Aspergillus Species known to produce this metabolite:
Gliotoxin posseses a spectrum of biological activities including antibacterial and antiviral activities, and it is also a potent immunomodulating agent. Gliotoxin is also an inducer of apoptotic cell death in a number of cell types, and it has been found to be associated with some diseases attributed directly or indirectly to fungal infections. It is a secondary metabolite produced by a number of Aspergillus and Penicillium species.
It is a potent immunosuppressive metabolite and brings about apoptosis in cells. Because of its effects on the immune system it may have a place in transplant surgery. There is limited evidence for its occurrence in moulded cereals. A. fumigatus is a potent pathogen which can colonise the lungs and other body tissues after ingestion of spores. There is some limited evidence that gliotoxin may be formed in situ in such circumstances.
