Department of Cell Biology and Molecular Medicine, University of Szeged, Szeged, Hungary.

Morphological and functional characterizations of cultured microglia are essential for the improved understanding of their roles in neuronal health and disease. Although some studies (phenotype analysis, phagocytosis) can be carried out in mixed or microglia-enriched cultures, in others (gene expression) pure microglia must be used. If the use of genetically modified microglial cells is not feasible, isolation of resident microglia from nervous tissue must be carried out. Read More

Gene and Transposable Element Expression Evolution Following Recent and Past Polyploidy Events in (Poaceae).

Front Genet 2021 25;12:589160. Epub 2021 Mar 25.

UMR CNRS 6553 Ecosystèmes, Biodiversité, Evolution (ECOBIO), Université de Rennes 1, Rennes, France.

Gene expression dynamics is a key component of polyploid evolution, varying in nature, intensity, and temporal scales, most particularly in allopolyploids, where two or more sub-genomes from differentiated parental species and different repeat contents are merged. Here, we investigated transcriptome evolution at different evolutionary time scales among tetraploid, hexaploid, and neododecaploid species (Poaceae, Chloridoideae) that successively diverged in the last 6-10 my, at the origin of differential phenotypic and ecological traits. Of particular interest are the recent (19th century) hybridizations between the two hexaploids (2 = 6 = 62) and (2 = 6 = 60) that resulted in two sterile F1 hybrids: × (2 = 6 = 62) in England and × (2 = 6 = 62) in France.
