Abstract:
Aging and its associated diseases are characterized by a complex interplay of cellular dysfunction, chronic inflammation, and tissue degeneration. Dysregulated cell death and the resulting inflammatory responses are pivotal drivers of this pathological synergy. Among various cell demise pathways, programmed cell death (PCD) mechanisms, including apoptosis, necroptosis, and pyroptosis, are critical for maintaining homeostasis but can drive pathology when aberrantly activated. Crucially, they leave specific and reliable biomarkers, allowing for their distinct assessment in complex aging tissues. This review synthesizes recent insights into the intricate regulation and execution of these PCD pathways, their interconnections with inflammatory signaling, and their impact on the pathogenesis of aging and aging-related diseases. We further highlight how the integrated understanding of these cell death pathways opens avenues for targeted therapies in aging-associated disorders.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...

Molecular Factors Affecting Cell Division
Several proteins function as internal regulators to ensure each cell cycle stage is completed faithfully before proceeding to the next. Regulator molecules may act directly or influence the activity or production of other...
