Detection of True IgE-expressing Mouse B Lineage Cells
Published on: December 1, 2014
Resumen
El sistema IgE, desarrollado para la defensa de los parásitos, es subvertido por antígenos inofensivos que causan alergias y asma. La comprensión de esta vía de IgE es clave para tratar estos trastornos inmunológicos prevalentes.
Área de la Ciencia:
- Inmunología Inmunología.
- Alergología Alergología.
- La medicina evolutiva es la medicina de la evolución.
Sus antecedentes:
- La inmunoglobulina E (IgE) y sus receptores evolucionaron para la defensa de los mamíferos contra las infecciones parasitarias.
- En las naciones industrializadas, las respuestas mediadas por IgE a antígenos inocuos causan alergia y asma generalizadas.
- Las enfermedades alérgicas representan una amenaza significativa para la salud pública, que excede el impacto de las infecciones parasitarias.
Objetivo del estudio:
- Investigar el papel evolutivo del sistema IgE en la defensa del huésped.
- Aclarar los mecanismos por los cuales la IgE media respuestas alérgicas a antígenos inofensivos.
- Identificar posibles objetivos terapéuticos para intervenir en la etiología de las enfermedades alérgicas.
Principales métodos:
- Revisión de la literatura evolutiva e inmunológica sobre IgE.
- Análisis de las interacciones moleculares entre IgE, sus receptores y antígenos.
- Datos epidemiológicos sobre la prevalencia de alergias y asma en las poblaciones industrializadas.
Principales resultados:
- La función protectora del sistema IgE contra los parásitos está bien establecida.
- Los antígenos inocuos pueden secuestrar la vía de IgE, lo que lleva a la sensibilización alérgica y la enfermedad.
- La prevalencia de la alergia y el asma pone de relieve una falla crítica de la regulación inmune en las poblaciones humanas modernas.
Conclusiones:
- El sistema IgE representa una espada de doble filo en la defensa inmune, capaz tanto de protección como de patología.
- Comprender la subversión de la vía IgE por los alérgenos es crucial para desarrollar tratamientos efectivos para la alergia y el asma.
- La investigación adicional sobre la biología de IgE ofrece vías prometedoras para la intervención terapéutica en enfermedades alérgicas.

Humoral Immune Responses
Overview
Antibody Structure
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.

Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

Introduction to Innate and Adaptive Immunity
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: innate and adaptive immunity.
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

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.
