Reprogramming tumor immune microenvironment by ultrasound‐responsive nanoplatforms for enhanced cancer immunotherapy

BMEMat, EarlyView.
Ultrasound‐responsive nanoplatforms reprogram the tumor immune microenvironment by targeting tumor cells, immune cells, and non‐immune stromal cells to enhance the efficacy of cancer immunotherapy. Abstract Cancer immunotherapy represents a significant advancement in cancer treatment by enhancing the specific recognition and elimination of cancer cells.

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

BMEMat, 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.

Enzyme activities along the kynurenine pathway in mice

, 2003
Tryptophan metabolism was studied in adult male Swiss mice by determining enzyme activities along the kynurenine pathway. The following enzymes were assayed: liver tryptophan 2,3-dioxygenase, small intestine indole 2,3-dioxygenase, liver and kidney ...

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

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 distinct profile of tryptophan metabolism along the kynurenine pathway downstream of Toll-like receptor activation in irritable bowel syndrome

Frontiers in Pharmacology, 2012
Irritable bowel syndrome (IBS), a disorder of the brain-gut axis, is characterised by the absence of reliable biological markers. Tryptophan is an essential amino acid that serves as a precursor to serotonin but which can alternatively be metabolised ...

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.

The genetic architecture of epilepsy across molecular mechanisms and clinical heterogeneity

Epilepsia Open, EarlyView.
Abstract Epilepsy comprises a highly heterogeneous group of neurological disorders unified by a persistent predisposition to recurrent seizures, yet driven by remarkably diverse genetic, molecular, and network‐level mechanisms. Advances in genomic technologies have revealed that epilepsy arises from a multilayered genetic architecture encompassing rare
