Antigens Involved in Adaptive Immunity

1.9K
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.

Allergic Reactions: Anaphylaxis

207
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin,...

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...

Antibody Structure

68.6K
Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Summary
This summary is machine-generated.

Certain proteins act as allergens, triggering allergic diseases by stimulating innate immunity. These allergens interact with immune cells, promoting allergic sensitization and disease development.

Area of Science:

  • Immunology
  • Allergy Research
  • Molecular Biology

Background:

  • Allergic diseases result from immune responses to specific allergens.
  • A limited number of proteins from plant and animal proteomes function as allergens.
  • Allergens are categorized by shared structural, biochemical, and functional characteristics.

Purpose of the Study:

  • To explore the mechanisms by which allergens interact with innate immune cells.
  • To elucidate the role of intrinsic adjuvant properties of allergens in immune stimulation.
  • To understand how these interactions contribute to allergic sensitization and disease.

Main Methods:

  • Review of existing scientific literature on allergens and innate immunity.
  • Analysis of how allergens bind to pattern recognition receptors on immune cells.
  • Investigation of allergen proteolytic activities and induction of type 2 innate lymphoid cells (ILC2).

Main Results:

  • Some allergens possess inherent adjuvant properties that enhance innate immune responses.
  • Allergens interact with dendritic cells and epithelial cells via pattern recognition receptors.
  • Allergen interactions can induce type 2 innate lymphoid cells (ILC2), promoting allergic inflammation.

Conclusions:

  • Intrinsic adjuvant properties of allergens are key contributors to allergenicity.
  • Allergen interactions with innate immune cells are crucial for allergic sensitization.
  • Understanding these mechanisms can inform strategies for managing allergic diseases.
