STEERING THE MICROBIOTA-GUT-BRAIN AXIS BY ANTIBIOTICS TO MODEL NEURO-IMMUNE-ENDOCRINE DISORDERS.
BACKGROUND
Over the last century, animal models have been employed to study the gut-brain axis and its relationship with physiological processes, including those necessary for survival, such as food intake regulation and thermoregulation; those involved in diseases, ranging from inflammation to obesity; and those concerned to the development of neurodegenerative diseases and neuropsychiatric disorders, such as Alzheimer's disease and autism spectrum disorder, respectively.
SUMMARY
The gut microbiota has been recognized in the last decade as an essential functional component of this axis. Many reports demonstrate that the gut microbiota influences the development of a vast array of physiological processes. Experiments that use animal models to assess the effect of the gut microbiota on the brain and behavior may involve the acute or chronic administration of wide-spectrum antibiotics.
KEY MESSAGES
This narrative review summarizes the beneficial or detrimental effects of antibiotics administered prenatally or postnatally to rodents during acute or chronic periods in a wide range of protocols. These include animal models of disease and behavioral paradigms of learning and memory, anxiety, obsessive-compulsive disorder, and autism spectrum disorder. Biomarkers and behavioral assays associated with antibiotic exposure are also included in this review.
期刊介绍:
The rapidly expanding area of research known as neuroimmunomodulation explores the way in which the nervous system interacts with the immune system via neural, hormonal, and paracrine actions. Encompassing both basic and clinical research, ''Neuroimmunomodulation'' reports on all aspects of these interactions. Basic investigations consider all neural and humoral networks from molecular genetics through cell regulation to integrative systems of the body. The journal also aims to clarify the basic mechanisms involved in the pathogenesis of the CNS pathology in AIDS patients and in various neurodegenerative diseases. Although primarily devoted to research articles, timely reviews are published on a regular basis.
