Intestinal microbiome alterations in pediatric epilepsy: Implications for seizures and therapeutic approaches

Epilepsia Open, EarlyView.
Abstract The intestinal microbiome plays a pivotal role in maintaining host health through its involvement in gastrointestinal, immune, and central nervous system (CNS) functions. Recent evidence underscores the bidirectional communication between the microbiota, the gut, and the brain and the impact of this axis on neurological diseases, including ...

A history of suicide attempts among individuals with schizophrenia is associated with tryptophan degradation via the salivary kynurenine pathway

BMC Psychiatry
Background Tryptophan, an essential precursor metabolite within the kynurenine pathway, has been implicated in the neurobiological mechanisms underlying both schizophrenia and associated suicidality. Despite this link, the lack of validated biomarkers to

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

Development of a Fluorescent Chemosensor for the Detection of Kynurenine

, 2016
Kynurenine, a metabolite of tryptophan, is known to contribute to cancer progression when overproduced. A method for facile fluorescent sensing of kynurenine using sensor 1 has been developed.

The kynurenine pathway.

, 2020
The kynurenine pathway (KP) is the major route of Trp degradation. The first step is the formation of formylkynurenine from Trp, catalysed by hepatic tryptophan 2,3-dioxygenase (TDO), predominantly expressed in the liver, or indoleamine-2,3-dioxygenase ...

Kynurenine may directly interact with GABA receptors in rat brain

, 1985
Previous studies have shown that kynurenine may have convulsant activity. In the present investigation the intracerebroventricular injection of L- but not D-kynurenine induced convulsions in the rat. In vitro, L- but not D-kynurenine was able to displace

The gut microbiome and drug‐resistant epilepsy: Microbiome–antiseizure medication interactions and implications for pharmacoresistance

Epilepsia Open, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects approximately one‐third of patients with epilepsy and represents a major unmet clinical need. While traditional hypotheses of pharmacoresistance have focused on alterations in drug targets, efflux transporter overexpression, and intrinsic disease severity, the gut microbiome has recently emerged as a ...

Kynurenine metabolism in health and disease.

, 2010
Kynurenine is a small molecule derived from tryptophan when this amino acid is metabolised via the kynurenine pathway. The biological activity of kynurenine and its metabolites (kynurenines) is well recognised.

Urinary and Faecal Amino‐Acids as Biomarkers for Colorectal Neoplasia in Lynch Syndrome—A Prospective Longitudinal Study

International Journal of Cancer, EarlyView.
ABSTRACT In Lynch syndrome, colonoscopy surveillance for colorectal cancer (CRC) is burdensome and post‐colonoscopy CRCs still occur. Unlike the faecal immunochemical test (FIT), gut metabolomic alterations including amino‐acids have shown potential as non‐invasive biomarkers for detecting both advanced and non‐advanced sporadic colorectal neoplasia ...

System‐Local Axes and Metabolic Reprogramming From Health to Response in House Dust Mite‐Specific Subcutaneous Immunotherapy for Allergic Rhinitis

iMetaMed, EarlyView.
This study delineated nasal‐plasma metabolic reprogramming in house dust mite‐allergic rhinitis (HDM‐AR) and subcutaneous immunotherapy (SCIT) response, showing compartment‐specific signatures dominated by nasal lipid‐redox and plasma nucleotide‐NAD+ axes and across the HC–HDM‐AR–SCIT response continuum, dual‑compartment metabolites exhibited ...
