As for the mechanism of killing action, the team wasn’t able to hone in on the specifics although they had a theory. Much like any other pheromone, once cOB1 enters V583, it causes stimulation. But, instead of causing a normal increase in internal activity, this molecule sends the cell into overdrive. The result is an unwanted increase of genes promoting another internal factor to shut the cell down. The end result of this fatal attraction is cell death.
