/Polybia paulista/has the following distribution (from Jim Carpenter):
Brazil: Goiás, Mato Grosso, Minas Gerais, Paraná, São Paulo; Paraguay;
Argentina: Corrientes, Misiones, San Juan. /
/From Wikipedia: /"P. paulista/features a peptide Polybia-MP1 that
causes increased permeability in cells featuring phospholipids
phosphatidylserine (PS) and phosphatidylethanolamine (PE) on the outer
membrane. As cancer cells feature the PS and PE phospholipids on the
outside of the cell membrane, unlike with non-cancerous cells where the
peptides are on the inside of the cell membrane, they are susceptible to
the peptide which causes increased cell permeability to a degree that
molecules critical for cell function may leak out."
The reference given is:
It is apparently not clear yet whether this chemical can be used /in
vivo/ without adverse side-effects. As such, it may offer a mechanistic
insight into a technique that could be used to fight cancer, even if
this exact chemical cannot be incorporated into the treatment protocols.
The species is far too widespread to wipe it out, and the genus contains
nearly 100 species, with a high likelihood that they may all possess
similar (if not identical) peptides. Not something anyone is going to
control or monopolize.
