitization and potential therapeutic manipulation.

Purpose of the Study:

  • To investigate the role of Tregs in preventing allergen sensitization.
  • To explore the potential of Treg manipulation for allergic disease therapy.

Main Methods:

  • Analysis of CD4+CD25+ Tregs and IL-10 Tregs in allergic vs. non-allergic individuals.
  • Induction of Tregs in animal models using inhaled antigens (high- and low-dose).
  • Assessment of Treg-induced prevention of allergen sensitization and airway inflammation.

Main Results:

  • Th2 responses to allergens are normally suppressed by CD4+CD25+ Tregs and IL-10 Tregs.
  • Treg-mediated suppression is diminished in individuals with allergic diseases.
  • Induced Tregs in animal models successfully prevented subsequent allergen sensitization and airway inflammation.

Conclusions:

  • Tregs play a critical role in suppressing allergic immune responses.
  • Decreased Treg function contributes to allergic disease development.
  • Treg induction and manipulation, alongside advancements in allergen immunotherapy, offer significant therapeutic potential for allergic diseases.
