Oro-pharyngeal mucosal microbiome alternations causing immune system dysregulation in schizophrenia.

Schizophrenia is a chronic and thoughtful psychological disorder that affects a person's thinking, feelings, and behaviours. Multi-factorial genetic, environmental, and neurological variables cause it. Recently, more research focused on the human microbiome, which alters the immune system and develops adverse health effects on the human body. The study discusses a possible relationship between the oropharyngeal microbiome and schizophrenia. According to recent studies, the oropharyngeal microbiome may alter the immune system in the human body and cause various psychiatric disorders, including schizophrenia. The oropharyngeal microbiome can cause schizophrenia either by affecting the genes, chromosomes, and immune system in the human body. Additionally, it examines the combined mechanism of how the oropharyngeal microbiome's alterations lead to genetic abnormalities and immune dysregulation in schizophrenia. By combining the various approaches, this chapter offers a comprehensive view of the oropharyngeal microbiome's role in schizophrenia and suggests that microbial alterations could serve as biomarkers or therapeutic targets for the disorder.
