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...

Immunological Memory

Immunological Memory

Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...

Toxicokinetics: Overview

Toxicokinetics: Overview

Studies that assess how a drug is absorbed, distributed, metabolized, and excreted (ADME) at toxic doses are termed toxicokinetics. Understanding toxicokinetics helps predict adverse drug reactions (ADRs) and manage toxicity in humans.Toxicokinetics differs from pharmacokinetics mainly in the dose levels studied, with toxicokinetics focusing on higher toxic doses. The kinetics at these levels can be non-linear due to altered physiological processes. Toxicodynamics examines the relationship...

Area of Science:

Immunology
Pharmacology
Toxicology

Background:

Adverse reactions to immunostimulating drugs and adjuvants are a significant concern.
Research over two decades has illuminated the mechanisms behind these reactions.

Purpose of the Study:

To update current knowledge on immune system parameters and reactants involved in reactogenicity.
To explore toxicity mechanisms and inform the development of safer adjuvants.

Main Methods:

Review of in vitro, in vivo (animal models), and clinical data.
Analysis of immune system hyperstimulation using potent adjuvants (e.g., Freund's) and cytokines.
Examination of adjuvants used in current large-scale vaccinations.

Main Results:

Hyperstimulation models, while not directly applicable to human vaccination, provide valuable insights into toxicity.
Identified key cellular and molecular players in immune system reactogenicity.
Demonstrated the utility of animal models for understanding adjuvant-related adverse effects.

Conclusions:

Understanding immunotoxicity mechanisms is crucial for improving vaccine safety.
This knowledge aids in designing standardized models for adjuvant safety assessment.
Facilitates the potential application of novel adjuvants in human vaccines.
