Description
Samples 1-8: Tissue-specific RNA sequencing (Illumina) using dissected ring glands isolated from TWO different time points of control (phm>w1118) third instar larvae. Time points are: light phase zt0-4 (which corresponde to 2-4 hours from second to third instar larvae molt); and dark phase zt18-22 (which corresponde to 16-20 hours from second to third instar larvae molt) Samples 9-32: Tissue-specific gene expression (RNA seq Illumina) using dissected ring glands isolated from TWO different time points of third instar larvae. Genotypes were Timeless-RNAi (phm>tim-RNAi), Period-RNAi (phm>per-RNAi), UAS-TimcDNA (phm>UAS-Tim) and UAS-TimcDNA;UAS-PercDNA (phm>UAS-TimcDNA;UAS-PercDNA). Goal was to identify circadin pathway dependent gene sets in the ring gland. Time points were 2-4 hours and 18-20 hours after L2-L3 molt. Overall design: This study comprises two parts: First, Next generation sequencing was used to determine transcriptional profiles from Drosophila ring glands at ZT0-4 versus ZT18-22 in control larvae. Encore Complete RNA-Seq IL Multiplex System 1-8 (Nugen Part No. 0312) and Encore Complete RNA-Seq IL Multiplex System 9-16 (Nugen Part No. 0313) was used for barcoding and multiplex sequencing. Library prep was based on total RNA isolated from dissected ring glands at two different time points during the third instar (the last larval stage of Drosophila development). Libraries were sequenced on a High-Seq Illumina platform. The second part examined gene expression changes in ring glands where we altered circadian signaling by genetic means. Encore Complete RNA-Seq IL Multiplex System was used to prep the cDNA library from total RNA isolated from ring glands of controls, ring gland-specific Timeless-RNAi (phm>tim-RNAi), Period-RNAi (phm>per-RNAi), UAS-Tim-cDNA (phm>UAS-Tim) and UAS-Tim-cDNA; UAS-Per-cDNA (phm>UAS-Tim-cDNA;UAS-Per-cDNA) larvae at two different time points in the day (ZT0-4 and ZT18-22) for the first three genotypes and exclusively at ZT18-22 for the last two genotypes. Each condition was measured by using two biological samples.

Description
Treatments that stimulate neuronal excitability enhance motor performance after stroke.cAMP-response-element binding protein (CREB) is a transcription factor that plays a key rolein neuronal excitability. Increasing the levels of CREB with a viral vector in a small pool ofmotor neurons enhances motor recovery after stroke, while blocking CREB signaling preventsstroke recovery. Silencing CREB-transfected neurons in the peri-infarct region with thehM4di-DREADD blocks motor recovery. Reversing this inhibition allows recovery to continue,demonstrating that it is possible to turn off and on stroke recovery by manipulating theactivity of CREB-transfected neurons. CREB transfection enhances re-mapping of injuredsomatosensory and motor circuits, and induces the formation of new connections withinthese circuits. CREB is a central molecular node in the circuit responses after stroke that leadto recovery from motor deficits.

Description
Untreated HIV-1 infection progresses through acute and asymptomatic stages to AIDS. While each of the three stages has well-known clinical, virologic and immunological characteristics, much less is known of the molecular mechanisms underlying each stage. Here we report lymphatic tissue microarray analyses revealing for the first time stage-specific patterns of gene expression during HIV-1 infection. We show that while there is a common set of key genes with altered expression throughout all stages, each stage has a unique gene-expression signature. The acute stage is most notably characterized by increased expression of hundreds of genes involved in immune activation, innate immune defenses (e.g.MDA-5, TLR-7 and -8, PKR, APOBEC3B, 3F, 3G), adaptive immunity, and in the pro-apoptotic Fas-Fas-L pathway. Yet, quite strikingly, the expression of nearly all acute-stage genes return to baseline levels in the asymptomatic stage, accompanying partial control of infection. In the AIDS stage, decreased expression of numerous genes involved in T cell signaling identifies genes contributing to T cell dysfunction. These common and stage-specific, gene-expression signatures provide new insights into the molecular mechanisms underlying the host response and the slow, natural course of HIV-1 infection.

Description
Microglia play important roles in developmental and homeostatic brain function, and influence the establishment and progression of many neurological disorders. Here, we demonstrate that renewable human iPSCs can be efficiently differentiated to microglial-like cells (iMGL) to study neurological diseases, such as Alzheimer''s disease (AD). We find that iMGLs develop in vitro similarly to microglia in vivo and whole transcriptome analysis demonstrates that they are highly similar to adult and fetal human microglia. Functional assessment of iMGLs reveal that they secrete cytokines in response to inflammatory stimuli, migrate and undergo calcium transients, and robustly phagocytose CNS substrates. We also show novel use of iMGLs to examine the effects of fibrillar Aß and brain-derived tau oligomers on AD-related gene expression and to interrogate mechanisms involved in synaptic pruning. Taken together, these findings demonstrate that iMGLs can be used in high-throughput studies of microglial function, providing important new insight into human neurological disease. Overall design: Human cells were collected and analyzed for gene expression using RNA-seq.
