Abstract

Interactions between cells of the immune system can lead to intercellular exchange of cell-surface molecules. Recent studies indicate that such exchange can be bidirectional when natural killer cells interact with their target cells. Sprent reviews the mechanisms involved in cell-cell molecular transfer and the receptor-ligand interactions involved.
