Implication

Does not yet inform clinical management of viral myocarditis; leaves open cell-free models for picornavirus assembly studies.

Key Points

The main aim is to understand the synthesis and assembly of picornaviral capsid intermediate structures using cell-free translation.
Utilized extracts from rabbit reticulocytes for cell-free translation of encephalomyocarditis RNA.
Analyzed the production of viral proteins and their ability to form capsid intermediate structures through prolonged incubation.
Investigated the requirement of proteolytic cleavage for the assembly of capsid proteins.
Viral proteins synthesized were identical to those produced during natural infection.
Assembly included detection of protomers (5S), pentamers (14S), and shell-like structures (75-85S).
Proteolytic cleavage of capsid precursor proteins is essential for successful assembly.

Intervention

Cell-free translation

Comparator

Cell-associated assembly

Outcome

Synthesis of viral proteins and assembly into viral capsid intermediate structures (protomers, pentamers, and shell-like structures)

Demonstrates that cell-free translation systems can successfully synthesize and assemble picornaviral capsid intermediate structures, highlighting the role of proteolytic cleavage.
