Bacterial Exotoxins and the Inflammasome
The inflammasomes are intracellular protein complexes that play an important role in innate immune sensing. Activation of inflammasomes leads to activation of caspase-1 and maturation and secretion of the pro-inflammatory cytokines interleukin (IL)-1β and IL-18. In certain myeloid cells, this activation can also lead to an inflammatory cell death (pyroptosis). Inflammasome sensor proteins have ...
متن کاملBacterial pyrogenic exotoxins as superantigens.
The recent discovery of the mode of interaction between a group of microbial proteins known as superantigens and the immune system has opened a wide area of investigation into the possible role of these molecules in human diseases. Superantigens produced by certain viruses and bacteria, including Mycoplasma species, are either secreted or membrane-bound proteins. A unique feature of these prote...
متن کاملCytidylyl cyclase activity of bacterial exotoxins
3',5'-Cyclic adenosine monophosphate (cAMP) and 3',5'cyclic guanosine monophosphate (cGMP) are key second messengers for a wide variety of mammalian cellular processes. The natural occurrence of a third cyclic nucleotide, 3',5'-cyclic cytidine monophosphate (cCMP) had been discussed very controversially 30–35 years ago [1-3], but later, cCMP was identified unambiguously in various mammalian tis...

متن کاملInactivation of Bacterial Exotoxins and Endotoxin by Iron
After incubation with various agents in vitro, the lethal effects of aqueous solutions of Cl. perfringens alpha toxin, C. diphtheriae toxin, and E. coli endotoxin were tested in mice, guinea pigs, and rabbits, respectively. Iron, copper, cysteine, ascorbic acid, and versene counteracted the lethal effects of alpha toxin in mice, while magnesium, manganese, zinc, and citrate did not. Iron also c...
