Varicella-Zoster Virus Infection Influences Expression and Organization of Actin and α-Tubulin but Does Not Affect Lamin A and Vimentin
Bibliographic record
Abstract
OBJECTIVE: The aim of this study was to examine the effects of varicella-zoster virus (VZV) infection on the cytoskeletal components actin, lamin A, alpha-tubulin and vimentin. METHODS: The expression patterns of these four proteins during VZV infection were studied by Northern and Western blotting. The filaments were also studied in their cellular environment by immunofluorescence using confocal microscopy. Treatment with nocodazole and cytochalasin B was performed to examine the effects of the destruction of actin or tubulin networks on the VZV replicative cycle. RESULTS: The amounts of the mRNAs of actin, lamin A, alpha-tubulin and vimentin decreased slightly at 48 h post infection (p.i.) with VZV. The cellular content of the lamin A protein appeared to remain stable during the time period analyzed, whereas the amounts of actin, alpha-tubulin and vimentin decreased slightly at 24 h p.i. until the end of the viral cycle. Rearrangement of microfilaments and microtubules was observed at 24 h p.i. The addition of nocodazole or cytochalasin B decreased viral replication. CONCLUSIONS: During the VZV replicative cycle, tubulin and actin networks undergo significant changes including fiber elongation. If destroyed intentionally, viral replication is diminished, suggesting that these systems are vital for an efficient infection and viral replication.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
