Article Abstract
Multiple sclerosis (MS) is the most common demyelinating disease caused by a multifaceted interplay of genetic predispositions and environmental factors. Most patients initially experience the relapsing-remitting form of the disease (RRMS), which is characterized by episodes of neurological deficits followed by periods of symptom resolution. However, over time, many individuals with RRMS advance to a progressive form of the disease, known as secondary progressive MS (SPMS), marked by a gradual worsening of symptoms without periods of remission. The mechanisms underlying this transition remain largely unclear, and current disease-modifying therapies (DMTs) are partially effective in treating SPMS. Age is widely acknowledged as a risk factor for the transition from RRMS to SPMS. One factor associated with aging that may influence the progression of MS is gut dysbiosis. This review discusses how aging and age-related gut dysbiosis affect the progression of MS.

Cystic fibrosis (CF) is a genetic disorder primarily known for its severe impact on lung function, but it also significantly affects the digestive system, leading to complications such as intestinal blockages, malabsorption, inflammation, and microbial dysbiosis. The study of CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) effects on intestinal physiology is critical for developing new effective treatments. This work highlights the use of the mouse intestine as a valuable model for analyzing cellular electrophysiology and CFTR function.

Gut-mitochondria is an emerging paradigm in understanding the pathophysiology of complex neuropsychiatric disorders such as Schizophrenia (SCZ). This bidirectional communication network connects the gastrointestinal microbiota with mitochondrial function and brain health, offering novel insights into disease onset and progression. SCZ, characterized by hallucinations, delusions, cognitive impairments, and social withdrawal, has traditionally been attributed to genetic and neurochemical imbalances.

The vast microbial community residing in the gut is known as the gut microbiota (GM). Alterations in the compositional equilibrium of the GM, a phenomenon termed GM dysbiosis, have been increasingly associated with the pathogenesis of various diseases, particularly neuropsychiatric disorders. The microbiota-gut-brain axis (MGBA) serves as a bidirectional communication system that connects the gut to the brain.
