Remarkably some of these EMT-signaling pathways are upregulated by microbial pathogens, therefore suggesting that pathogens may also be considered as EMT inducers.
Most known susceptibility genes are involved in autophagy, cellular stress regulation, and microbial pathogen sensing, suggesting that cell death mechanisms might play a key role in the pathogenesis of IBD.
It is suggested that microbial pathogens in different environments are important factors that promote adaptive changes at cetacean TLR4 and new functions of some amino acid sites specialized for recognizing pathogens in dramatically contrasted environments to enhance the fitness for the adaptation and survival of cetaceans.
Previously, several groups suggested that infection by microbial pathogens induces hypermethylation of candidate genes involved in oncogenesis [ 35, 36, 24].
These results suggest a strategy commonly used by microbial pathogens to manipulate the host cellular function through histone modification and subversion of host innate immune responses for their survival or infection advantage.
In summary, the increased sensitivity to microbial pathogens and decreased sensitivity to herbivores of the hsp90.2-3 hsp90.2-3ggest an imutantnt role for Hsuggest the integranimportantveroleenvironmental stimuli into appropriate organismal responses.
Intriguingly, Leishmania amastigotes lack many of the virulence factors found in promastigotes or other microbial pathogens (cell walls, surface coats, protective pigments, and so on), suggesting that the extraordinary resilience of these pathogens is dependent on more fundamental physiological changes that confer cytoprotection against a variety of stresses.
SA-mediated defense against microbial pathogens and jasmonic acid (JA -mediated defense against insect herbivores [44] have been suggested to be antagonistically regulated [45], [46].
This suggests that there might be a selective immune response to particular microbial pathogens.
For these reasons, it has been suggested that FBA could be a good drug or vaccine target against microbial pathogens [ 44– 44].
