Signaling by cadherins is an example of _______ signaling.
A) autocrine
B) endocrine
C) paracrine
D) direct cell-to-cell

Question

Quizplus · Accepted Answer

Cadherins are cell adhesion molecules that facilitate direct cell-to-cell signaling by mediating the interactions between neighboring cells. Therefore, the best choice is D, direct cell-to-cell signaling. Autocrine signaling involves a cell producing and responding to signaling molecules it releases, endocrine signaling involves signaling molecules being released into the bloodstream for distant targets, while paracrine signaling involves signaling molecules being released to nearby cells.
