The identification of patients\u2019 serum proteins was carried out using mass spectrometry. For patients with paranoid schizophrenia, the proteins responsible for translation and transcription are characteristic. A significant part of the proteins of patients with simple schizophrenia regulate the cell\u2019s main metabolic and transport processes. These are proteins of the receptor system, vesicular transport, and extracellular matrix, which mainly carry out catabolic processes. The proteins of patients with schizotypal disorder mostly coincided with the classes of other patients, apart from chaperone proteins, which were not found in other studied groups. These proteins are mainly involved in anabolic processes. The main classes of proteins found in patients with APPD are responsible for the metabolism of nucleic acids. Active apoptosis processes were also revealed in these patients. These results from our basic knowledge about the molecular mechanisms of the pathogenesis of these disorders.<\/jats:p>","DOI":"10.7717\/peerj.13907","type":"journal-article","created":{"date-parts":[[2022,8,30]],"date-time":"2022-08-30T07:55:09Z","timestamp":1661846109000},"page":"e13907","source":"Crossref","is-referenced-by-count":6,"title":["Proteomic
