The extractive constituents, which are known as taste active components of fisheries products in many research works have been reviewed..This review found glutamate, glycine, alanine, arginine, proline, valine, methionine, phenylalanine, tyrosine, inosine 5’-monophosphate (IMP), adenosine 5’monophosphate (AMP), guanosine 5’-monophosphate (GMP), trimethylamine, trimethylamine oxide (TMAO), glyci...

The sense of taste is responsible for the detection and ingestion of food to cover energetic requirements in health and disease. The change in taste perception might lead to malnutrition that is usually one of the frequent causes of morbidity and mortality in patients with cancer. In this review, we summarize the mechanisms of taste perception and how they are altered in cancer. We also address...

We report the case of a 16-year-old female patient with taste impairment of the soft palate. After receiving a skull fracture due to a traffic accident, she experienced the taste of bitter chocolate. CT showed the fracture around the right temporal bone. Electrogustometry showed that the decreased sensation of taste was restricted to the right soft palate. Shirmer test showed that lacrimal secr...

The three members of the T1R class of taste-specific G protein-coupled receptors have been hypothesized to function in combination as heterodimeric sweet taste receptors. Here we show that human T1R2/T1R3 recognizes diverse natural and synthetic sweeteners. In contrast, human T1R1/T1R3 responds to the umami taste stimulus l-glutamate, and this response is enhanced by 5'-ribonucleotides, a hallm...

e-mail: [email protected] This article is based on the foreword for Symposia 15 (S15) of the 131st Annual Meeting of the Pharmaceutical Society of Japan. Fig. 1. Distribution of Nutrient Sensors in Gastrointestinal Organs Summary of current knowledge on the taste receptor gene expression is illustrated. T1Rs; T1R1/T1R3 (umami taste), T1R1/T1R3 (sweet taste); mGluRs; metabotrophic ...

Taste receptor cells detect chemicals in the oral cavity and transmit this information to taste nerves, but the neurotransmitter(s) have not been identified. We report that adenosine 5'-triphosphate (ATP) is the key neurotransmitter in this system. Genetic elimination of ionotropic purinergic receptors (P2X2 and P2X3) eliminates taste responses in the taste nerves, although the nerves remain re...

Cyclophosphamide (CYP), a commonly prescribed chemotherapy drug, has multiple adverse side effects including alteration of taste. The effects on taste are a cause of concern for patients as changes in taste are often associated with loss of appetite, malnutrition, poor recovery and reduced quality of life. Amifostine is a cytoprotective agent that was previously shown to be effective in prevent...

Necturus taste buds contain two primary cell types: taste receptor cells and basal cells. Merkel-like basal cells are a subset of basal cells that form chemical synapses with taste receptor cells and with innervating nerve fibers. Although Merkel-like basal cells cannot interact directly with taste stimuli, recent studies have shown that Merkel-like basal cells contain serotonin (5-HT), which m...

Behavioral and neural assessment tools have been used to identify cellular and molecular events that occur during taste aversion acquisition. Studies described here include an assessment of taste information processing and taste-illness association using fos-like immunoreactivity (FLI) to mark populations of cells that react strongly to the taste conditioned stimulus (CS), the illness unconditi...

Chemotherapy-induced taste disorder is one of the critical issues in cancer therapy. Bortezomib, a proteasome inhibitor, is a key agent in multiple myeloma therapy, but it induces a taste disorder. In this study, we investigated the characteristics of bortezomib-induced taste disorder and the underlying mechanism in mice. Among the five basic tastes, the sour taste sensitivity of mice was signi...
