How do growth cones interact with attractive and repulsive cues in their environment?

Question

Quizplus · Accepted Answer

Receptor proteins in the filopodia membrane interact with cues in the environment. Growth cones have receptor proteins on their filopodia membrane that allow them to respond to attractive and repulsive cues in their environment. When an attractive cue binds to its receptor, it triggers a signaling pathway that leads to the growth cone being directed towards the source of the cue. In contrast, when a repulsive cue binds to its receptor, it triggers a signaling pathway that either causes the growth cone to change direction or retract away from the source of the cue.
