Summary
Allergen-specific immunoglobulin E (IgE) binds to mast cells and basophils, triggering allergic inflammation upon re-exposure to allergens. Eosinophils are recruited to sites of allergic reactions.
Area of Science:
- Immunology
- Allergy Research
Background:
- Allergic inflammation involves key immune cells like IgE, mast cells, basophils, and eosinophils.
- Allergen-specific IgE binds to mast cells and basophils, initiating allergic responses.
- Eosinophils are recruited to sites of allergic inflammation.
Purpose of the Study:
- To elucidate the roles of IgE, mast cells, basophils, and eosinophils in allergic inflammation.
- To describe the mechanism of IgE-mediated allergic reactions.
Main Methods:
- Review of immunological pathways in allergic inflammation.
- Analysis of cellular interactions and mediator release.
Main Results:
- Immunoglobulin E (IgE) plays a central role in allergic reactions.
- Mast cells and basophils, upon IgE aggregation by allergens, release inflammatory mediators.
- Eosinophils are attracted to these inflammatory sites.
Conclusions:
- IgE, mast cells, basophils, and eosinophils are critical components of the allergic inflammatory cascade.
- Understanding these cellular interactions is key to developing allergy treatments.

01:15Differentiation of Common Myeloid Progenitor Cells
3.1K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

01:30Classification of Leukocytes
9.0K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

01:28Cells of the Innate Immune Response
8.4K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

01:30Allergic Reactions: Anaphylaxis
280
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,...

01:28Asthma I: Introduction
112
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
