Co-Stimulation–Induced AP-1 Activity is Required for Chromatin Opening During T Cell Activation [RNA-seq]

ABSTRACT: Activation of T cells is dependent on organized and timely opening and closing of chromatin. We perform ATAC-seq (subseries 1), ChIP-seq (subseries 2), and RNA-seq (subseries 3) at 5, 24, and 60 h of T cell activation with anti-CD3 and -CD28 antibodies in human primary naïve CD4 T cells. We report that chromatin opening at early time points is established by AP-1 transcription factor and associated with transcriptional enhancer identified as risk loci for multiple immune diseases in human naïve CD4 T cells.

Stomatal opening under high temperatures is controlled by the OST1-regulated TOT3–AHA1 module

Project description:Plants continuously respond to changing environmental conditions to prevent damage and maintain optimal performance. To regulate gas exchange with the environment and to control abiotic stress relief, plants have pores in their leaf epidermis, called stomata. Multiple environmental signals affect the opening and closing of these stomata. High temperatures promote stomatal opening (to cool down), and drought induces stomatal closing (to prevent water loss). Coinciding stress conditions may evoke conflicting stomatal responses, but the cellular mechanisms to resolve these conflicts are unknown. Here we demonstrate that the high-temperature-associated kinase TARGET OF TEMPERATURE 3 directly controls the activity of plasma membrane H+-ATPases to induce stomatal opening. OPEN STOMATA 1, which regulates stomatal closure to prevent water loss during drought stress, directly inactivates TARGET OF TEMPERATURE 3 through phosphorylation. Taken together, this signalling axis harmonizes stomatal opening and closing under high temperatures and drought. In the context of global climate change, understanding how different stress signals converge on stomatal regulation allows the development of climate-change-ready crops.

T cell-specific deletion of TRAIL-receptor reveals a critical role for pathologic T cell activation and inflammation in experimental autoimmune encephalomyelitis

Project description:We isolated CD4 T cells from EAE mice with or without TRAIL treatment and analyzed by RNA-seq. We also activated naïve CD4 T cells by anti-CD3/CD28 antibodies in the presence or absence of TRAIL and subsequently analyzed using RNA-seq.

Effect of costimulation on microRNAs levels in human naïve CD4 T cells

Project description:microRNA transcriptional profiling of human naïve CD4 T cells comparing cells that saw no activation, only anti-CD3 or anti-CD3 and anti-CD28 to identify microRNAs specifically upregulated by CD28-mediated costimulation. Three conditions experiment. PBS, anti-CD3, anti-CD3 + anti-CD28 all compared to a reference sample. Biological triplicates, independently extracted and activated.

Specific transcriptional programs differentiate ICOS and CD28 co-stimulatory signals in human naïve CD4 + T cells

Project description:a global transcriptome profiling was performed by RNA-seq on naïve CD4+ T cells upon ICOS or CD28 co-stimulation and bioinformatically was revealed a set of pathways specifically associated to each costimulatory molecule.

Analysis of Th17 gene signature in the presence of CD28 costimulation in human CD4 naïve T cells

Project description:We determined differentially regulated gene expression profile in CD4 naïve T cells cultured in presence or absence of Th17 inducing cytokines (IL23+IL1β) and anti-CD28. We reported that CD28 costimulation induced Th17-suppressive gene signature.

STAT1 and STAT3 ChIP-seq for naive and effector memory (Tem) CD4 T-cells after IL-6 treatment

Project description:Naïve and activated T-cells has a different response to antigenic challenge. We examine whether a cytokine like IL-6 induces different responses through the Jak-STAT pathway to affect the functional characteristics of a given CD4 T‑cell subset. We isolated naïve and effector memory (Tem) CD4 T-cells to investigated STAT1 and STAT3 binding after 1-hour treatment with 20ng/ml IL-6 in the presence of anti-CD3/CD28.

Blue light and CO2 signals converge to regulate light-induced stomatal opening

Project description:Stomata regulate gas exchange between plants and the atmosphere by integrating opening and closing signals. Stomata open in response to low CO2 concentrations to maximize photosynthesis in the light; however, the mechanisms that coordinate photosynthesis and stomatal conductance have yet to be identified. Here, we characterize CBC1/2 [CONVERGENCE of BLUE LIGHT (BL) and CO2 1/2], two kinases that link BL, a major component of photosynthetically active radiation (PAR), and the signals from low concentrations of CO2 in guard cells. CBC1/CBC2 redundantly stimulate stomatal opening by negatively regulating S-type anion channels in response to both BL and low concentrations of CO2. CBC1/CBC2 function in the signaling pathways of phototropins and HT1 (HIGH LEAF TEMPERATURE 1). CBC1/CBC2 interacted with and were phosphorylated by HT1. We propose that CBCs regulate stomatal aperture by integrating signals from BL and CO2 and act as the convergence site for signals from PAR and low CO2.
