Azithromycin is an antibiotic medication that belongs to the macrolide family. In this trial, it is being studied for its potential effects on cellular senescence (aging of cells). While it is commonly used to treat various bacterial infections, researchers are exploring its possible new role in affecting how cells age in healthy people.

Cellular Senescence – A natural biological process where cells permanently stop dividing but remain metabolically active. These senescent cells accumulate in various tissues and organs as people age. They release inflammatory substances that affect nearby healthy cells and contribute to age-related changes in the body. This condition is characterized by specific molecular markers, including increased expression of p16INK4A protein. The process gradually develops over time and is associated with chronic low-grade inflammation, often termed “inflammaging.” Senescent cells can impact normal tissue function and repair processes.

Inflammaging – A chronic, low-grade inflammatory state that develops with advancing age. It is characterized by persistently elevated levels of inflammatory molecules in the body’s tissues and bloodstream. The condition involves a complex interaction between various immune system components and can affect multiple organ systems simultaneously. This state of chronic inflammation progresses gradually over time and is closely connected to the aging process. The condition is marked by increased levels of inflammatory markers in the blood.
