Here we report that, in cerebrocortical nerve terminals of adult rats, the inhibition of glutamate release is mediated by mGluR7. In this preparation, the major component of glutamate release is supported by P/Q-type Ca2+ channels (72.7%). However, mGluR7 selectively reduced the release component that is associated with N-type Ca2+ channels (29.9%). Inhibition of P/Q channels by mGluR7 is not masked by the higher efficiency of these channels in driving glutamate release when compared with N-type channels. Thus, activation of mGluR7 failed to reduce the release associated with P/Q channels when the extracellular calcium concentration, ([Ca2+]o), was reduced from 1.3 to 0.5 mM. Through Ca2+ imaging, we show that Ca2+ channels are distributed in a heterogeneous manner in individual nerve terminals. Indeed, in this preparation, nerve terminals were observed that contain N-type (31.1%; conotoxin GVIA-sensitive) or P/Q-type (64.3%; agatoxin IVA-sensitive) channels or that were insensitive to these two toxins (4.6%). Interestingly, the great majority of the responses to L-AP4 (95.4%) were observed in nerve terminals containing N-type channels. This specific co-localization of mGluR7 and N-type Ca2+-channels could explain the failure of the receptor to inhibit the P/Q channel-associated release component and also reveal the existence of specific targeting mechanisms to localize the two proteins in the same nerve terminal subset."}],"day":"27","date_updated":"2021-01-12T06:58:42Z","type":"journal_article","month":"07","author":[{"first_name":"Carmelo","last_name":"Millán","full_name":"Millán, Carmelo"},{"first_name":"Enrique","last_name":"Castro","full_name":"Castro, Enrique G"},{"full_name":"Torres, Magdalena","first_name":"Magdalena","last_name":"Torres"},{"full_name":"Ryuichi Shigemoto","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","last_name":"Shigemoto","first_name":"Ryuichi"},{"first_name":"José","last_name":"Sánchez Prieto","full_name":"Sánchez-Prieto, José"}],"page":"23955 - 23962","publication":"Journal of Biological Chemistry","_id":"2633","year":"2003","publisher":"American Society for Biochemistry and Molecular Biology","quality_controlled":0,"date_published":"2003-07-27T00:00:00Z","doi":"10.1074/jbc.M211471200","publication_status":"published","citation":{"short":"C.

Combining pre-embedding immunocytochemistry with cell tracking in embryonic brain slice cultures we show that virtually all neurons (∼98%) migrating through the lower intermediate zone (LIZ) on their way from the medial ganglionic eminence to the cerebral cortex, express GABA BR1. Blockade of GABABRs with a specific antagonist, CGP52432, resulted in a concentration-dependent accumulation of these tangentially migrating neurons in the ventricular/subventricular zones (VZ/SVZ) of the cortex and fewer cells were observed in the cortical plate/marginal zone (CP/MZ) and LIZ. Moreover, they had significantly shorter leading processes compared with similar migrating cells in control slices. Electrophysiological recording in LIZ and CP cells revealed no direct effect of either CGP52432 or the GABABR agonist, baclofen, on resting membrane properties suggesting that the effect of CGP52432 on migration might be mediated through a metabotropic action or the regulation of release of factors controlling migration. These results suggest that GABABRs have an important modulatory role in the migration of cortical interneurons."}],"date_updated":"2021-01-12T06:58:43Z","day":"01","type":"journal_article","month":"09","page":"932 - 942","author":[{"first_name":"Guillermina","last_name":"López Bendito","full_name":"López-Bendito, Guillermina"},{"first_name":"Rafael","last_name":"Luján","full_name":"Luján, Rafael"},{"full_name":"Ryuichi Shigemoto","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444","last_name":"Shigemoto","first_name":"Ryuichi"},{"last_name":"Ganter","first_name":"Paul","full_name":"Ganter, Paul"},{"last_name":"Paulsen","first_name":"Ole","full_name":"Paulsen, Ole"},{"full_name":"Molnár, Zoltán","first_name":"Zoltán","last_name":"Molnár"}],"date_created":"2018-12-11T11:58:47Z","publist_id":"4264","title":"Blockade of GABAB receptors alters the tangential migration of cortical neurons","volume":13,"status":"public","citation":{"apa":"López Bendito, G., Luján, R., Shigemoto, R., Ganter, P., Paulsen, O., &#38; Molnár, Z.

Using preembedding immunohistochemical methods combined with quantitative analysis of GABAB receptor subunit immunoreactivity, this study provides a detailed description of the cellular and subcellular localization of GABAB1a/b and GABA B2 in the rat hippocampus. At the light microscopic level, an overlapping distribution of GABAB1a/b and GABAB2 was revealed in the dendritic layers of the hippocampus. In addition, expression of the GABAB1a/b subunit was found in somata of CA1 pyramidal cells and of a subset of GABAergic interneurons. At the electron microscopic level, immunoreactivity for both subunits was observed on presynaptic and, more abundantly, on postsynaptic elements. Presynaptically, subunits were mainly detected in the extrasynaptic membrane and occasionally over the presynaptic membrane specialization of putative glutamatergic and, to a lesser extent, GABAergic axon terminals. Postsynaptically, the majority of GABAB receptor subunits were localized to the extrasynaptic plasma membrane of spines and dendritic shafts of principal cells and shafts of interneuron dendrites. Quantitative analysis revealed enrichment of GABAB1a/b around putative glutamatergic synapses on spines and an even distribution on dendritic shafts of pyramidal cells contacted by GABAergic boutons. The association of GABAB receptors with glutamatergic synapses at both presynaptic and postsynaptic sides indicates their intimate involvement in the modulation of glutamatergic neurotransmission. The dominant extrasynaptic localization of GABAB receptor subunits suggests that their activation is dependent on spillover of GABA requiring simultaneous activity of populations of GABAergic cells as it occurs during population oscillations or epileptic seizures."}],"day":"03","date_updated":"2021-01-12T06:58:43Z","title":"Subcellular Localization of Metabotropic GABAB Receptor Subunits GABAB1a/b and GABAB2 in the Rat Hippocampus","volume":23,"publist_id":"4263","date_created":"2018-12-11T11:58:47Z"},{"status":"public","issue":"2","citation":{"ama":"Bell K, De Kort GJ, Steggerda S, Shigemoto R, Ribeiro Da Silva A, Cuello A.

Polar auxin transport and expression of the auxin reporter DR5-β-glucuronidase were aberrant in smt1orc.

Leaves and flowers are formed from the shoot apical meristem, triggered by the plant hormone auxin. Auxin is transported through plant tissues by specific cellular influx and efflux carrier proteins. Here we show that proteins involved in auxin transport regulate phyllotaxis. Our data indicate that auxin is transported upwards into the meristem through the epidermis and the outermost meristem cell layer. Existing leaf primordia act as sinks, redistributing auxin and creating its heterogeneous distribution in the meristem. Auxin accumulation occurs only at certain minimal distances from existing primordia, defining the position of future primordia. This model for phyllotaxis accounts for its reiterative nature, as well as its regularity and stability.","lang":"eng"}],"volume":426,"title":"Regulation of phyllotaxis by polar auxin transport","publist_id":"3707","date_created":"2018-12-11T12:00:45Z","status":"public","intvolume":"       426","extern":1,"issue":"6964","citation":{"ama":"Reinhardt D, Pesce E, Stieger P, et al.

However, the underlying mechanism is not known. Here we show that the first manifestation of the apical-basal axis in plants, the asymmetric division of the zygote, produces a basal cell that transports and an apical cell that responds to the signalling molecule auxin. This apical-basal auxin activity gradient triggers the specification of apical embryo structures and is actively maintained by a novel component of auxin efflux, PIN7, which is located apically in the basal cell. Later, the developmentally regulated reversal of PIN7 and onset of PIN1 polar localization reorganize the auxin gradient for specification of the basal root pole. An analysis of pin quadruple mutants identifies PIN-dependent transport as an essential part of the mechanism for embryo axis formation. Our results indicate how the establishment of cell polarity, polar auxin efflux and local auxin response result in apical-basal axis formation of the embryo, and thus determine the axiality of the adult plant.\n"}],"date_updated":"2021-01-12T07:40:19Z","type":"journal_article","month":"11","author":[{"full_name":"Jirí Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596","first_name":"Jirí","last_name":"Friml"},{"last_name":"Vieten","first_name":"Anne","full_name":"Vieten, Anne"},{"full_name":"Sauer, Michael","first_name":"Michael","last_name":"Sauer"},{"first_name":"Dolf","last_name":"Weijers","full_name":"Weijers, Dolf"},{"first_name":"Heinz","last_name":"Schwarz","full_name":"Schwarz, Heinz"},{"last_name":"Hamann","first_name":"Thorsten","full_name":"Hamann, Thorsten"},{"first_name":"Remko","last_name":"Offringa","full_name":"Offringa, Remko"},{"full_name":"Jürgens, Gerd","first_name":"Gerd","last_name":"Jürgens"}],"page":"147 - 153","citation":{"mla":"Friml, Jiří, et al. “Efflux Dependent Auxin Gradients Establish the Apical Basal Axis of Arabidopsis.” <i>Nature</i>, vol. 426, no. 6963, Nature Publishing Group, 2003, pp. 147–53, doi:<a href=\"https://doi.org/10.1038/nature02085\">10.1038/nature02085</a>.","ista":"Friml J, Vieten A, Sauer M, Weijers D, Schwarz H, Hamann T, Offringa R, Jürgens G. 2003.

This is largely dependent on the ability of plants to form new organs, such as lateral roots, leaves, and flowers during postembryonic development. Organ primordia develop from founder cell populations into organs by coordinated cell division and differentiation. Here, we show that organ formation in Arabidopsis involves dynamic gradients of the signaling molecule auxin with maxima at the primordia tips. These gradients are mediated by cellular efflux requiring asymmetrically localized PIN proteins, which represent a functionally redundant network for auxin distribution in both aerial and underground organs. PIN1 polar localization undergoes a dynamic rearrangement, which correlates with establishment of auxin gradients and primordium development. Our results suggest that PIN-dependent, local auxin gradients represent a common module for formation of all plant organs, regardless of their mature morphology or developmental origin.\n","lang":"eng"}],"day":"26","title":"Local, efflux-dependent auxin gradients as a common module for plant organ formation","volume":115,"date_created":"2018-12-11T12:00:46Z","publist_id":"3706"},{"status":"public","issue":"1","citation":{"ama":"Chen H, Hippenmeyer S, Arber S, Frank E.

Ligand-bound receptors catalyse GDP/GTP exchange on the G-protein α-subunit (Gα), leading to α-GTP separation from the βγ subunits and pathway activation. Activating mutations in the receptors or G proteins underlie many human diseases, including some cancers, dwarfism and premature puberty. Regulators of G-protein signalling (RGS proteins) are known to modulate the level and duration of ligand-induced signalling by accelerating the intrinsic GTPase activity of the Gα subunit, and thus reformation of the inactive GDP-bound Gα. Here we find that even in the absence of receptor, mutation of the RGS family member Sst2 (refs 6-9) permits spontaneous activation of the G-protein-coupled mating pathway in Saccharomyces cerevisiae at levels normally seen only in the presence of ligand. Our work demonstrates the occurence of spontaneous tripartite G-protein signalling in vivo and identifies a requirement for RGS proteins in preventing such receptor-independent activation."}],"type":"journal_article","month":"03","author":[{"id":"3D224B9E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8323-8353","full_name":"Daria Siekhaus","last_name":"Siekhaus","first_name":"Daria E"},{"full_name":"Drubin, David G","first_name":"David","last_name":"Drubin"}],"page":"231 - 235","publication":"Nature Cell Biology","_id":"3150","year":"2003","publisher":"Nature Publishing Group"},{"date_updated":"2021-01-12T07:41:25Z","abstract":[{"text":"Biosynthesis of most peptide hormones and neuropeptides requires proteolytic excision of the active peptide from inactive proprotein precursors, an activity carried out by subtilisin-like proprotein convertases (SPCs) in constitutive or regulated secretory pathways. The Drosophila amontillado (amon) gene encodes a homolog of the mammalian PC2 protein, an SPC that functions in the regulated secretory pathway in neuroendocrine tissues. We have identified amon mutants by isolating ethylmethanesulfonate (EMS)-induced lethal and visible mutations that define two complementation groups in the amon interval at 97D1 of the third chromosome. DNA sequencing identified the amon complementation group and the DNA sequence change for each of the nine amon alleles isolated. amon mutants display partial embryonic lethality, are defective in larval growth, and arrest during the first to second instar larval molt. Mutant larvae can be rescued by heat-shock-induced expression of the amon protein. Rescued larvae arrest at the subsequent larval molt, suggesting that amon is also required for the second to third instar larval molt. Our data indicate that the amon proprotein convertase is required during embryogenesis and larval development in Drosophila and support the hypothesis that AMON acts to proteolytically process peptide hormones that regulate hatching, larval growth, and larval ecdysis.","lang":"eng"}],"day":"01","type":"journal_article","month":"01","author":[{"first_name":"Lowell","last_name":"Rayburn","full_name":"Rayburn, Lowell Y"},{"last_name":"Gooding","first_name":"Holly","full_name":"Gooding, Holly C"},{"full_name":"Choksi, Semil P","last_name":"Choksi","first_name":"Semil"},{"full_name":"Maloney, Dhea","first_name":"Dhea","last_name":"Maloney"},{"last_name":"Kidd","first_name":"Ambrose","full_name":"Kidd, Ambrose R"},{"last_name":"Siekhaus","first_name":"Daria E","id":"3D224B9E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8323-8353","full_name":"Daria Siekhaus"},{"full_name":"Bender, Michael","last_name":"Bender","first_name":"Michael"}],"page":"227 - 237","publist_id":"3545","date_created":"2018-12-11T12:01:41Z","title":"Amontillado, the Drosophila homolog of the prohormone processing protease PC2, is required during embryogenesis and early larval development","volume":163,"year":"2003","publisher":"Genetics Society of America","publication":"Genetics","_id":"3151","publication_status":"published","quality_controlled":0,"date_published":"2003-01-01T00:00:00Z","status":"public","citation":{"ieee":"L.

Our main intuition is that any cut on a graph embedded in some continuous space can be interpreted as a contour (in 2D) or a surface (in 3D). We show how to build a grid graph and set its edge weights so that the cost of cuts is arbitrarily close to the length (area) of the corresponding contours (surfaces) for any anisotropic Riemannian metric. There are two interesting consequences of this technical result. First, graph cut algorithms can be used to find globally minimum geodesic contours (minimal surfaces in 3D) under arbitrary Riemannian metric for a given set of boundary conditions. Second, we show how to minimize metrication artifacts in existing graph-cut based methods in vision. Theoretically speaking, our work provides an interesting link between several branches of mathematics -differential geometry, integral geometry, and combinatorial optimization.

One of the major sources of difficulty is the fact that not all scene elements are visible from all cameras. In the last few years, two promising approaches have been developed 11,12 that formulate the scene reconstruction problem in terms of energy minimization, and minimize the energy using graph cuts. These energy minimization approaches treat the input images symmetrically, handle visibility constraints correctly, and allow spatial smoothness to be enforced. However, these algorithm propose different problem formulations, and handle a limited class of smoothness terms. One algorithm 11 uses a problem formulation that is restricted to two-camera stereo, and imposes smoothness between a pair of cameras. The other algorithm 12 can handle an arbitrary number of cameras, but imposes smoothness only with respect to a single camera. In this paper we give a more general energy minimization formulation for the problem, which allows a larger class of spatial smoothness constraints. We show that our formulation includes both of the previous approaches as special cases, as well as permitting new energy functions. Experimental results on real data with ground truth are also included.

This situation is common, usually due to non-lambertian scenes or to differences between cameras. We use maximization of mutual information, a powerful technique for registering images that requires no a priori model of the relationship between scene intensities in different views. However, it has proven difficult to use mutual information to compute dense visual correspondence. Comparing fixed-size windows via mutual information suffers from the well-known problems of fixed windows, namely poor performance at discontinuities and in low-texture regions. In this paper, we show how to compute visual correspondence using mutual information without suffering from these problems. Using 'a simple approximation, mutual information can be incorporated into the standard energy minimization framework used in early vision. The energy can then be efficiently minimized using graph cuts, which preserve discontinuities and handle low-texture regions. The resulting algorithm combines the accurate disparity maps that come from graph cuts with the tolerance for intensity changes that comes from mutual information."}],"date_updated":"2021-01-12T07:41:35Z","author":[{"first_name":"Junhwan","last_name":"Kim","full_name":"Kim, Junhwan"},{"last_name":"Kolmogorov","first_name":"Vladimir","id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","full_name":"Vladimir Kolmogorov"},{"first_name":"Ramin","last_name":"Zabih","full_name":"Zabih, Ramin"}],"page":"1033 - 1040","_id":"3174","year":"2003","publisher":"IEEE","quality_controlled":0,"doi":"10.1109/ICCV.2003.1238463","date_published":"2003-09-30T00:00:00Z","publication_status":"published","citation":{"chicago":"Kim, Junhwan, Vladimir Kolmogorov, and Ramin Zabih. “Visual Correspondence Using Energy Minimization and Mutual Information,” 2:1033–40.

Their construction, motivated by DES, consists of a cascade of r Feistel permutations. A Feistel permutation 1for a pseudo-random function f is defined as (L, R) → (R,L ⊕ f (R)), where L and R are the left and right part of the input and ⊕ denotes bitwise XOR or, in this paper, any other group operation on {0,1}n. The only non-trivial step of the security proof consists of proving that the cascade of r Feistel permutations with independent uniform random functions {0,1}n → {0,1}n, denoted Ψ2nr is indistinguishable from a uniform random permutation {0,1}2n → {0,1}2n by any computationally unbounded adaptive distinguisher making at most O(2cn) combined chosen plaintext/ciphertext queries for any c &lt; α, where a is a security parameter. Luby and Rackoff proved α = 1/2 for r = 4. A natural problem, proposed by Pieprzyk is to improve on α for larger r. The best known result, α = 3/4 for r = 6, is due to Patarin. In this paper we prove a = 1 -O(1/r), i.e., the trivial upper bound α = 1 can be approached. The proof uses some new techniques that can be of independent interest.
