Regulatory T cells (Treg) are crucial for immune balance. Disrupted Treg function contributes to the inflammation seen in chronic obstructive pulmonary disease (COPD).
Area of Science:
- Immunology
- Pulmonology
Background:
- Tobacco smoke is the primary risk factor for COPD, causing airway inflammation.
- Inflammatory responses are maladaptively modulated in COPD pathogenesis.
- Regulatory T cells (Treg) are T CD4(+) lymphocytes that modulate immune responses via cytokine secretion.
Purpose of the Study:
- To systematically review the literature on Treg cells, including their ontogeny and mechanisms of action.
- To elucidate the role of Treg cells in the pathogenesis of chronic obstructive pulmonary disease (COPD).
Main Methods:
- Systematic literature search of MEDLINE, AMED, PubMed, and Scielo databases.
- Keywords included "COPD and Regulatory T cells", "Inflammation and COPD", and "Regulatory T cells".
- Inclusion of basic science articles, clinical trials, meta-analyses, and guides.
Main Results:
- Treg cells are T CD4(+) lymphocytes.
- Key functions include immune response suppression and self-antigen tolerance maintenance.
- Disruption of Treg regulatory mechanisms contributes to COPD inflammation.
Conclusions:
- Treg cells play a significant role in immune regulation.
- Dysfunctional Treg cells are implicated in the development and persistence of inflammation in COPD.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
