Moreover, the researchers will explore the historical context of pyroptosis, tracing its evolution and emphasizing the central role played by inflammasomes in orchestrating this captivating cellular phenomenon. Pyroptosis represents an enigmatic and dynamic process that defies conventional categorizations. Blending elements of both programmed cell death and inflammatory responses, it has piqued the curiosity of researchers across diverse disciplines ^[1]. The aim is to provide a comprehensive understanding of this intricate process, revealing its underlying mechanisms, regulatory intricacies, diverse physiological functions, and profound implications in the broader contexts of health and disease. Before the researchers dive into the depths of pyroptosis, it is essential to acknowledge its historical context. Coined in 2001 by Cookson and Brennan, the term "pyroptosis" describes a form of cell death that, unlike classical apoptosis, exhibits features of inflammation ^[2]. Since its inception, pyroptosis has sparked scientific inquiry, leading to groundbreaking discoveries that challenge conventional notions of cellular demise. Inflammasomes, multiprotein complexes, play a pivotal role in triggering and regulating pyroptosis. They orchestrate the activation of caspases and the subsequent cleavage of gasdermin proteins, culminating in the formation of membrane pores and the explosive release of cellular contents ^[1]. The interplay between inflammasomes and pyroptosis is a fascinating aspect of this phenomenon, revealing the intricate coordination between innate immunity and programmed cell death ^[3]. As we journey through the mechanisms, regulation, physiological functions, and disease implications of pyroptosis, the aim is to not only elucidate the current state of knowledge but also to inspire further exploration into this fascinating cellular process. With each revelation, we shed light on the transformative potential of pyroptosis, contributing to a deeper understanding of life, death, and the dynamic interplay that shapes the cellular tapestry of existence.
