Bayesian causal inference of cell signal transduction from proteomics experiments
<p>Cell signal transduction describes how a cell senses and processes signals from the environment using networks of interacting proteins. In computational systems biology, investigators apply machine learning methods for causal inference to develop causal Bayesian network models of signal …

The Role of Dna Methylation and Hydroxymethylation In Smooth Muscle Cell Phenotypic Change During Atherogenesis
… atherogenesis, lipid deposits, inflammation, and cells accumulate within the walls of arteries, ultimately leading to a buildup of fatty plaques and occlusion of the arterial lumen. In a multifactorial disease like atherosclerosis there are complex interplays between environmental, genetic and …

Physiological and cellular characterization of a plant natriuretic peptide
… capacity to survive. Plants can use multiple signaling pathways and signals to mediate their response; for example, at least four different signal pathways have been identified for water-deficit stress (Shinozaki and Yamaguchi-Shinozaki, 1997; Xiong et al., 2002). Different forms of stress may …

Disulfide Bridging the Gap between Src and Cortactin: A New Paradigm in SH2 Domain-mediated Signaling
… tyrosine kinase that also regulates normal cell homeostasis through phosphorylation of multiple downstream substrates. Cortactin is an actin binding protein and nucleation promoting factor that promotes the formation of stable branching networks within the actin cytoskeleton. Together, these …

Modularity of signaling cycle architectures
… Phosphorylation cycles are ubiquitous in cell signal-transduction systems. Single phosphorylation cycles have been found to have insulating properties that reduce the effect of downstream loads. The analysis of these cycles is thus important in understanding their role in signaling systems …

Localization and Function of Bacterial Type III and IV Effector Proteins
Eukaryotic cell signal transduction networks are highly dynamic and complex systems largely composed of signaling enzymes with modular protein interaction domains and subcellular localization motifs. These sophisticated regulatory mechanisms are crucial to the fidelity and efficacy of information …

Analysis and Interpretation of Complex Biological Signal Transduction Networks
Cellular signaling is a complex system of biological communication that coordinates cellular activities via biochemical reactions. The passing of an extracellular signal across a cell membrane to intracellular signaling molecules is referred to as signal transduction. Signals transduced across a …

Actin Regulatory Dynamics Required for T Cell Activation: A Quantitative and Systems-Level Perspective
T cell activation occurs through interaction with an antigen-presenting cell (APC). Upon activation, signaling ensues with the coordination of dozens of diverse signaling molecules in space and time, a feature of cell signaling we call ‘spatiotemporal patterning’. We performed a systems-scale …

Cellular and Molecular Aspects Of Naïve T cell Priming for Adoptive Immunotherapy
… in the advancement of immunotherapy. Adoptive cell therapy (ACT) is a modality that aims to generate a robust tumour-directed response by the infusion of tumour specific, ex vivo expanded, autologous cells. In this thesis we examine aspects of naïve T cell culture with the aim of improving …

Modulation of CD8+ T Cell Function by Beta2-Adrenergic Receptor Signaling
… upon stimulation, which can modulate immune cell function primarily through the beta2-adrenergic receptor (ADRB2). Our previous work has demonstrated that various subsets of CD8+ T cells have differential expression of the ADRB2 transcript. The role of ADRB2 signaling on the differentiation …

Sympathetic Neural Control of Inflammation by ADRB2-Mediated IL-10 Secretion
… nervous system to communicate with immune cells through adrenergic receptors (ADR). Although, the effects of adrenergic signaling has been studied in multiple cell types, its role in modulation of innate immune cells is relatively unknown. Here, I demonstrate a novel role for the beta2-ADR …
