Summary
Immune cells communicate with each other through cell-to-cell contact. Cells touch using surface receptors-this can cause a cell to carry out a function like seeking out invading bacteria. Another way cells communicate is by using chemicals (like hormones and cytokines) that are produced by different types of cells. Chemicals travel throughout the body via blood and tissues. They bind to surface receptors on certain cells to deliver a signal.
