Schizophrenia is a complex disorder with strong evidence implicating neurodevelopmental abnormalities in its pathophysiology. Olfactory neuroepithelial cells from patients provide a unique platform for studying neurodevelopmental processes. These cells can be cultured into neurospheres and differentiated into neurons, allowing the study of patient-...

Cannabis use disorder affects up to 42% of individuals with schizophrenia, correlating with earlier onset, increased positive symptoms, and more frequent hospitalizations. This study employed an untargeted lipidomics approach to identify biomarkers in plasma samples from subjects with schizophrenia, cannabis use disorder, or both (dual diagnosis),...

Cannabis use disorder occurs in up to 42% of subjects with schizophrenia. It has been associated with a lower age of onset of schizophrenia, more positive symptoms and a higher frequency of hospitalizations. A number of metabolomic-based studies have shown that levels of several amino acids and lipids are altered in plasma of schizophrenia patients...

The study of psychiatric and neurological diseases requires the substrate in which the disorders occur, that is, the nervous tissue. Currently, several types of human bio-specimens are being used for research, including postmortem brains, cerebrospinal fluid, induced pluripotent stem (iPS) cells, and induced neuronal (iN) cells. However, these samp...

Cannabis use disorder is frequent in schizophrenia patients, and it is associated with an earlier age of onset and poor schizophrenia prognosis. Serotonin 2A receptors (5-HT2AR) have been involved in psychosis and, like Akt kinase, are known to be modulated by THC. Likewise, endocannabinoid system dysregulation has been suggested in schizophrenia....
