The echinoid immune system and the phylogenetic occurrence of immune mechanisms in deuterostomes

Immunol Today. 1992 Sep;13(9):356-62. doi: 10.1016/0167-5699(92)90172-4.

Abstract

In this article, Courtney Smith and Eric Davidson reinterpret the published data on immune function in lower deuterostomes and primitive chordates. It leads them to a new model of immune system phylogeny in which MHC-directed T-cell responses are the last to evolve and are not derived from subchordate self-nonself recognition systems.
