Contradictory evidence for NAC?
I'm not a scientist by any means so I don't know whether I'm understanding this correctly. However, this paper seems to suggest that NAC increase the infectivity of Chlamydia infections, while inhibition of glutathione synthesis and, by extension, lower NAC consumption, helps to reduce it.
My guess is that the ability of NAC to help break the disulfde bonds of the EBs is a positive thing outside the host cell and potentially counterproductive inside it because it allows the Cpn to access the nutrients/organelles etc on which it feeds.
The trial involved C Trachomatis, not CPn, but I'm assuming the same would apply.
Hopefully, this can be explained away by a more informed member but I really believe we ought to examine counter evidence where it exists.
