Feminization of the Blood Brain Barrier changes the brain transcriptome of Drosophila melanogaster males

Project description:Beyond its crucial role as a tight barrier to protect the nervous system, the Blood Brain Barrier (BBB) is increasingly being recognized for its physiological processes that affect brain function and behavior. In Drosophila melanogaster, the BBB expresses sex-specific transcripts, and a change in the sexual identity of adult BBB cells results in a significant reduction of male courtship behavior. The molecular nature of this BBB/brain interaction is unknown. Here we feminize BBB cells by targeted expression of the Drosophila female specific master regulator TraF in otherwise normal males. We examined the effect on RNA expression in dissected brains by RNA sequencing. We find that 284 transcripts change in comparison to normal males. Transcripts representing cell signaling processes and synaptic communication are enriched, as are hormonal mediators. These transcripts are candidates for the sex-specific interaction between the BBB and the brain circuits that regulate behavior.

BBBomics - Human Blood Brain Barrier Transcriptomics Hub [RNA-seq]

Project description:Functional and structural dysfunction of the blood brain barrier (BBB) leads to severe alterations in brain physiology and is believed to trigger neurodegeneration. To investigate the molecular mechanisms driving the BBB dysfunction, very few human BBB cell culture models are available; of which, the human microvascular endothelial cell line (hCMEC/D3) is the most widely used. Thus far, array-based approaches or targeted seqeuncing based approaches have been employed to characterize the gene expression of the hCMEC/D3 model. However,The goal of this study is to perform deep transcriptomic sequencing of the BBB cell line and obtain features like gene expression, expressed single nucleotide variants, alternate splice forms, circular RNAs, long non-coding RNAs and micro RNAs. We have developed blood brain barriers transcriptomics landscape using RNA sequencing and micro RNA seqeuncing data obtained from replicates of hCMEC/D3 BBB cell line.
