Interaction of GABA and Excitatory Amino Acids in the Basolateral Amygdala: Role in Cardiovascular Regulation [PDF]
Activation of the amygdala in rats produces cardiovascular changes that include increases in heart rate and arterial pressure as well as behavioral changes characteristic of emotional arousal.

Kynurenic acid blocks chemogenic nociception
Abstract Previous studies have suggested a role of excitatory amino acids (EAA) in nociception. In the present study the effects of two antagonists of EAA-receptors on capsaicin-induced eye wipings were investigated. Intracisternally administered kynurenic acid, in contrast to intravenously administered MK-801, was found to effectively ...

Obesity and cancer: existing and new hypotheses for a causal connection [PDF]
Existing explanations of obesity-associated cancer emphasise direct mutagenic effects of dietary components or hormonal imbalance. Some of these hypotheses are reviewed briefly, but recent evidence suggests a major role for chronic inflammation in cancer

Improvement of kynurenine aminotransferase-II inhibitors guided by mimicking sulfate esters. [PDF]
The mammalian kynurenine aminotransferase (KAT) enzymes are a family of related isoforms that are pyridoxal 5'-phosphate-dependent, responsible for the irreversible transamination of kynurenine to kynurenic acid.

Vagus Nerve Stimulation in Refractory Epilepsy: Effects on Pro- and Anti-Inflammatory Cytokines in Peripheral Blood [PDF]
Objective: The vagus nerve has important immunological functions that may be relevant for its anticonvulsive action. We postulate that this anticonvulsive action is activated by a shift in the immune system resulting in a reduction of neurotoxic and an ...

Nicotinic α7 acetylcholine receptor-mediated currents are not modulated by the tryptophan metabolite kynurenic acid in adult hippocampal interneurons [PDF]
The tryptophan metabolite, kynurenic acid (KYNA), is classically known to be an antagonist of ionotropic glutamate receptors.

The kynurenine pathway and the brain: challenges, controversies and promises [PDF]
Research on the neurobiology of the kynurenine pathway has suffered years of relative obscurity because tryptophan degradation, and its involvement in both physiology and major brain diseases, was viewed almost exclusively through the lens of the well ...
