Angiogenesis is a multi-stage process that drives the generation of new blood and lymphatic vessels from pre-existing ones. It is highly active during embryogenesis, largely inactive during adulthood but reactivated during wound healing and under a number of pathological conditions including cancer and ocular diseases. In addition to endothelial cells, which line the walls of the vessels, several other cell types (pericytes, macrophages, progenitor cells...) also contribute to angiogenesis. A number of signaling pathways are activated and very finely tune the delicate morphogenetic events that ultimately lead to the formation of stable blood proof neovessels. This book reviews recent advances in our understanding of the molecular and cellular mechanisms of angiogenesis, with a focus on how to integrate these observations into the context of developmental, post-natal and pathological neovascularization. The book was published under the auspices of the French Angiogenesis Society. Most contributors are prominent members of this Society or international researchers who have actively contributed to the Annual Meetings of the Society.
This book is a printed edition of the Special Issue "Mesothelioma Heterogeneity: Potential Mechanisms" that was published in IJMS
The vertebrate brain contains neurons and 3 classical types of glia cells, astrocytes, oligodendrocytes and microglia. Astrocytes and microglia have mainly been studied in gray matter, whereas oligodendrocytes myelinate white matter tracts. Until recently microglial effects were considered mainly during pathological conditions, but is now known that microglia plays important roles also in normal brain function. All these 3 glial cell types and their collaboration with neurons are important for learning. The concept that glia cells are important for cognitive function is not new. A glial-neuronal theory of brain function was proposed by Galambos in 1961. Hyden and Egyhazi demonstrated glial R...
Sancho Panza dans la tradition des nouvelles de Jean Paul Sartre, le mur, l'enfance d'un chef, erostrate nous propose des nouvelles, parfois inspirées de faits divers qui évoquent des personnages qui comme Icare se sont brulés les ailes à voler trop près du soleil.
