Antigens Involved in Adaptive Immunity

489
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.

Hypersensitivities

633
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...

Asthma-I: Introduction

2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Conditioned Taste Aversion

135
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

Area of Science:

  • Immunology
  • Allergology
  • Public Health

Context:

  • Food allergy prevalence is rising globally across all age groups.
  • Accidental exposures affect approximately 45% of allergic children annually.
  • Severe reactions (anaphylaxis) leading to hospitalization and death are rare but significant concerns.

Purpose:

  • To review the current landscape of food allergy management.
  • To highlight the importance of allergen avoidance and emergency treatment education.
  • To discuss the potential role of novel therapies and regional management variations.

Summary:

  • Food allergy is a widespread, increasing chronic condition with no definitive cure.
  • Current management emphasizes strict allergen avoidance and prompt emergency treatment, including epinephrine administration.
  • While deaths from anaphylaxis are rare, factors like improved labeling and epinephrine access may contribute to stable mortality rates.
  • Omalizumab shows potential for symptom reduction in food allergy management.

Impact:

  • Understanding regional differences in epidemiology and resources is crucial for effective food allergy policies.
  • Increased awareness, diagnostic services, and epinephrine availability may be improving outcomes.
  • Further research into novel therapeutic strategies is warranted to improve patient quality of life.
