Identification and functional characterization of two type VI collagen receptors, alpha 3 beta 1 integrin and NG2, during avian corneal stromal development.

Interplay between low threshold voltage-gated K(+) channels and synaptic inhibition in neurons of the chicken nucleus laminaris along its frequency axis.

Activation of synaptic group II metabotropic glutamate receptors induces long-term depression at GABAergic synapses in CNS neurons.

Metabotropic glutamate receptor (mGluR)-dependent homosynaptic long-term depression (LTD) has been studied extensively at glutamatergic synapses in the CNS. However, much less is known about heterosynaptic long-term plasticity induced by mGluRs at…

Synaptic Inhibition in Avian Interaural Level Difference Sound Localizing Neurons.

Synaptic inhibition plays a fundamental role in the neural computation of the interaural level difference (ILD), an important cue for the localization of high-frequency sound. Here, we studied the inhibitory synaptic currents in the chicken posterior…

Control of a depolarizing GABAergic input in an auditory coincidence detection circuit.

Neurons in the chicken nucleus laminaris (NL), the third-order auditory neurons that detect the interaural time differences that enable animals to localize sounds in the horizontal plane, receive glutamatergic excitation from the cochlear nucleus…

Two GABAA responses with distinct kinetics in a sound localization circuit.

The temporal characteristics and functional diversity of GABAergic inhibition are determined by the spatiotemporal neurotransmitter profile, intrinsic properties of GABAA receptors, and other factors. Here, we report two distinct GABAA responses and…

Thrombospondin-4 mediates TGF-beta-induced angiogenesis.

TGF-beta is a multifunctional cytokine affecting many cell types and implicated in tissue remodeling processes. Due to its many functions and cell-specific effects, the consequences of TGF-beta signaling are process-and stage-dependent, and it is not…

Intrinsic plasticity induced by group II metabotropic glutamate receptors via enhancement of high-threshold KV currents in sound localizing neurons.

Intrinsic plasticity has emerged as an important mechanism regulating neuronal excitability and output under physiological and pathological conditions. Here, we report a novel form of intrinsic plasticity. Using perforated patch clamp recordings, we…

Regulation of glutamatergic and GABAergic neurotransmission in the chick nucleus laminaris: role of N-type calcium channels.

Neurons in the chicken nucleus laminaris (NL), the third order auditory nucleus involved in azimuth sound localization, receive bilaterally segregated (ipsilateral vs contralateral) glutamatergic excitation from the cochlear nucleus magnocellularis…

Early development of intrinsic and synaptic properties of chicken nucleus laminaris neurons.

Onset of auditory brainstem responses in chickens takes place at about embryonic day 11/12 (E11/12). We investigated early development of neuronal properties of chicken nucleus laminaris neurons, the third-order auditory neurons critically involved…

Synaptic activity-induced Ca(2+) signaling in avian cochlear nucleus magnocellularis neurons.

Neurons of the avian cochlear nucleus magnocellularis (NM) receive glutamatergic inputs from the spiral ganglion cells via the auditory nerve and feedback GABAergic inputs primarily from the superior olivary nucleus. We investigated regulation of…

Metabotropic glutamate and GABA receptors modulate cellular excitability and glutamatergic transmission in chicken cochlear nucleus angularis neurons.

Neurons in the avian cochlear nucleus angularis (NA) receive glutamatergic input from the auditory nerve, and GABAergic input from the superior olivary nucleus. Physiologically heterogeneous, NA neurons perform multiple functions including encoding…

Spatial and temporal variations in extracellular matrix of periocular and corneal regions during corneal stromal development.

The development of the avian corneal stroma occurs in discrete developmental stages. During this sequence of events, the neural crest-derived corneal fibroblast precursor cells are surrounded by distinct extracellular matrices which change both…

Type VI collagen increases cell survival and prevents anti-beta 1 integrin-mediated apoptosis.

Cell-matrix interactions are important in the development of the avian cornea. Type VI collagen is present within the periocular mesenchyme prior to the migration of cells into the corneal stroma and is abundant in the mature stroma. Whether the…

Pertubation of beta1 integrin function using anti-sense or function-blocking antibodies on corneal cells grown on fibronectin and tenascin.
