Adaptive Immunity: Care for the community

  title={Adaptive Immunity: Care for the community},
  author={Margaret J. McFall-Ngai},
A memory-based immune system may have evolved in vertebrates because of the need to recognize and manage complex communities of beneficial microbes. 
Why study the evolution of immunity?
Investigations of immune recognition in nonmammalian species provide new insights into the evolution of immunity and the inner workings of the mammalian immune system. Very diverse mechanisms are
A Common Origin for Immunity and Digestion
A common origin is proposed for both the digestive and immune systems, which provides a new prism for viewing the emergence and evolution of host defense mechanisms.
Immune function keeps endosymbionts under control
Evidence is provided that the mutualism between a beetle and its bacterial endosymbiont could be mediated through the expression of host immune genes.

MHC II, a major feature of the adaptive immune system, is lacking in Atlantic cod, and there are different scenarios (metabolic cost hypothesis or functional shift hypothesis) that might explain this
Commentary on: “A common origin for immunity and digestion”
Commentary on a common origin for immunity and digestion in animals and humans and its role in infectious disease is provided by Van Niekerk, G. & Engelbrecht, A. M.
Interplay between the TH17 and TReg cell lineages: a (co-)evolutionary perspective
It is speculated that the co-evolution of these adaptive immune pathways might have given primitive vertebrates a means to benefit from the diversification of their commensal microbiota.
Towards a General Theory of Immunity?
An Immune Effector System in the Protochordate Gut Sheds Light on Fundamental Aspects of Vertebrate Immunity.
Ciona intestinalis, a filter-feeding marine protochordate that is ancestral to the vertebrate form, possesses variable region-containing chitin-binding proteins (VCBPs), a family of innate immune receptors, which recognize bacteria through an immunoglobulin-type variable region.
A new vision of immunity: homeostasis of the superorganism
The immune system is commonly perceived as an army of organs, tissues, cells, and molecules that protect from disease by eliminating pathogens, but is actually a force that shapes homeostasis within the superorganism.
