Article Synopsis
- Transplanting neural precursor cells (NPCs) from one mouse strain into JHMV-infected mice leads to quick rejection, with T cells playing a significant role in this process.
- The study identifies that the NKG2D receptor on natural killer (NK) cells is crucial for the rejection of NPCs that express a specific ligand, RAE-1, particularly when they are not fully developed (undifferentiated).
- Findings show that blocking the NKG2D receptor increases the survival of transplanted NPCs, and those NPCs that do not express RAE-1 survive better, indicating the importance of the NKG2D/RAE-1 interaction in the rejection mechanism.
The Effect of H-bonding and Proton Transfer on the Voltammetry of 2,3,5,6-Tetramethyl-p-phenylenediamine in Acetonitrile. An Unexpectedly Complex Mechanism for a Simple Redox Couple.

The voltammetry of 2,3,5,6-tetramethyl-p-phenylenediamine, HPD, has been studied and compared to that of its isomer N,N,N'N'-tetramethyl-p-phenylenediamine, MePD. Both undergo two reversible electron transfer processes in acetonitrile that nominally correspond to 1e- oxidation to the radical cations, MePD and HPD, and a second 1e- oxidation at more positive potentials to the quinonediimine dications, MePD and HPD. While the voltammetry of MePD agrees with this simple mechanism, that of HPD does not.
