Adenophorea (Nematodes)
The nematodes or roundworms constitute the phylum Nematoda. They are part of a diverse animal phylum
that live in a very large range of environments. Nematode species can be difficult to distinguish, and
although over 25,000 have been described. Its immune system is based on different signals, including a
receptor, three mitogen-activated protein kinases, and one that controls growth. Almost all components
of the nematode immune system have homologs in other organisms, including humans, and are therefore
likely of ancient evolutionary origin.
