Question

Quizplus · Accepted Answer

An autocrine signal is a signal made by a cell that affects the same cell. This type of signaling is common in immune response, inflammation, and cancer cells. Peptide signals and hormones can both be used for signaling between different cells, whereas paracrine signals are made by one cell and affect neighboring cells. Juxtacrine signals involve physical contact between cells.
