Unlocking the mysteries of Alzheimer’s disease: Role of single-cell sequencing in uncovering microbial infections

Alzheimer’s disease (AD) is a neurodegenerative disorder that is characterized by the accumulation of amyloid plaques and neurofibrillary tangles in the brain. Despite decades of research, the underlying causes of AD remain poorly understood. However, recent evidence suggests that microbial infections may play a role in the development and progression of AD. With the advent of single-cell sequencing (SCS) technology, researchers now have a powerful tool to study the microbial communities in AD brains at high resolution. This review article focuses on the latest research on the role of SCS in investigating the relationship between microbial infections and AD. By enabling the identification and characterization of specific microbial species and their interactions with host cells in AD brains, SCS has provided new insights into the complex microbial landscape of AD. Furthermore, this technology has the potential to impact the diagnosis and treatment of AD by revealing new targets for therapeutic intervention. Finally, we also discussed about the challenges, limitations, ethical, and translational considerations of SCS technology, as well as future research directions in this area. The potential impact of SCS on understanding microbial infections in AD is significant, and it may lead to the development of new therapies and preventive measures for this devastating disease. In conclusion, this review highlights the important role that SCS plays in advancing our understanding of the complex microbial communities in AD and their potential involvement in disease pathogenesis.
