TrkB expression and dependence divides gustatory neurons into three subpopulations.

Neural Dev 2019 01 28;14(1). Epub 2019 Jan 28.

Department of Anatomical Sciences and Neurobiology, University of Louisville School of Medicine, 511 S. Floyd St., MDR Building Room 111, Louisville, KY, 40202, USA.

Background: During development, gustatory (taste) neurons likely undergo numerous changes in morphology and expression prior to differentiation into maturity, but little is known this process or the factors that regulate it. Neuron differentiation is likely regulated by a combination of transcription and growth factors. Embryonically, most geniculate neuron development is regulated by the growth factor brain derived neurotrophic factor (BDNF). Read More

State Key Laboratory of Military Stomatology & National Clinical Research Center for Oral Diseases & Shaanxi International Joint Research Center for Oral Diseases, Department of Oral Anatomy and Physiology, School of Stomatology, The Fourth Military Medical University, Xi'an, China.

Unilateral anterior crossbite (UAC) has been demonstrated to cause masseter hyperactivity via the periodontal trigeminal mesencephalic nucleus (Vme)-trigeminal motor nucleus circuit. Here, we studied activation of motor neurons of the facial nucleus (VII), hypoglossal nucleus (XII), nucleus ambiguus (Amb), and spinal nucleus of the accessory nerve (SNA) in rats with UAC via their similar connections with Vme. An anterograde tracer, biotinylated dextran amine (BDA), was injected into the Vme to identify the central axon terminals around the motor neurons of VII, XII, Amb, and SNA. Read More

Visualization of the Membranous Labyrinth and Nerve Fiber Pathways in Human and Animal Inner Ears Using MicroCT Imaging.

Front Neurosci 2018 31;12:501. Epub 2018 Jul 31.

VetImaging, VetCore Facility for Research, University of Veterinary Medicine, Vienna, Austria.

Design and implantation of bionic implants for restoring impaired hair cell function relies on accurate knowledge about the microanatomy and nerve fiber pathways of the human inner ear and its variation. Non-destructive isotropic imaging of soft tissues of the inner ear with lab-based microscopic X-ray computed tomography (microCT) offers high resolution but requires contrast enhancement using compounds with high X-ray attenuation. We evaluated different contrast enhancement techniques in mice, cat, and human temporal bones to differentially visualize the membranous labyrinth, sensory epithelia, and their innervating nerves together with the facial nerve and middle ear.

Am J Med Genet A 2018 04 12;176(4):985-991. Epub 2018 Feb 12.

Department of Pediatrics, McGill University, Montreal, Canada.

Adaptor protein complex-4 (AP-4) is a heterotetrameric protein complex which plays a key role in vesicle trafficking in neurons. Mutations in genes affecting different subunits of AP-4, including AP4B1, AP4E1, AP4S1, and AP4M1, have been recently associated with an autosomal recessive phenotype, consisting of spastic tetraplegia, and intellectual disability (ID). The overlapping clinical picture among individuals carrying mutations in any of these genes has prompted the terms "AP-4 deficiency syndrome" for this clinically recognizable phenotype. Read More

a Clinical Genetics Department, Human Genetics and Genome Research Division , National Research Centre , Cairo , Egypt.

Biallelic HMX1 mutations cause a very rare autosomal recessive genetic disorder termed as oculoauricular syndrome (OAS) because it is characterized only by the combination of eye and ear anomalies. We identified a new family bringing to three the total families reported with this disorder. Our proband presented with anteriorly protruded ears and malformed ear pinnae in association with microphthalmia, congenital cataract, microcornea, and iris and optic disc colobomata. Read More

Am J Hum Genet 2017 Oct 28;101(4):552-563. Epub 2017 Sep 28.

Neurogenetics Unit, IRCCS Santa Lucia Foundation, Rome 00143, Italy; Department of Molecular Medicine, University of Pavia, Pavia 27100, Italy. Electronic address:

The Sonic Hedgehog (SHH) pathway is a key signaling pathway orchestrating embryonic development, mainly of the CNS and limbs. In vertebrates, SHH signaling is mediated by the primary cilium, and genetic defects affecting either SHH pathway members or ciliary proteins cause a spectrum of developmental disorders. SUFU is the main negative regulator of the SHH pathway and is essential during development. Read More
