‘Recognition’ in the establishment of a symbiosis has been defined as the set of phenomena resulting in the expression of specificity or selectivity in associations between hosts and symbionts (Smith, 1981). The term has a somewhat different meaning in discussions of ‘cell-to-cell’ recognition, where it has the rather precise connotation of a process involving the transmission from one cell of information which elicits a response from another cell. The information is usually in the form of a particular molecule (the signal) whose binding by the ‘target’ cell constitutes ‘recognition’ and completely determines the specificity of the cell-to-cell interaction.
