Dendritic cells (DC) are well known for their capacity to induce immune responses and there is also accumulating evidence of their ability to interact with various cell types of the innate system, such as NK, NKT or TCR gamma-delta cells. These interactions are bi-directional, mediated by soluble or cell surface molecules and have been mainly described in the context of immune responses to infectious agents and tumors. NK, NKT or TCR gamma-delta cells induce the maturation of DC, as shown by the increased expression of CD86, IL12 production and priming of T cell responses. On the other hand, mature DC have the ability to activate NK, NKT or TCR gamma-delta cells for sustained innate immune responses and activated NK cells may kill immature DC. In addition, DC and NK or TCR gamma-delta cells share similar functions such as cytotoxic and antitumor activity, interferon production and antigen presentation capacity. [less ▲]

We explore the flux-jump regime in type-II Pb thin films with a periodic array of antidots by means of magneto-optical measurements. A direct visualization of the magnetic flux distribution allows us to identify a rich morphology of flux penetration patterns. We determine the phase boundary H-*(T) between dendritic penetration at low temperatures and a smooth flux invasion at high temperatures and fields. For the whole range of fields and temperatures studied, guided vortex motion along the principal axes of the square pinning array is clearly observed. In particular, the branching process of the dendrite expansion is fully governed by the underlying pinning topology. A comparative study between macroscopic techniques and direct local visualization sheds light onto the puzzling T- and H-independent magnetic response observed at low temperatures and fields. Finally, we find that the distribution of avalanche sizes at low temperatures can be described by a power law with exponent tau similar to 0.9(1). [less ▲]

The human spinal cord was studied with the Golgi method from 26 weeks gestational age onto adult life. Impregnated neurons were analyzed morphometrically by an adaptation of Sholl's concentric circle method in order to specify dendritic geometry, ramification richness and branching pattern. Neurons were classified according to Rexed's laminar scheme, identified on adjacent Nisslstained sections. The following features were found to be characteristic of the dorsal horn laminae. Lamina I is formed of a uniform population of large, poorly ramified neurons. Their main dendritic domaine is disk-shaped in the tangential plane with a mean diameter of about 800 micrometers. Orthogonal, spiny dendrites penetrating into lamina II are numerous even in adult material. Four cell types, all lying in the sagittal plane, are found in lamina II. (1) "Islet cells' (about 30% of impregnated neurons) have a rostrocaudal, cylindrical dendritic domaine with a long axis of +/- 600 micrometers, a few scattered spines and a richly branched axonal network, confined to the dendritic territory. They are more numerous in the central part of lamina II. A few islet cells have two axons. (2) "Filamentous cells' (about 20%), so called because of their multiple filiform, spiny dendrites, are vertico-sagittally oriented. Their soma is located in inner or outer lamina II, their dendritic tree, trapezoid of about 280 micrometers in height, being dorsal or ventral. The axon emits some collaterals in the vicinity of the dendritic tree, then it penetrates into lamina I or Lissauer's tract. (3) "Curly cells' (about 10%) have a complex, twisted, spine-rich dendritic tree. The dendritic domaine can be schematized by a sagittal disk with a diameter of about 200 micrometers, the cell body being eccentric. Curly cells are mainly found in outer lamina II. Their axon penetrates into lamina I or Lissauer's tract. (4) "Stellate cells' (about 40%) are multipolar neurons preferentially found in inner lamina II. They have straight, spine-poor dendrites, which cover a large (longest diameter ca. 500 micrometers), elliptical territory extending into laminae I and III. Their axon gives longitudinal collaterals to lamina II before penetrating deeply into laminae III and IV. Lamina III contains a mixed population of "antenna-like neurons' with a vertical, cone-shaped dendritic domaine and "radiate cells' characterized by a small, spherical territory. All lamina IV neurons are medium or large sized "antenna-like neurons' whose dorsally oriented, cone-shaped dendritic domaine may have a height of 1000 micrometers. It can be concluded that the dorsal horn of the human spinal cord has several distinct dendroarchitectonic features, different from those reported in animals. The possible functional implication of some dendritic features is examined and a laminar dendroarchitectonic scheme of the human cord is proposed as a morphological tool for future neuroanatomical and neuropathological studies.

The dendritic organization of motoneurons was analyzed with the Golgi stain and a morphometric method in the immature and adult human spinal cord. Each motoneuronal column was found to be characterized by a specific orientation of dendritic trees and by a distinct pattern of dendritic bundling. Ventromedial motoneurons have a pyramidal dendritic tree with numerous, short longitudinal branches and elongated dorsal branches. The latter form thick bundles oriented toward the ventral gray commissure. Longitudinal dendrites form a narrow-meshed dendritic plexus, containing abundant microbundles. Motoneurons of the ventromedial column have fewer primary dendrites and a lower ramification index than other motoneurons. Central motoneurons are predominantly oriented longitudinally. The meshes of the rostrocaudal dendritic plexus are looser and the microbundles are finer. Most transverse dendrites run laterally and participate in dendritic bundles which penetrate into the ventrolateral funiculus. The rostrocaudal dendritic domain of ventrolateral motoneurons is the largest dendritic domain of all spinal neurons. The longitudinal dendritic network contains fine microbundles and appears wide-meshed. Transverse dendrites form lateral or medial dendritic bundles depending upon the position of their perikaryon. Dorsolateral motoneurons differ from other motoneurons by their multipolar organization with a slight preponderance of dorsoventral dendritic spread. Rudimentary lateral dendrite bundles are restricted to marginal neurons. The longitudinal plexuses of motoneuronal dendrites and the verticotransverse dendrite bundles of the ventromedial column are well developed in the 26-28-week-old fetus. In contrast, the horizontotransverse dendrite bundles of central and ventrolateral motoneurons can only be recognized from 36 weeks on. The possible specific functions of the various types of dendrites bundles are examined and a laminar dendroarchitectonic schema of the human cord is proposed. [less ▲]

Tree-ring analysis of tropical trees is especially time-consuming for the largest trees. Because of large dimensions and irregular shapes, the tree-ring measurements are generally achieved (semi-)manually directly from wood samples. The aim of this study is to present a new approach of tree-ring measurements combining photogrammetry, image processing and GIS tools that is appropriate for very large wood samples. Disks are sawed from felled trees above buttress. Small diameters holes are drilled to the disk surface to be later used as control points. Images are taken with an off-the-shelf camera and assembled with PhotoScan in order to produce an orthoimage of the green disk surface. After drying, disks are sanded (grain 80-400) and scanned with a flatbed scanner (A3 size) at high resolution (1200-2400 dpi). The scans are then mosaicked together with Autopano into one single image. Based on the control points of the green orthoimage, the ‘dry’ image is georeferenced and rectified. Using a GIS environment, tree-rings are delimited and ring widths and/or areas measured. Disks are entirely digitalized into high resolution images (0.02-0.04mm per pixel) offering a wide range of analysis possibilities. The image-based procedure reduces cost of disk handling and transportation, facilitates data processing and transfer and, is adaptable to any type of wood samples. [less ▲]
