Relaxin-3 (RLN3) is a neuropeptide belonging to the insulin-relaxin superfamily. RLN3-expressing neurons are predominantly located in the dorsal pons known as the nucleus incertus, and project their axons to the forebrain including the hypothalamus. RLN3 has been suggested to be involved in the stress response. In the present study, we investigated the(More)
Relaxin 3 or insulin like peptide 7 has been identified as a new member of the insulin/relaxin superfamily. We recently reported that relaxin 3 was dominantly expressed in the brain, particularly in neurons of the nucleus incertus (NI) of the median dorsal tegmental pons and that it might act as a neurotransmitter. In the present study we investigated the(More)
Relaxin-3 is a neuropeptide belonging to the relaxin/insulin superfamily. Studies using rodents have revealed that relaxin-3 is predominantly expressed in neurons in the nucleus incertus (NI) of the pons, the axons of which project to forebrain regions including the hypothalamus. There is evidence that relaxin-3 is involved in several functions, including(More)
α-Synuclein is the main component of Lewy bodies, the intraneuronal inclusion bodies characteristic of Parkinson's disease. Although α-synuclein accumulation is caused by inhibition of proteasome and autophagy-lysosome, the degradation of α-synuclein inclusions is still unknown. Formation of Lewy body-like inclusions can be replicated in cultured cells by(More)
Neurosin is one of the serine proteases predominantly expressed in the central nervous system. Neurosin is presumed to play an important role in the degradation of alpha-synuclein (alpha-syn), since a previous study showed that neurosin degrades alpha-syn, inhibits polymerization of alpha-syn in vitro, and exists in Lewy bodies. However, the details of(More)
α-Synuclein is the major pathological component of synucleinopathies including Parkinson's disease and dementia with Lewy bodies. Recent studies have demonstrated that α-synuclein also plays important roles in the release of synaptic vesicles and synaptic membrane recycling in healthy neurons. However, the precise relationship between the pathogenicity and(More)
Neurosin, also called kallikrein 6, is a trypsin-like serine protease predominantly expressed in the central nervous system. Neurosin may degrade alpha-synuclein, a major component of the Lewy bodies commonly observed in dopaminergic neurons of patients with sporadic Parkinson's disease. In the present study, we investigated the localization and proteolytic(More)
To determine the cause of a July 1996 outbreak of Escherichia coli O157:H7 among factory workers in Kyoto, Japan, we conducted cohort and case-control studies. Eating radish sprout salad during lunch at the factory cafeteria had been linked to illness. The sprouts were traced to four growers in Japan; one had been associated with an outbreak of E. coli(More)
Serotonin 2C receptors (5-HT(2C)R) are G-protein-coupled receptors with various actions, including involvement in drug addiction. 5-HT2CR undergoes mRNA editing, converting genomically encoded adenosine residues to inosines via adenosine deaminases acting on RNA (ADARs). Here we show that enhanced alcohol drinking behaviour in mice is associated with the(More)
Dopamine and serotonin (5-HT) in the nucleus accumbens (ACC) and ventral tegmental area of the mesoaccumbens reward pathways have been implicated in the mechanisms underlying development of alcohol dependence. We used a C57BL/6J mouse model with increased voluntary alcohol-drinking behavior by exposing the mice to alcohol vapor for 20 consecutive days. In(More)
