Splet01. apr. 2008 · The evidence discussed above suggests that stress granules, P-bodies and the components within them will influence viral life cycles in a variety of manners. First, the stress granule and P-body components may play important roles in host defenses against viruses by repressing the function of viral transcripts. Alternatively, the translational ... SpletPartitioning of mRNAs between polysomes, stress granules, and P bodies affects rates of translation and mRNA degradation. Host proteins within P bodies and stress granules can enhance or limit viral infection, and some viral RNAs and proteins accumulate in P bodies and/or stress granules.
