B Cell Expansion Hinders the Stroma-Epithelium Regenerative Crosstalk During Mucosal Healing
2021
Little is known about the pro-resolution role of immune cells recruited to damaged tissue. Using an experimental model of intestinal epithelial damage and repair, we identified B cells as the dominant cell type in the healing colon. Single-cell RNA-sequencing (scRNAseq) revealed the expansion of an IFN-induced B cell subset during experimental mucosal healing which was associated with colitis severity. In line with this, B cell depletion during mucosal healing resulted in accelerated recovery upon injury, which was associated with enhanced expression of tissue remodeling genes. scRNA-seq from the epithelial and stromal compartment confirmed that lack of B cells during mucosal healing alters…
The Norway spruce genome sequence and conifer genome evolution
2013
Conifers have dominated forests for more than 200 million years and are of huge ecological and economic importance. Here we present the draft assembly of the 20-gigabase genome of Norway spruce (Picea abies), the first available for any gymnosperm. The number of well-supported genes (28,354) is similar to the >100 times smaller genome of Arabidopsis thaliana, and there is no evidence of a recent whole-genome duplication in the gymnosperm lineage. Instead, the large genome size seems to result from the slow and steady accumulation of a diverse set of long-terminal repeat transposable elements, possibly owing to the lack of an efficient elimination mechanism. Comparative sequencing of Pinu…
