Book excerpt: We have previously postulated that wild-type Herpes Simplex Virus type I (HSV-1) infections are characterized by the presence of a fusion factor and a fusion inhibitor activity. The fusion inhibitor presumably is dominant so that a small fraction of cells fuse in a typical wild-type infection. Furthermore, the syn mutants isolated in our laboratory are thought to cause extensive cell fusion because the production of active fusion inhibitor in cell membranes is delayed. If mutations existed that altered both the fusion factor and fusion inhibitor activity then separate viruses containing these two mutations might be able to complement each other, each supplying the defective gene product missing in the other virus. This would produce a wild type and not a syncytial mutant response. Complementation tests between two viruses, tsB5 and syn 20, which are thought to contain defects in the production of active fusion factor and fusion inhibitor activity, respectively, were done. A wild-type response was observed indicating that the mutations affecting fusion were in two separate genes.

Labeled, sparse, infected cells were surrounded by unlabeled, excess, uninfected (or infected) cells to determine if fusion inhibition is active when present in the same cell as fusion factor, when present in cells that do not contain fusion factor, or in both situations. We found that wild type infected cells fuse to the same extent with each other as with uninfected cells. Therefore fusion inhibitor is active when present in the same cell as fusion factor. Other experiments indicate that the inhibition activity can also cause a small decrease of fusion when fusion factor and fusion inhibitor are present in different, but neighboring, cells. Marked variations are found in the capacity of different cell types, such as human embryonic lung (HEDL) and HEp-2 to support fusion by particular syn mutants. The difference in fusion capacity of the two cell types may be due to a difference in a cellular factor affecting the activity of viral, fusion-associated molecules, and not to cell surface differences of the uninfected cells.
