Pyroptosis: The missing puzzle among innate and adaptive immunity crosstalk

Pyroptosis is a newly discovered programmed cell death with inflammasome formation. Pattern recognition receptors that identify repetitive motifs of prospective pathogens such as LPS of gram‐negative bacteria are crucial to pyroptosis. Upon stimulation by pathogen‐associated molecular patterns or damage‐associated molecular patterns, proinflammatory cytokines, mainly IL‐1 family members IL‐1β and IL‐18, are released through pyroptosis specific pore‐forming protein, gasdermin D. Even though IL‐1 family members are mainly involved in innate immunity, they can be factors in adaptive immunity. Given the importance of IL‐1 family members in health and diseases, deciphering the role of pyroptosis in the regulation of innate and adaptive immunity is of great importance, especially with the recent progress in identifying the exact mechanism of such a pathway. In this review, we will focus on how the innate inflammatory mediators can regulate the adaptive immune system and vice versa via pyroptosis. Review on the crosstalk among innate and adaptive immune cells as it relates to pyroptosis induction in cells responding to danger signals.
