Allergic rhinitis and CXCR3 chemokines
La Clinica Terapeutica
|February 28, 2017
Summary
Allergic rhinitis involves immune responses shifting towards type 2 dominance. T helper 1 chemokines like CXCL10 and CXCL9 may play a role in chronic allergic inflammation and treatment response.
Area of Science:
- Immunology
- Allergy Research
- Inflammation Studies
Background:
- Allergic rhinitis mechanisms involve IgE antibodies, mast cell degranulation, and histamine release.
- Immune responses in allergic individuals show a type 2-dominated shift upon allergen re-exposure.
- Elevated levels of certain chemokines (CXCL10/IP-10, CXCL9/MIG) suggest their involvement in chronic allergic inflammation.
Purpose of the Study:
- To investigate the role of T helper (Th)1 chemokines in allergic rhinitis pathogenesis.
- To explore the potential of Th1 chemokines as biomarkers for disease and treatment efficacy.
Main Methods:
- Analysis of immune responses in allergic rhinitis patients.
- Evaluation of chemokine concentrations (e.g., CXCL10, CXCL9) in nasal lavages.
- Assessment of immune-modulating drug effects on chemokine levels and symptoms.
Main Results:
- Data suggest a shift towards type 2 immune responses in allergic rhinitis.
- Elevated concentrations of CXCL10/IP-10 and CXCL9/MIG were observed in allergic patients.
- Some studies indicate increased IFN-γ and IP-10 with immune-modulating drugs correlate with symptom reduction.
Conclusions:
- Further research is required to elucidate the precise role of Th1 chemokines in allergic rhinitis.
- Th1 chemokines warrant investigation as potential biomarkers for allergic rhinitis diagnosis and treatment monitoring.

01:30Allergic Reactions: Anaphylaxis
92
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,...

01:21Chemotaxis and Direction of Cell Migration
6.0K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

01:27Allergic Drug Reactions
1.5K
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...

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
2.1K
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

4.1K
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...
