Signaling

He was signaling his readiness to undertake daring tasks.

A lot of visual signaling happens on the deck of an aircraft carrier.

The handkerchiefs were tied together, and ordering the men to stand between himself and the main body, he began a series of signalings, as if communicating with some one in the ravine, from whence they had just come.

It arises as a consequence of the multiple interactions that occur after a ligand triggers a receptor to initiate a signaling cascade and it ensures that false signals do not propagate to completion.

This may be due to the fact that gp130 expression is very low on this subpopulation or that signalings from gp130 alone cannot maintain survival or proliferation in these cells.
