ANTECEDENTES: Estudiamos las características inmunopatològicas de 5 casos de necrólisis epidérmica tóxica utilizando un amplio panel de anticuerpos. OSERVACIONES: El patrón y grado del infiltrado celular inflamatorio varió dependiendo del estado de la enfermedad. La principal característica constante fue la importante implicación de la línea monocito-macrófago, incluyendo dendrocitos factor XIIIa+ HLA-DR+ y macrófagos CD68+ Mac 387+, antes y durante la necrosis epidérmica. El número de linfocitos CD4+ y CD8+ era comparativamente reducido. Ello se asociaba con un denso marcaje para el factor de necrosis tumoral alfa en la epidermis. CONCLUSIONES: Las células de estirpe monocito-macrófago superan en nùmero ampliamente a los linfocitos en las lesiones de la necrólisis epidérmica tóxica. El factor de necrosis tumoral alfa es problablemente una de las citocinas principales responsables de la necrosis. [less ▲]

The importance of epigenetic mechanisms is most clearly illustrated during early development when a totipotent cell goes through multiple cell fate transitions to form the many different cell types and tissues that constitute the embryo and the adult. The exchange of a canonical H2A histone for the 'repressive' macroH2A variant is one of the most striking epigenetic chromatin alterations that can occur at the level of the nucleosome. Here, we discuss recent data on macroH2A in zebrafish and mouse embryos, in embryonic and adult stem cells and also in nuclear reprogramming. We highlight the role of macroH2A in the establishment and maintenance of differentiated states and we discuss its still poorly recognized function in transcriptional activation. [less ▲]

One of the most striking epigenetic alterations that occurs at the level of the nucleosome is the complete exchange of the canonical H2A histones for the macroH2A variant. Here, we provide insight into the poorly recognized function of macroH2A in transcriptional activation and demonstrate its relevance in embryonic and adult stem cells. Knockdown of macroH2A1 in mouse embryonic stem (mES) cells limited their capacity to differentiate but not their self-renewal. The loss of macroH2A1 interfered with the proper activation of differentiation genes, most of which are direct target genes of macroH2A. Additionally, macroH2A1-deficient mES cells displayed incomplete inactivation of pluripotency genes and formed defective embryoid bodies. In vivo, macroH2A1-deficient teratomas contained a massive expansion of malignant, undifferentiated carcinoma tissue. In the heterogeneous culture of primary human keratinocytes, macroH2A1 levels negatively correlated with the self-renewal capacity of the pluripotent compartment. Together these results establish macroH2A1 as a critical chromatin component that regulates the delicate balance between self-renewal and differentiation of embryonic and adult stem cells. [less ▲]

Increase of erythromycin and clindamycin resistance among group B Streptococcus (GBS) have been reported worldwilde. Therefore phenotypical and molecular surveillance of macrolides and lincosamides resistance patterns in Belgium has been conducted. Antimicrobial susceptilities to erythromycin and clindamycin were determined by Etest® (EUCAST interpretive criteria) on 275 clinical isolates (N1) obtained from the Belgian surveillance for invasive GBS disease in newborns and adults during 2008 to 2011 and on 53 recto-vaginal colonization in pregnant women (N2) in 2010. Inducible and constitutive resistance to clindamycin were assessed by a double-disk diffusion test. The presence of genes encoding RNA methylases (erm) and efflux pumps (mef) was confirmed by PCR. Of the 328 GBS isolates, 109 (33,2%) were resistant to erythromycin. Among these isolates, 102 (93,6%) exhibited the MLS phenotype (resistant to erythromycin and clindamycin); the M phenotype (resistant to erythromycin and susceptible to clindamycin) was expressed by 7 (6,4%) of the isolates; one isolate presented a L phenotype (susceptible to erythromycin and resistant to clindalycin). For cMLS, the most common genotype was ermB (65%) (P <0,05) followed by ermTR (30%) and ermB+ermTR (5%). All iMLS isolates harbored an ermTR gene except 3 (2 with ermB, 1 with both ermB and ermTR); and all M phenotypes were positive for mefA/B gene. In Belgium, by year 2010, prevalence of macrolide and lincosamide resistance in GBS exceed 30%, with a predominance of MLS phenotypes (target-site modification). Resistance surveillance is mandatory to guide prophylaxis and treatment of serious GBS infections but also to identify newly acquired resistance mechanisms such as the L phenotype. [less ▲]

The tomato leafminer, Tuta absoluta (Meyrick), originates from South America, and remains one of the main tomato pests in this continent. Since its introduction to Europe in 2006, Mediterranean countries have also been exposed to this pest. Because of the endophytic habits of the larvae and ability of adults to reproduce parthenogenetically, chemicals and sexual pheromone- based control methods generate poor results. Recently, the use of biocontrol agents, such as Macrolophus pygmaeus Rambur (Heteroptera: Miridae), has been investigated as an alternative means of control, the results of which are presented in this review. Macrolophus pygmaeus is a mirid bug that is widely used to control different phytophagous insects in integrated pest management strategies through Europe. Several studies have confirmed the high predation potential of M. pygmaeus on T. absoluta under laboratory and semi-field conditions. This predator spontaneously colonizes tomato greenhouses in the southern Mediterranean countries. The use of banker plants (i.e., plants that provide a habitat to the predator) improves the colonization ability of this natural enemy. Hence, if the local population size is low, an augmentative strategy could be adopted. Predators may be released before or after the onset of pest infestation, with recommendations varying depending on natural population densities of both the pest and predator. The efficiency of M. pygmaeus has also been evaluated when used in combination with other biocontrol agents or with chemicals. This work presents an overview of different types of control strategies using M. pygmaeus against the tomato leafminer, T. absoluta. [less ▲]
