Energy-assisted CRISPR cleavage and probiotic vesicle signaling platform: Microbiome reprogramming for homeostasis

Pathogenic infections drive microbial dysbiosis and persistent inflammation, posing therapeutic challenges due to difficulties in precise pathogen eradication and microbiome restoration. Although CRISPR-based therapeutics enable pathogen-specific antibacterial targeting, their effectiveness in treating pathogenic infections is constrained by difficulties in navigating complex microbial ecosystems, penetrating pathogenic barriers, sustaining energy-intensive intracellular cleavage, and, critically, restoring microbial balance after pathogen clearance. Here, we engineer a probiotic vesicle-synergized CRISPR platform by encapsulating gtfB-targeting CRISPR plasmids within hybrid extracellular vesicles from probiotics and pathogenic Streptococcus mutans. The pathogen-derived vesicle component enables targeted uptake by S. mutans, facilitating intracellular cleavage of the virulence gene gtfB. Vesicle-carried endogenous adenosine triphosphate (ATP) boosts CRISPR activity, amplifying targeted DNA cleavage for potent and selective pathogen elimination. Probiotic-derived vesicle components further remodel quorum-sensing networks and immunity, restoring microbial homeostasis. This probiotic vesicle-based strategy integrates ATP-enhanced CRISPR cleavage with microbiome and immune modulation, offering a next-generation therapeutic paradigm for microbiome-associated diseases.

Engineering CRISPR for Point-of-Care Tests.

CRISPR-based molecular diagnostics have emerged as powerful and programmable platforms that enable sensitive and specific detection for disease management and epidemiological surveillance. Advances in CRISPR engineering and assay design are driving the emergence of next-generation detection platforms that are highly sensitive, rapid, and amenable to field deployment. These engineering breakthroughs have the potential to reshape point-of-care tests (POCT) and transform how emerging and persistent health threats are monitored in decentralized and resource-limited settings. Herein, we systematically review the recent advancements in CRISPR engineering strategies aimed at improving detection sensitivity and specificity, eliminating the dependence on preamplification, and enabling robust POC deployment. The discussed strategies encompass both the rational engineering of CRISPR ribonucleoproteins (RNPs) and the optimization of downstream signaling modules for molecular diagnostic applications. We further highlight key challenges and future perspectives that may inspire impactful research directions and accelerate the advancement of CRISPR engineering strategies toward robust, field-deployable POCT platforms.
