Abstract: | Biological specificity is usually described in terms of the lock-and-key metaphor. However, this metaphor is to a certain extent misleading and does not grasp the complexity underlying biological specificity. The failure of the lock-and-key metaphor makes it difficult to understand immune recognition. This is the reason why immune specificity has been described as the "Specificity Enigma." In this article, I point at three important differences between biological specificity and mechanical specificity, and suggest an alternative lens through which immune specificity can be considered. |
