Signal intensity and feedback regulation are known to be major factors in the signaling events stemming from the T-cell receptor (TCR) and its various coreceptors, but the exact nature of these relationships remains in question. We present a mathematical model of the complex signaling network involved in T-cell activation with cross-talk between the Erk,(More)
The T cell signaling protein Themis1 is essential for the positive and negative selection of thymocytes in the thymus. Although the developmental defect that results from the loss of Themis1 suggests that it enhances T cell receptor (TCR) signaling, Themis1 also recruits Src homology 2 domain-containing phosphatase-1 (SHP-1) to the vicinity of TCR signaling(More)
Computational approaches to tune the activation of intracellular signal transduction pathways both predictably and selectively will enable researchers to explore and interrogate cell biology with unprecedented precision. Techniques to control complex nonlinear systems typically involve the application of control theory to a descriptive mathematical model.(More)
DNA binding of two hybrid ligands composed of an alkylating pyrrolo[2,1-c][1,4]benzodiazepine (PBD) moiety tethered to either a naphthalimide or a phenyl benzimidazole chromophore was studied by DNA melting experiments, UV and fluorescence titrations, CD spectroscopy and isothermal titration calorimetry (ITC). Binding of both hybrids results in a remarkable(More)
