Abstract:
During T cell development in the thymus, pre–T cell receptor (TCR) complexes signal CD4− CD8− (double negative [DN]) thymocytes to differentiate into CD4+ CD8+ (double positive [DP]) thymocytes, and they generate such signals without apparent ligand engagements. Although ligand-independent signaling is unusual and might be unique to the pre-TCR, it is possible that other TCR complexes such as αβ TCR or αγ TCR might also be able to signal the DN to DP transition in the absence of ligand engagement if they were expressed on DN thymocytes. Although αγ TCR complexes efficiently signal DN thymocyte

Abstract:
The site-specific V(D)J recombination reaction necessary to assemble the genes coding for immunoglobulin (Ig) and T cell receptor (TCR) variable regions is initiated by a precise double strand cut at the border of the recombination signals flanking the genes. Extensive processing of the coding ends before their ligation accounts for most of the Ig and TCR repertoire diversity. This processing includes both base additions to and loss from the coding ends. On the other hand, it has generally been thought that signal ends are not modified before they are fused, and that signal joints consist of a

Abstract:
Naïve CD4+ T cells experience weak T cell receptor (TCR) signals induced by self-peptides presented by MHC II. To investigate how these “basal” TCR signals influence responses to agonist TCR ligand stimulation, we analyzed naïve CD4+ cells expressing varying amounts of CD5, Ly6C, and Nur77-GFP, markers that reflect the strength of basal TCR signaling. Phenotypic analyses indicate that the broadest range of basal TCR signal strength can be visualized by a combination of Nur77-GFP and Ly6C. A range of basal TCR signaling is detectable even in populations that express identical TCRs. Whereas mode

Abstract:
Immature thymocytes undergo a selection process within the thymus based on their T cell antigen receptor (TCR) specificity that results either in their maturation into functionally competent, self-MHC–restricted T cells (positive selection) or their deletion (negative selection). The outcome of thymocyte selection is thought to be controlled by signals transduced by the TCR that vary in relation to the avidity of the TCR–ligand interaction. The TCR is composed of four distinct signal transducing subunits (CD3-γ, -δ, -ε, and ζ) that contain either one (CD3-γ, -δ, -ε) or three (-ζ) signaling mot

Abstract:
Exit from the endoplasmic reticulum (ER) is an important checkpoint for proper assembly of multimeric plasma membrane receptors. The six subunits of the T cell receptor (TCR; TCRα, TCRβ, CD3γ, CD3δ, CD3ε, and CD3ζ) are each endowed with ER retention/retrieval signals, and regulation of its targeting to the plasma membrane is therefore especially intriguing. We have studied the importance of the distinct ER retention signals at different stages of TCR intracellular assembly. To this end, we have characterized first the presence of ER retention signals in CD3γ. Despite the presence of multiple E

During αβ T cell development, T cell antigen receptor (TCR) engagement transduces biochemical signals through a protein-protein interaction (PPI) network that dictates dichotomous cell fate decisions. It remains unclear how signal specificity is communicated, instructing either positive selection to advance cell differentiation or death by negative selection. Early signal discrimination might occur by PPI signatures differing qualitatively (customized, unique PPI combinations for each signal), quantitatively (graded amounts of a single PPI series), or kinetically (speed of PPI pathway progress

Abstract:
Cytotoxic T lymphocytes (CTL) are major effector cells in the adaptive immune response against intracellular pathogens and cancers, killing targets with high precision. Precision is achieved through the specificity of the clonally expressed T cell receptor (TCR). TCRs recognise a specific peptide chain loaded into a major-histocompatability complex, triggering signalling, inducing the CTL to attach and kill target cells. Key stages in this attack are the initial conjugation followed by polarisation and docking of the centrosome to the junction of the two cells, the immune synapse (IS). This fo

TCR signal strength is critical for CD8+ T cell clonal expansion after antigen stimulation.

A few examples (for one-, two-, and high-dimensional signal sets) are then given to show the performance gain due to the overlap of signal constellation.

Abstract:
AbstractImmune response relies upon several intracellular signaling events. Among the protein kinases involved in these pathways, members of the protein kinase C (PKC) family are prominent molecules because they have the capacity to acutely and reversibly modulate effector protein functions, controlling both spatial distribution and dynamic properties of the signals. Different PKC isoforms are involved in distinct signaling pathways, with selective functions in a cell-specific manner.In innate system, Toll-like receptor signaling is the main molecular event triggering effector functions. Various isoforms of PKC can be common to different TLRs, while some of them are specific for a certain type of TLR. Protein kinases involvement in innate immune cells are presented within the chapter emphasizing their coordination in many aspects of immune cell function and, as important players in immune regulation.In adaptive immunity T-cell receptor and B-cell receptor signaling are the main intracellular pathways involved in seminal immune specific cellular events. Activation through TCR and BCR can have common intracellular pathways while others can be specific for the type of receptor involved or for the specific function triggered. Various PKC isoforms involvement in TCR and BCR Intracellular signaling will be presented as positive and negative regulators of the immune response events triggered in adaptive immunity.

Abstract:
Abstract Time domain reflectometry (TDR) is increasingly being utilized as a failure analysis tool in the semiconductor industry. TDR can provide fast, nondestructive analysis of packaged integrated circuits. With one measurement, TDR analysis can provide instant identification of the general region of the fail site, whether it exists in the substrate, interconnect region, or in the die. A digital sampling oscilloscope with a TDR module supplies a fast risetime voltage edge to the signal pin of interest, and then records the subsequent voltage edge reflections. The time delay between the incid

Abstract:
Fourier transform based frequency representation makes an underlying assumption of stationarity and linearity for the target signal whose spectrum is to be computed, and thus it is unable to track time varying characteristics of non-stationary signals that also widely exist in the physical world. Time-frequency representation (TFR) is a technique to reveal useful information included in the signals, and thus the TFR methods are very attractive to the scientific and engineering world. Local mean decomposition (LMD) is a TFR technique used in many fields, e.g. machinery fault diagnosis. Similar

Abstract:
Abstract To realize smart manufacturing in various machining processes, tool condition monitoring (TCM) systems are employed to detect the state of the tool in optimizing tool conditions and preventing catastrophic failures. Common types of TCM systems include part-specific methods and generic methods. However, many developed TCM systems lack flexibility and require extensive set-up. To address these issues, the proposed algorithm takes advantage of repetitive machining operations in manufacturing settings and adopts similarity analysis to realize tool condition monitoring by comparing the sig

Abstract:
Abstract Transmission line analysis is done in electrical failure analysis labs in order to find root causes that result in system level failures. After a fault is narrowed to a particular signal in a system, a Time Domain Reflectometer (TDR) can be used to analyze the physical transmission line associated with the signal. The transmission lines on smartphones often have inaccessible signal vias, few or no ground vias, probe points that are difficult to see, and short transmission lines. One solution that can alleviate these problems is to design a TDR Accessory Card. This paper discusses the
