Cell Communication

Cell signaling is a crucial part of any communication process that governs basic cellular activities and coordinates multiple-cell actions.
It enables cells to perceive and correctly respond to their microenvironment, which is essential for development, tissue repair, immunity, and normal tissue homeostasis.

Cell-to-Cell Communication

Cell-to-cell communication is the process by which cells exchange information to coordinate their behaviors.

Why Cell Signaling?

Cell signaling is necessary for cells to perceive and respond to their microenvironment.

How Do Cells Send Signals?

Cells send signals through the transmission of molecular signals, such as proteins or hormones, from one cell to another.

Cell-Cell Communication Steps

Cells communicate through a series of steps, including signal reception, signal transduction, and response.

Quorum Sensing

Quorum sensing is a process by which cells communicate to regulate gene expression in response to changes in their population density.

Cell Signaling by Multicellular Organisms

Multicellular organisms use various types of cell signaling, including endocrine signaling, paracrine signaling, and synaptic signaling.

Local Signaling in Multicellular Organisms

Local signaling in multicellular organisms involves the transmission of signals between cells that are in close proximity to each other.
