Oligodendrocytes from human donors differ in resistance to herpes simplex virus 1 (HSV‐1)
Bibliographic record
Abstract
Primary cultures of human oligodendrocytes (HOLs) were established from six different donors. Differences in resistance to infection with herpes simplex virus 1 (HSV-1) were determined between the primary cultures of HOL in tissue culture infective dose 50 (TCID(50)), indirect immunofluoresence (IF), and serial electron microscopy (EM) studies. Virus production at different multiplicities of infection (MOIs) indicated that differences in HSV-1 replication were statistically significant and MOI-dependent. Overall, virus yield from the HOL cultures infected at an MOI of 1 increased up to 6 days postinfection (PI); no additional enhancement occurred at 7 days PI. However, differences in the replication capacity of the six HOL cultures observed at 5 days PI persisted at 6 and 7 days PI. When taken together, the results of these investigations indicate that, similar to experimental animals, resistance to HSV-1 differs between primary cultures of HOL and is donor-dependent. The results also raise the possibility that similar to experimental animals, resistance to HSV-1, mediated at the level of HOL, may be genetically determined. Furthermore, permissive infections of primary cultures of HOL were established with HSV-1 over a wide range of MOIs, similar to results obtained with viral infection of primary murine oligodendrocytes, but neither latent nor abortive infections of HOL were induced in vitro, even at very low MOIs. Resistance to HSV-1, mediated by glial cells, is a nonimmune mechanism that may influence the development of acute CNS infection in man as well as individual susceptibility to this virus.

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.
