Optimization of stereospecific targeting technique for selective production of monoclonal antibodies against native ephrin type-A receptor 2.

High priority stereospecific targeting (SST) featuring selective production of conformation-specific monoclonal antibodies was directed against a native receptor, EphA2 (ephrin type-A receptor 2). A critical point for this technology is selection of sensitized B lymphocytes by antigen-expressing myeloma cells through their B-cell receptors (BCRs). The essential point is that antigens expressed on myeloma cells retain their original three dimensional structures and only these are recognized.

Significance of the rapid increase in GSH levels in the protective response to cadmium exposure through phosphorylated Nrf2 signaling in Jurkat T-cells.

Although cadmium (Cd) is a redox system disruptor, the systematic defensive responses to Cd-induced oxidative stress remain unclear. In this study, we initially determined that when human T-cell-derived Jurkat cells were exposed to a low concentration of Cd, the glutathione (GSH) concentration rapidly increased via the transient nuclear accumulation of the transcription factor Nrf2. Therefore, we hypothesized that this increase in the GSH levels was a significant event that occurred in response to the Cd toxicity in the Jurkat T-cells.
