Abstract
Background: In recent times, there has been a significant increase in studies investigating the mechanisms of microbe-induced host cell death. In addition, pathogens employ several strategies to manipulate host cell death pathways to aid their survival and spread.
Objective: We have described key differences and similarities between the mechanisms used by microbial pathogens to induce apoptotic or anti-apoptotic effects on host cells.
Review: In this review, these mechanisms were investigated by comparing apoptotic pathways in host cells infected with obligate intracellular, facultative intracellular and extracellular microbes (including bacterial, viral and fungal).
Conclusion: This review paper summarizes what we know recently know about the role of apoptosis in response to a range of microbial infections and examines how cell death pathways may influence immunity against pathogens. However, since apoptosis is also involved in host defense mechanisms against infectious agents, this phenomenon plays an important role in host-pathogen interactions. As apoptosis is a fundamental process in response to such microbial infections, it may be a therapeutic target for the treatment.
