Inhibitor of apoptosis proteins, NAIP, cIAP1 and cIAP2 expression during macrophage differentiation and M1/M2 polarization
Monocytes and macrophages constitute the first line of defense of the immune system
against external pathogens. Macrophages have a highly plastic phenotype depending on
environmental conditions; the extremes of this phenotypic spectrum are a pro-inflammatory
defensive role (M1 phenotype) and an anti-inflammatory tissue-repair one (M2 phenotype).
The Inhibitor of Apoptosis (IAP) proteins have important roles in the regulation of several cellular
processes, including innate and adaptive immunity. In this study we have analyzed the
differential expression of the IAPs, NAIP, cIAP1 and cIAP2, during macrophage differentiation
and polarization into M1 or M2. In polarized THP-1 cells and primary human macrophages,
NAIP is abundantly expressed in M2 macrophages, while cIAP1 and cIAP2 show
an inverse pattern of expression in polarized macrophages, with elevated expression levels
of cIAP1 in M2 and cIAP2 preferentially expressed in M1. Interestingly, treatment with the
IAP antagonist SMC-LCL161, induced the upregulation of NAIP in M2, the downregulation
of cIAP1 in M1 and M2 and an induction of cIAP2 in M1 macrophages.This work was supported by Universidad

Cytoarchitecture of the dorsal lateral geniculate nucleus in the rabbit
The cytoarchitecture and morphometry of
the neurons in the a, sector of the dorsal lateral
geniculate nucleus of the rabbit have been studied. The
preparation techniques used were those of Golgi-Adams
and Klüver-Barrera. Our method was to subdivide the a,
sector into three zones (superior, media1 and inferior)
and then to cut each zone along the horizontal, transverse
and saggital planes in order to obtain precise measurements
and descriptions of the neurons whatever their
orientation.
Differences exist in both the size and distribution of
neurons in the inferior zone of the a, sector compared to
the other two
Morphological changes induced by colchicine in the chick optic cup in early stages of development. A stereological study
In this study chick embryo optic cups at HH
stage 13 of development were analyzed under normal
conditions and after inoculation with colchicine for 1, 2,
4, and 8 h. Several changes were seen after these periods
of treatment: 1) modifications of the structure, with
thicker regions in the cup and a general decrease in the
total volume according to the duration of exposure to the
drug (about 4 times less than normal, 5,035 x lo3 ym3 vs
1,334 x lo3 ym3 after 8 h of treatrnent); 2) enlargement
of the ventricular cavity and its closure, due to failure of
approximation of retina1 and pigmentary layers; 3)
failure of lens development, with delay and impairment
of pit formation and deformation of al1 structures; lens
volume was less than normal (about 4 times less, 2,148 x
103 pm3 vs 658 x lo3 pm3. after 8 h of treatment); 4) a
general segregation of the cells making up the structure,
principally in the more active proliferating zones. The
local alterations found are describe

Digitization, reconstruction and spatial analysis of the archaeological record of the Middle Paleolithic site of Jarama VI (Valdesotos, Guadalajara, Spain)
Union International des Sciences Préhistoriques et Protohistoriques. Congrès Mondial (18º. 2018. París)Jarama VI is located on the NW edge of the Guadalajara province (Castilla–La Mancha, Spain). It is a rock shelter partially filled up by sediments which were excavated between 1989 and 1994. The archaeological excavation shows a lithostratigraphic sequence formed by three Pleistocene sedimentary units (Jordá 2007) with thousands of archaeological remains of the Middle Palaeolithic (Navazo et al. 2017) with an age older than 50 ka BP (Wood et al. 2012; Kehl et al. 2013; Higham et al. 2014) and even a bone remain of Homo neanderthalensis (Lorenzo et al. 2012). These human occupations correspond to later Neanderthal populations who lived in central Iberia many years before the arrival of the first modern humans to this area (Cacho et al. 2012). During this last year we have reviewed the traditional archaeological record of the excavation (excavation diaries, inventories of materials, drawings of stratigraphic sections, planes of distribution, photographs, publications, etc.) in order to digitize it and perform a spatial and statistical analysis. To do this, we have created a database where we have included all the excavation data collected in paper until now. In addition, we have made the digital topography of the site and the territory in which it is located as well as the digital model of the terrain in 3D. All the data obtained has been integrated into a Spatial Data Infrastructure. All this has allowed us to make a digital reconstruction of the archaeological record of the site. We present here the preliminary results of these works that we have made with the authorization and the financial support of the autonomous government of the Junta de Comunidades de Castilla – La Mancha.Laboratorio de Estudios Paleolíticos, Departamento de Prehistoria y Arqueología, Universidad Nacional de Educación a Distancia, EspañaDepartment of Geodesy and Geoinformatic, University Hamburg, AlemaniaEscuela Internacional de Doctorado, Universidad Nacional de Educación a Distancia, EspañaInstituto Geológico y Minero de España, EspañaDepartamento de Ingeniería Topográfica y Cartografía, Escuela Técnica Superior en Topografía, Geodesia y Cartografía, Universidad Politécnica de Madrid, EspañaDepartamento de Estadística, Investigación Operativa y Cálculo Numérico, Universidad Nacional de Educación a Distancia, EspañaProyecto Reconstrucción digital, análisis espacial y difusión del registro arqueológico del yacimiento del Paleolítico medio de Jarama VI (Valdesotos, Guadalajara) mediante las nuevas tecnologías de la información y de la comunicación.
