A nanoplatform that induces dual‐amino acid deprivation to reverse tumor immunosuppression and enhance metabolic immunotherapy

open access: yesBMEMat, EarlyView.
ZIF‐8‐based nanoparticles co‐delivering CB‐839 (glutaminase inhibitor) and 1‐MT (IDO1 inhibitor), dual‐targeting glutamine/tryptophan metabolism to induce immunogenic cell death, activate STING, block kynurenine production, reverse immunosuppression, and enhance cancer immunotherapy to suppress primary/distant tumors.

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

open access: yesBMC 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

A link between central kynurenine metabolism and bone strength in rats with chronic kidney disease [PDF]

open access: yesPeerJ, 2017
Background Disturbances in mineral and bone metabolism represent one of the most complex complications of chronic kidney disease (CKD). Serotonin, a monoamine synthesized from tryptophan, may play a potential role in bone metabolism.

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

open access: yesEpilepsia 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 ...

Ketogenic diet for infantile epileptic spasms

open access: yesEpilepsia 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.

Kynurenine Promotes Phosphate-Induced Endothelial Calcification via Endothelial-to-Mesenchymal Transition, Osteoblastic Differentiation and AhR Activation

open access: yesToxins
In end-stage renal disease (ESRD), the accumulation of solutes normally excreted by the kidneys contributes to multiple complications, including vascular calcification (VC), a key factor in the heightened cardiovascular risk seen in these patients. Among
