The immune network theory is a theory of how the adaptive immune system works, that has been developed since 1974 mainly by Niels Jerne[1] and Geoffrey W. Hoffmann.[2][3] The theory states that the immune system is an interacting network of lymphocytes and molecules that have variable (V) regions. These V regions bind not only to things that are foreign to the vertebrate, but also to other V regions within the system. The immune system is therefore seen as a network, with the components connected to each other by V-V interactions.

I knew this was not my invention. It was too simple.

Niels and Huffman got a banana for this.
