This invention establishes a new paradigm for treatment of Parkinson's disease (PD) by eliminating senescent cells that reside in or around the site of the disease pathophysiology. Exposure of test subjects to the herbicide paraquat (PQ) increases the risk for developing Parkinson's disease. The data in this disclosure show that PQ induces a senescence arrest and SASP in astrocytes, in culture and in vivo in mice, and senescent cell markers were present in astrocytes in midbrain tissue from PD patients. In a transgenic mouse model, senescent cell ablation protected against PQ-induced PD-like neuropathology. Removal of senescent cells from affected sites using small molecule agents that specifically target senescent cells can help prevent or ameliorate signs and symptoms of the disease.

Methods are provided herein for selectively killing senescent cells and for treating senescence-associated diseases and disorders by administering a senolytic agent. Senescence-associated diseases and disorders treatable by the methods using the senolytic agents described herein include cardiovascular diseases and disorders associated with or caused by arteriosclerosis, such as atherosclerosis; idiopathic pulmonary fibrosis; chronic obstructive pulmonary disease; osteoarthritis; senescence-associated ophthalmic diseases and disorders; and senescence-associated dermatological diseases and disorders.

Foamy macrophages with senescence markers accumulate in the subendothelial space at the onset of atherosclerosis where they drive pathology by increasing expression of key atherogenic and inflammatory cytokines and chemokines. In advanced lesions, senescent cells promote features of plaque instability, including elastic fiber degradation and fibrous cap thinning, by heightening metalloprotease production. This invention provides methods and materials for treating arthritis by removing senescent cells in or around atherosclerotic plaques, thereby stabilizing the plaques, inhibiting rupture of the plaques and pathological sequelae that manifest as coronary artery disease.
