Treatment of Lung Diseases Using Pharmaceutical Agents that Eliminate Senescent Cells
Abstract
This invention is based on the discovery that many lung diseases associated with aging are mediated at least in part by cells bearing a senescent phenotype. Senescent cells accumulate with age, and express factors that contribute to the pathophysiology of age related conditions. The severity of age-related conditions typically correlates with the abundance of senescent cells: thus, clearing senescent cells can help abrogate the condition: providing symptomatic relief, and potentially inhibiting disease progression. In accordance with this invention, a family of Bcl protein inhibitors has been developed for the treatment of lung diseases. These senolytic agents have an appropriate dose and specificity profile to be effective in the clinical management of previously intractable pulmonary diseases.
