Rationale:Despite the importance of inflammation in chronic obstructive pulmonary disease (COPD), the immune cell landscape in the lung tissue of patients with mild-moderate disease has not been well characterized at the single-cell and molecular level.Objectives:To define the immune cell landscape in lung tissue from patients with mild-moderate COPD at single-cell resolution.Methods:We performed single-cell transcriptomic, proteomic, and T-cell receptor repertoire analyses on lung tissue from patients with mild-moderate COPD (n= 5, Global Initiative for Chronic Obstructive Lung Disease I or II), emphysema without airflow obstruction (n= 5), end-stage COPD (n= 2), control (n= 6), or donors (n= 4). We validated in an independent patient cohort (N= 929) and integrated with theHhip+/−murine model of COPD.Measurements and Main Results:Mild-moderate COPD lungs have increased abundance of two CD8+T cell subpopulations: cytotoxic KLRG1+TIGIT+CX3CR1+TEMRA (T effector memory CD45RA+) cells, and DNAM-1+CCR5+T resident memory (TRM) cells. These CD8+T cells interact with myeloid and alveolar type II cells viaIFNGand have hyperexpanded T-cell receptor clonotypes. In an independent cohort, the CD8+KLRG1+TEMRA cells are increased in mild-moderate COPD lung compared with control or end-stage COPD lung. Human CD8+KLRG1+TEMRA cells are similar to CD8+T cells driving inflammation in an aging-related murine model of COPD.Conclusions:CD8+TEMRA cells are increased in mild-moderate COPD lung and may contribute to inflammation that precedes severe disease. Further study of these CD8+T cells may have therapeutic implications for preventing severe COPD.
