Megjegyzések:	Pituitary adenylate cyclase activating polypeptide (PACAP) is a multifunctional and pleiotropic neuropeptide. PACAP hasdiverse effects in the endocrine system, among others, it plays important roles in oogenesis, implantation and development ofthe nervous system.However, it is not knownwhether PACAP is present in the fluids of the human reproductive organs. The aimof the present study was to determine, by means of mass spectrometry and radioimmunoassay, whether PACAP is present inhuman amniotic fluid, ovarian follicular fluid and cervico-vaginal fluid. Samples were obtained from healthy adult volunteers.Our MALDI TOF and MALDI TOF/TOF spectrometry results show that PACAP38 is present in all of the follicular fluid samples,and PACAP-like immonoreactivity was also measured by radioimmunoassay. However, we did not find the characteristic peakrepresenting the unmodified 38 amino acid form of the peptide in normal cervico-vaginal smear and amniotic fluid samples.Furthermore, we analyzed other body fluids for comparison, such as human nasal fluid, saliva and aqueous humor. PACAPwas not found in these latter samples. In summary, the present study provides evidence for the presence of PACAP in humanfollicular fluid, suggesting a role in oocyte function, but determination of the exact physiological significance awaits furtherinvestigation.
