I have a question with my very limited knowledge of biology:
Currently, pathogens “use” certain resources in a host, and then the host’s immune system creates antibodies that eventually kill the pathogens (or the pathogen kills the host).
The arguments are: mirror pathogens would require mirror antibodies, which is not possible for natural bodies to produce. However, this is not really a problem because our physical selves as resources would be incompatible with the needs of a mirror pathogen.
My question is: mirror or otherwise, could a pathogen “hijack” something other than usual as a resource?
Let’s say, I don’t know, Prime Pathogen A normally uses Prime Protein A, Mirror Pathogen A would require Mirror Pathogen A. Is it possible for a host to have a Prime Protein B that meets Mirror Pathogen A’s requirement–perhaps not perfectly, but “good enough” to sustain Mirror Pathogen A?
Thank you so much for taking the time and effort to answer my question and helping me understand this (or at least understand it better). The world is fascinating!
