Can anyone give information on up-regulation of Parasite (by the host) that
ensures survival? It is written that Toxoplasma down-regulates and forms
tissue cysts when the Host produces an immune response. If the parasite did
not do this, it could kill the host quickly (down-regulation increases
Toxoplasma's opportunity to infect another host). Is there an example of
the opposite = the parasite up-regulates (caused by the host's immune
response or some other reaction by the host) and its survival/reinfection
successes are increased. Many thanks.
