Can rna self-replicate
Beyond the essential activities of viral proteins that usurp cellular components to enable replication within a cell, viruses have evolved functions that have consequences to their host on an organismal level. Once replication initiates, alphaviruses efficiently shut off host gene expression by myriad … See more The innate immune system contains several microbial recognition molecules, such as pattern recognition receptors like Toll-like receptors … See more In addition to innate immune-based sensors, host cells respond to infection by developing a stress response or by regulated cell death (apoptosis). One feature of cellular stress is the formation of stress granules … See more Studies in model organisms provide valuable insights on unpredicted features between virulent and avirulent subspecies of alphaviruses. … See more Autophagy is a homeostatic, regulated cellular process of lysosomal protein degradation and recycling that helps remove damaged components and organelles, leading to avoidance of cellular stress and death.

Self-replicating RNA derived from the genomes of positive strand RNA viruses represents a powerful tool for both molecular studies on virus biology and approaches to novel safe and effective vaccines. The following chapter summarizes the principles how such RNAs can be established and used for design of vaccines.
