Regeneration processes are the new target in looking for biological markers of psychiatric disorders.
In this study, we considered the role of stem cells and factors responsible for their trafficking in panic disorder (PD).
A group of 30 patients with panic disorder was examined and compared with a group of 30 healthy volunteers. In peripheral blood we have analysed: the number of hematopoetic stem cells – HSC (Lin−/CD45+/CD34+) and HSC (Lin−/CD45+/AC133+), the number of very small embryonic – like stem cells – VSEL (Lin−/CD45−/CD34+) and VSEL (Lin−/CD45−/CD133+) and concentration of stromal derived factor-1 (SDF-1), sphingosine-1-phosphate (S1P), and some proteins of the complement cascade.
Peripheral blood concentration of HSCs (Lin−/CD45+/AC133+) was significantly lower in PD group compared to control group, before and after antidepressant treatment. Peripheral blood concentration of VSEL (Lin−/CD45−/CD133+) was significantly lower in PD group before treatment compared to concentration after treatment. In PD group concentrations of factors involved in stem cell trafficking were statistically significant lower in PD group (before and after treatment) compared to control group.
Examination of regeneration system seems to be useful in PD diagnostics.
