N-methyl-D-aspartate receptors (NMDARs) play a central role in synaptic plasticity, learning and memory, and are implicated in various neuronal disorders. We synthesized a diffusible photochromic glutamate analogue, azobenzene-triazole-glutamate (ATG), which is specific for NMDARs and functions as a photoswitchable agonist. ATG is inactive in its dark-adapted trans-isoform, but can be converted...

The steady-state levels and half-lives of CYC1 mRNAs were estimated in a series of mutant strains of Saccharomyces cerevisiae containing (i) TAA nonsense codons, (ii) ATG initiator codons, or (iii) the sequence ATA ATG ACT TAA (denoted ATG-TAA) at various positions along the CYC1 gene, which encodes iso-1-cytochrome c. These mutational alterations were made in backgrounds lacking all internal i...

The decision of stem cells to proliferate and differentiate is finely controlled. The Caenorhabditis elegans germline provides a tractable system for studying the mechanisms that control stem cell proliferation and homeostasis [1-4]. Autophagy is a conserved cellular recycling process crucial for cellular homeostasis in many different contexts [5], but its function in germline stem cell prolife...

Low-dose antithymocyte globulin (ATG) plus pegylated granulocyte colony-stimulating factor (G-CSF) preserves β-cell function for at least 12 months in type 1 diabetes. Herein, we describe metabolic and immunological parameters 24 months following treatment. Patients with established type 1 diabetes (duration 4-24 months) were randomized to ATG and pegylated G-CSF (ATG+G-CSF) (N = 17) or placebo...

BACKGROUND Antithymocyte globulin (ATG) is used as induction therapy after cardiac transplant for enhancing immunosuppression and delaying the initiation of nephrotoxic drugs. It is unknown if ATG induction is associated with decreased coronary plaque progression by intravascular ultrasound (IVUS). METHODS AND RESULTS Patients transplanted between March 2010 and December 2012 with baseline an...

BACKGROUND AND OBJECTIVES Induction therapy with IL-2 receptor antagonist (IL2-RA) is recommended as a first line agent in living donor renal transplantation (LRT). However, use of IL2-RA remains controversial in LRT with tacrolimus (TAC)/mycophenolic acid (MPA) with or without steroids. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The Organ Procurement and Transplantation Network registry w...

INTRODUCTION Sensitization is associated with worse clinical outcomes after kidney transplantation (KT), including increased incidence of delayed graft function, acute rejection (AR) and graft loss. OBJECTIVES To evaluate 1-year efficacy and safety outcomes in sensitized KT recipients receiving antithymocyte globulin (ATG) induction and compare them to non-sensitized patients. METHODS Decea...

PurposeRabbit anti-thymocyte globulin (ATG) therapy has been used for induction to allow delay of initiation calcineurin inhibitor (CNI) immediately post-heart transplant (HTx) in patients with moderate severe renal insufficiency. In our program, this approach routine serum creatinine >2.0 mg/dL. Although mode shown be effective protection, its benefit not established less insufficiency, the 1....

kaposi᾽s sarcoma (ks) can develop in 0.06% to 4.1% of kidney transplant recipients. here we describe a case of 50-year-old man who developed ks a few months after kidney transplantation . after transplantation, he had delayed graft function and was managed by anti-thymocyte globulin (atg) for five days. at the discharge, his immunosuppressive therapy was prednisolone 20 mg/day, ttacrolimus (ppr...
