Granulocytopenia (a type of white blood cells )

Does the toxin that aspergillus secretes cause this condition of granulocytopenia in lupus?

Rash and inhibition of farnesyltransferase

How does the rash occur?? Is it gliotoxin directly broken down or gliotoxins's inhibition of Farnesyltransferase ?

note that gliotoxin contains a disulfide bridge
