How does a signal from one cell influences the behavior of another cell?

Question

what are the processes associated with a development of a signal sent from one cell to the beginning of transcription in the second cell?

Answer 1

Receptor Mediated Endocytosis. (A ligand, or chemical message, sent from one cell is received by a receptor protein in the phospholipid bilayer of the cell [sticking out into the extracellular matrix]. The protein, undergoing a shape change, indicates to the cell what action to take on the inside)

Answer 2

Not sure if you want this but when I dial your cell from my cell and press send the signal from my cell is sent to your cell to ring to tell you I want to give you some information. If this is done via text message then the transcription starts when you open your in box.

I bet some Biology teacher would wet her depends if you put that on the test!
