Microglia are not necessary for maintenance of blood-brain barrier properties in health, but PLX5622 alters brain endothelial cholesterol metabolism (Brain Endo SC Seq)

Project description:Microglia are resident immune cells of the central nervous system, yet their functions far exceed those related to immunology. From pruning neural synapses during development to preventing excessive neural activity throughout life, microglia are intimately involved in the brain’s most basic processes. Studies have reported a close interaction between microglia and endothelial cells, as well as both helpful and harmful roles for microglia at the blood-brain barrier (BBB) in the context of disease. However, much less work has been done to understand microglia-endothelial cell interactions in the healthy brain. Here, we aim to determine the role of microglia at the healthy BBB. We used the colony-stimulating factor 1 receptor (CSF1R) inhibitor PLX5622 to deplete microglia and analyzed BBB ultrastructure, permeability, and transcriptome. Interestingly, we found that, despite their direct contact with endothelial cells, microglia are not necessary for maintenance of BBB structure, function, or gene expression in the healthy brain. However, we found that PLX5622 treatment alters brain endothelial cholesterol metabolism, and this effect was independent from microglial depletion, suggesting PLX5622 has off-target effects on brain vasculature.

Seasonal changes of gene expression of whole brain in Medaka fish (Oryzias latipes) SC

Project description:To examine the seasonal transcriptional landscape of medaka brain, we compared the gene expression of whole brain under SC (short-day and cool temperature conditions: 10 h light/14 h dark and 10 °C) and LW (long-day and warm temperature conditions: 14 h light/10 h dark and 26 °C) conditions.

Alexandraki-S.cerevisiae-WT SC BCS BPS

Project description:Reference experiment of wild type Saccharomyces cerevisiae cells of the BJ5457 background. Cells were grown in synthetic complete medium (SC) with the addition of the necessary aminoacids and factors (leucine, uracil, histidine, tryptophane) and harvested in exponential phase (OD=0.7-1). Cells were grown in the presence of BCS and BPS chelators. <br>

Melanoma Brain Metastasis Atlas [single-cell/nuclei RNA-sequencing (sc/snRNA-seq)]

Project description:We performed single-cell/nuclei RNA-sequencing (sc/snRNA-seq) of 22 treatment-naïve melanoma brain metastases (MBM; 5 samples using scRNA-seq and 17 snRNA-seq) from 21 patients and 10 treatment-naïve extracranial (peripheral) metastases (MPM; all snRNA-seq) from 10 patients . In total, we recovered 145,555 cell transcriptomes in 32 samples including 73,369 cells from MBM and 72,186 from MPM.
