    Notizen: Summary: Teleosts (bony fish) are thought to primarily or exclusively possess a single, structural form of immunoglobulin (Ig), a tetrameric IgM. However, in species wherein intact Ig has been electrophoretically analyzed under denaturing, non-reducing conditions, a significato degree of structural diversity has been revealed. This IgM molecule appears to be assembled with great latitude in the degree of disulfide crosslinking between monomeric or hallmark subunits composing the complete IgM molecule. This heterogeneity in the basic structure (herein referred to as redox forms) is not due to isotopic differences as each B cell produces this heterogeneity within its immunoglobulin product. Additionally, in the case of the catfish, a single fish/mouse chimeric Ig H gene is capable of producing IgM with a comparable amount of structural heterogeneity within the mouse cell. Thus, the piscine B lymphocyte routinely assembles a variety of redox forms from one IgM H chain. This has both profound biosynthetic implications for macromolecular assembly processes as well as intriguing possibilities for the generation of teleost Ig functional diversity.

    Notizen: Abstract: Suppression of protein synthesis in the brain following an ischemic insult has been thought to occur because of inhibition of translation initiation. All eukaryotic mRNAs, with the exception of heat-shock transcripts, require the activity of eukaryotic initiation factor (eIF) 4E for formation of the translation initiation complex, and eIF-4E availability is rate-limiting. The response of brain eIF-4E concentration and phosphorylation following decapitation ischemia was studied in rat brain homogenates after electrophoresis and western blotting with antibodies against eIF-4E and phosphoserine, respectively. There was no change in level of eIF-4E after 5 min of ischemia (p = 0.82 vs. time 0), but it had decreased 32 (p = 0.01) and 57% (p = 0.006) after 10 and 20 min of ischemia, respectively. There was no loss of serine phosphorylation on eIF-4E beyond signal loss observed due to degradation of the protein itself (p = 0.31). In vitro exposure of eIF-4E to activated μ-calpain resulted in a 50% loss in 10 min of eIF-4E on western blots. If active eIF-4E is required for translation of its own mRNA, degradation of this protein during ischemia, possibly by activated μ-calpain, could be a direct mechanism of irreversible neuronal injury, and the rate of proteolysis of eIF-4E could place an upper time limit on the maximal duration of global brain ischemia compatible with neurologic recovery.
