S

chizophrenia (SZ) and Bipolar Disorder (BD) are diseases that can be originated during the fetal life by altered migration of

neuronal precursors and a deficient formation of synaptic contacts. Microtubules play a key role in both processes and constitute

primary cilia (PC) which is a rod like structures that senses extracellular signals in the fetal and adult brain. Recently, we described an

aberrant microtubule organization in olfactory neuronal precursors (ONE) of SZ and BD patients. In this work we explored whether

PC is present in ONE of SZ and BD patients and in healthy control subjects (HCS). Olfactory neuronal precursors were obtained by

nasal cavity exfoliation of the middle turbinate, the nasal septum and the olfactory cleft of patients recruited in the Schizophrenia

and Bipolar Disorder Clinics of the National Institute of Psychiatry and from healthy control subjects (HCS) paired by age and gender.

PC was identified by immunofluorescence staining using an anti-acetylated-tubulin antibody. The results showed that 60% of ONE

obtained from HCS (n=5) had rod-like structures with acetylated-tubulin protruding from the cell surface. By contrast, 5% of ONE

of SZ patients (n=5), and 0% of the BD (n=5) cells showed these structures. The results indicate that ciliogenesis is abated in ONE of

SZ and BD. Because PC plays a key role in neurodevelopment and ONE are mesenchymal cells, our data support the possibility that

lack of PCs in ONE may be involved in brain alterations originated at prenatal life of SZ and BD.
