Little is known about other microbial toxins that may directly attack pancreatic beta cells and affect type 1 diabetes.
Adaptive immunity developed within an existing innate immune system to more effectively eradicate foreign antigens, whether from pathogens, malignant cells, or microbial toxins, such that repeated stimulations with foreign antigens are more efficiently excluded.
B. thuringiensis produces a toxin (Bt toxin) that causes disease in insects.
Botulinum toxin-A (BTX-A) is a type of botulinum toxin that was approved by the US Food and Drug Administration FDAA) in 1989.
"I think these authors have presented a dataset that is pretty conclusive that this is most likely a microbial toxin of some type," says environmental microbiologist Dale Griffin of the U.S. Geological Survey in St .Petersburg, Florida.
Among natural carcinogens, a prime example is the potent microbial toxin Aflatoxin B1, produced by the fungus Aspergillus flavus.
Tests attributed microbial toxin contamination in the water system to an explosion of toxic blue-green cyanobacteria algal blooms.
On the basis of this localization and the microbial colonization of the follicular infundibulum with Propionibacterium sp., Staphylococcus sp., Malassezia sp., or other members of the transient flora, one could speculate that microbial toxins or antigens could be involved in the generation of the inflammatory response.
Unfortunately, metal and metal oxide NPs have the potential to negatively impact both human health and the environment in general, e.g. by generating new classes of toxins that can adversely affect microbial communities, with knock-on effects for the whole ecosystem [32 35].
We review several potential mechanisms for microbial control over eating behavior including microbial influence on reward and satiety pathways, production of toxins that alter mood, changes to receptors including taste receptors, and hijacking of the vagus nerve, the neural axis between the gut and the brain.
