Abstract: Disclosed are agents (e.g., peptides, polypeptides, proteins, small molecules, antibodies, and antibody fragments that target senescent cells) and methods of their use for imaging senescent cells in vivo and for treating or preventing cancer, age-related disease, tobacco-related disease, or other diseases and disorders related to or caused by cellular senescence in a mammal. The methods include administering one or more of the agents of the invention to a mammal, e.g., a human. The agents, which specifically bind to senescent cells, can be labeled with a radioactive label or a therapeutic label, e.g., a cytotoxic agent.

Abstract: The present disclosure provides conjugates, systems, devices, and methods for detecting cellular redox state. In one aspect, for example, a conjugate for detecting cellular redox state can include a first segment including a cell penetrating peptide conjugated to a first detection molecule, and a second segment including a cargo peptide conjugated to a second detection molecule, wherein the first segment and the second segment are coupled together by a redox-sensitive linkage, and wherein the first detection molecule and the second detection molecule have properties that allow linked proximity detection. In one specific example, the first detection molecule and the second detection molecule include a fluorophore/quencher pair.
