WebFigure 9.2. Forms of chemical signaling: autocrine, gap junctions, paracrine, and endocrine. In chemical signaling, a cell may target itself (autocrine signaling), a cell connected by gap junctions, a nearby cell (paracrine signaling), or a distant cell (endocrine signaling). Paracrine signaling acts on nearby cells, endocrine signaling uses ... WebNov 7, 2024 · In Paracrine signaling, signaling can occur via gap junctions made up of connexin proteins.
