La survie et la prolifération des progéniteurs et précurseurs érythroïdes se trouvent sous le contrôle de l’érythropoïétine (Epo), qui est le principal régulateur de l’érythropoïèse. La différenciation érythroïde s’effectue sous la dépendance du facteur de transcription GATA-1 qui active l’expression des gènes de différenciation et de survie. La production des globules rouges est finement régulée par l’inhibition ou au contraire par l’induction de l’apoptose des progéniteurs et des précurseurs érythroïdes. La baisse du taux d’Epo circulante ou l’induction de la voie Fas aboutissent à l’activation de la caspase-3 qui entraîne la protéolyse de GATA-1, l’arrêt de maturation et l’apoptose des érythroblastes immatures. Nous avons montré qu’une activation transitoire de la caspase-3 par la voie mitochondriale est indispensable à la maturation érythroïde. Dans ce contexte, la protéine chaperonne hsp70 joue un rôle majeur en protégeant GATA-1 du clivage par la caspase-3. La différenciation terminale est caractérisée par une réduction progressive du volume cellulaire et du noyau associée à une condensation de la chromatine. Ces changements morphologiques présentent certaines similitudes avec ceux observés dans les cellules en cours d’apoptose. L’énucléation s’effectue ensuite au sein d’îlots érythroblastiques constitués d’un macrophage central étroitement associé par des molécules d’adhérence à des érythroblastes en cours de maturation. La membrane de l’érythroblaste perd progressivement son affinité pour le macrophage alors que le noyau reste fixé, ce qui permet l’énucléation et la phagocytose du noyau par le macrophage. Les réticulocytes ainsi formés vont compléter leur maturation en perdant leurs organelles et en remodelant leur membrane. Nos études suggèrent que le devenir des précurseurs érythroïdes (apoptose versus différenciation) est déterminé par le choix des cibles clivées par les caspases. Si la fonction du clivage de certaines protéines telles que la lamine B ou acinus est bien connue, l’identité et la fonction des autres cibles clivées par les caspases au cours de la maturation terminale restent à déterminer.

Clownfishes live in social group within sea anemones. They are prolific “singers” that produce a wide variety of sounds, described as “pops” and “chirps”, involved in both reproductive and agonistic interactions. Although clownfish sounds were recorded since 1930, the mechanism of sound production has remained unresolved. <br />The sounds used to describe the sonic mechanism were directed towards hetero- and conspecifics that approach their sea anemone host. Sound recordings were synchronized using a high speed video (500 fps) coupled or not with an X-ray system. These systems allowed to quantify the movements of external and internal bones during sound production. Sounds were typically accompanied by rapid (< 30 ms) head movements such as elevation of the skull, lowering of the hyoid bar and the anterior part of the branchial basket, retraction of the pectoral girdle, and finally closing of the mouth. Synchronization of sound pulses with X-ray images indicates that sound is produced when the hyoid apparatus is completely lowered and the mouth closed by a previously unknown mechanism. <br />Dissections of freshly dead specimens reveal an unusual ligament responsible for the rapid mouth closing. This ligament joins the hyoid bar to the internal part of the mandible. Acting as a cord, it forces the mandible to turn around its articulation during the lowering of the anterior part of the branchial basket, forcing the mouth to close. Sounds result from the collision of the jaw teeth, transferring energy to the jaws that are presumably the sound radiator. [less ▲]

Biologically speaking, Sendai virus (SeV), the murine parainfluenza virus type 1, is perceived as a common respiratory pathogen that is endemic in many rodent colonies throughout the world. Currently it is believed that SeV is the leading cause of pneumonia in mice and together with the mouse hepatitis viruses, is the most prevalent and important of the naturally occurring infections of mice. The scientific community also considers SeV as the archetype organism of the Paramyxoviridae family because most of the basic biochemical, molecular and biologic properties of the whole family were derived from its own characteristics. Recently, scientific interest for this old pathogen has re-emerged, this time because of its potential value as a vector for gene transfer. This review aimed at drawing an exhaustive picture of this multifaceted pathogen. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]
