Neuropeptide Y- and substance P-like immunoreactivities in the guinea pig parotid gland.
These immunoreactivities were examined by double immunofluorescence, which demonstrated that many nerve fibres around the glandular acini and blood vessels contain neuropeptide Y and substance P. It appears that these substances may coexist in nerve fibres around acini, but that there may be two populations of fibres containing these peptides around the blood vessels.
