Lymphocyte subpopulations in patients with allergic rhinitis
Allergy
|October 1, 1984
Summary
Allergic rhinitis patients show reduced suppressor T8 cells, leading to a high helper/suppressor ratio. Immunotherapy normalized these parameters, suggesting a suppressor cell deficiency in allergic disease.
Area of Science:
- Immunology
- Allergy Research
Background:
- Allergic rhinitis is a common condition with complex immunological underpinnings.
- Understanding lymphocyte subset alterations is crucial for developing effective treatments.
Purpose of the Study:
- To investigate lymphocyte subpopulation differences in patients with allergic rhinitis.
- To assess the impact of immunotherapy on these lymphocyte profiles.
Main Methods:
- Flow cytometry was used to analyze B lymphocytes, total T lymphocytes, helper/inducer T cells (T4), and suppressor/cytotoxic T cells (T8).
- Comparison of lymphocyte proportions between normal controls, allergic rhinitis patients, and patients undergoing immunotherapy.
Main Results:
- Allergic rhinitis patients exhibited a significantly decreased proportion of suppressor T8 cells compared to controls.
- A high helper/suppressor T cell ratio was observed in allergic rhinitis patients.
- Immunotherapy effectively normalized the T8 cell proportion and helper/suppressor ratio.
Conclusions:
- A deficiency in suppressor T8 cells may be a key factor in the pathogenesis of allergic rhinitis.
- Immunotherapy appears to correct this suppressor cell deficiency, offering a potential therapeutic mechanism.

Overview
Allergic Drug Reactions
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 numerous...
Lymphoid Cells and Tissues
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Cells of the Adaptive Immune Response
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
