Adeno-associated virus serotype 2 induces cell-mediated immune responses directed against multiple epitopes of the capsid protein VP1.

Adeno-associated virus serotype 2 (AAV-2) has been developed as a gene therapy vector. Antibody and cell-mediated immune responses to AAV-2 or AAV-2-transfected cells may confound the therapeutic use of such vectors in clinical practice. In one of the most detailed examinations of AAV-2 immunity in humans to date, cell-mediated and humoral immune responses to AAV-2 were characterized from a panel of healthy blood donors.

A possible role for protein synthesis, extracellular signal-regulated kinase, and brain-derived neurotrophic factor in long-term spatial memory retention in the water maze.

Hippocampal protein synthesis is dependent upon a number of different molecular and cellular mechanisms that act together to make previously labile memories more stable and resistant to disruption. Both brain-derived neurotrophic factor (BDNF) and extracellular signal-regulated kinase (ERK) are known to play an important role in protein synthesis-dependent memory consolidation, via the mitogen-activated protein-kinase (MAP-K) signaling pathway during the transcription phase of protein synthesis. The current study investigates the influence of protein synthesis inhibition (PSI) by cycloheximide on spatial learning and memory.
