The occurrence of TrkB in the murine thymus (15-day and 3-month old) was investigated by Northern blot, Western blot and immunohistochemistry. Furthermore, the thymus of 15-day-old mice carrying a non-functional mutation on trkB was analyzed. Both trkB mRNA and 145 kDa TrkB protein were detected. In addition, isolated lymphocytes and stromal cells also(More)
TrkB plays crucial roles in the development and maintenance of taste buds in mammals. In this study we investigated the presence and cell localization of Trks (TrkA, TrkB and TrkC) in taste buds of the zebrafish (Danio rerio) using Western blot and immunohistochemistry. Proteins of 140 and 145 kDa, identified as full-length TrkA and TrkB, were detected.(More)
Normal development of the lung requires coordinated activation of cascades of signaling pathways initiated by growth factors signaling through their receptors. TrkB and its ligands, brain-derived neurotrophic factor (BDNF) and neurotrophin-4, belong to the neurotrophin family of growth factors, which are expressed in a large variety of non-neuronal tissues(More)
The neuromast of the lateral line system of zebrafish has become an ideal model for the study of both developmental genetics and the vertebrate auditory system. Interestingly, the hair cells of this system have been found to selectively display immunoreactivity for S100 protein in some teleosts. In order to provide a selective marker for the sensory cells(More)
Neuregulins and their signaling ErbB receptors play a critical role during the development of the mammalian peripheral nervous system, including some kinds of mechanoreceptors such as the Pacinian corpuscles which become structurally and functionally mature postnatally. In this study, we investigated whether or not ErbBs in Pacinian corpuscles undergoes(More)
The lateral line system, formed of both superficial (pit organs) and canal neuromasts, is one of the major mechanosensory systems in fish. It has always been assumed that this system depends on neurotrophins and their cognate Trk receptors for development and maintenance, as has been shown in other mechanosensitive systems of vertebrates. However, until(More)
