PD-1 is ...Precise inhibition of autoreactivity without concomitant induction of general immunosuppression is an overarching goal that remains elusive for the treatment of autoimmune diseases. PD-1 is preferentially expressed on activated T cells that drive autoimmunity. These PD-1 T cells could serve as a target for therapeutic intervention. Here, we report the discovery of a unique PD-1 agonist antibody, GenSci120, that exhibited potent and selective T-cell inhibition in vitro and T-cell depletion activity both in vitro and in vivo. Target engagement by GenSci120 directly promoted SHP2 recruitment into the PD-1 signaling pathway but also enhanced the binding of PD-1 to its natural ligands and augmented PD-L1-induced PD-1 signaling. Moreover, GenSci120 exhibited robust efficacy in several animal models of human autoimmune disease. Thus, GenSci120, by selectively depleting PD-1 T cells and by directly (via PD-1 binding and SHP2 recruitment) or indirectly (via enhancing PD-1 and ligand interaction) stimulating PD-1 signaling, has the capability to restore immune balance in autoimmunity. In a first-in-human study in healthy adults (NCT06827457), GenSci120 demonstrated favorable safety/tolerability and pharmacokinetic profiles as well as robust pharmacodynamic effect. Together, these findings suggest the potential of GenSci120 as an innovative precision medicine for treating autoimmune diseases and support further evaluation of this investigational new drug in future clinical trials.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.

Jul 12, 2017. Major update of PDB

Major update of PDB

  • wwPDB released updated PDB data conforming to the new PDBx/mmCIF dictionary.
  • This is a major update changing the version number from 4 to 5, and with Remediation, in which all the entries are updated.
  • In this update, many items about electron microscopy experimental information are reorganized (e.g. em_software).
  • Now, EM Navigator and Yorodumi are based on the updated data.
