    • Thymic CD4 T cell selection requires attenuation of March8-mediated MHCII turnover in cortical epithelial cells through CD83 

      von Rohrscheidt, Julia; Petrozziello, Elisabetta; Nedjic, Jelena; Federle, Christine; Krzyzak, Lena; e.a. (Rockefeller University Press, 2016-08)
      Deficiency of CD83 in thymic epithelial cells (TECs) dramatically impairs thymic CD4 T cell selection. CD83 can exert cell-intrinsic and –extrinsic functions through discrete protein domains, but it remains unclear how ...
    • Thymic Selection of T-Cell Receptors as an Extreme Value Problem 

      Kardar, Mehran; Chakraborty, Arup K.; Shaknovich, Eugene I.; Kosmrlj, Andrej (American Physical Society, 2009-08)
      T lymphocytes (T cells) orchestrate adaptive immune responses upon activation. T-cell activation requires sufficiently strong binding of T-cell receptors on their surface to short peptides (p) derived from foreign proteins, ...
    • Thyroid hormone receptor beta and NCOA4 regulate terminal erythrocyte differentiation

      An effect of thyroid hormone (TH) on erythropoiesis has been known for more than a century but the molecular mechanism(s) by which TH affects red cell formation is still elusive. Here we demonstrate an essential role of ...
    • THz Dynamic Nuclear Polarization NMR

      Dynamic nuclear polarization (DNP) increases the sensitivity of nuclear magnetic resonance (NMR) spectroscopy by using high frequency microwaves to transfer the polarization of the electrons to the nuclear spins. The ...
    • THz generation using a reflective stair-step echelon 

      Ofori-Okai, Benjamin Kwasi; Sivarajah, Prasahnt; Huang, Wenqian; Nelson, Keith Adam (Optical Society of America, 2016-02)
      We present a novel method for THz generation in lithium niobate using a reflective stair-step echelon structure. The echelon produces a discretely tilted pulse front with less angular dispersion compared to a high ...
