Abstract:
Viral infections pose significant threats to global public health, requiring a deep understanding of the intricate mechanisms by which individual cells respond to these infections. Conventional bulk RNA-sequencing techniques have provided valuable information on the overall host response, but they often mask the heterogeneity and dynamics of cellular responses at the single-cell level. In this study, we employ cutting-edge single-cell RNA-sequencing (scRNA-seq) and advanced computational analyses to dissect how individual cells respond to viral infection.
Using a combination of in vitro and in vivo models, we comprehensively profile gene expression changes, cellular states, and intercellular interactions during the course of viral infection. We identify distinct subpopulations of infected cells and characterize their unique transcriptional signatures, revealing a high level of cellular heterogeneity within the infected tissue. Our findings shed light on the temporal dynamics of the host response, including the initial sensing of viral invasion, the activation of antiviral defenses, and the modulation of immune cell interactions.
By integrating scRNA-seq data with spatial transcriptomics and functional assays, we further delineate the cellular composition and spatial organization of infected tissues. This integrated approach allows us to uncover specific cell-cell interactions and signaling pathways that contribute to viral pathogenesis and host defense.
Our study provides a detailed roadmap of the cellular response to viral infection, highlighting the importance of single-cell analysis in capturing the complexity of host-pathogen interactions. The novel insights gained from this work have significant implications for understanding the mechanisms of viral pathogenesis, identifying potential therapeutic targets, and developing more effective strategies for antiviral interventions.
