Acid to remember
Antibodies against a vaccine vector render T cells more susceptible to HIV-1 infection, say Perreau et al. on page 2717. Their results may help explain the failure of a recent HIV vaccine trial. The HIV-1 vaccine used in Merck's STEP trial relied on a weakened form of a common cold virus, Adenovirus 5 (Ad5), to carry bits of HIV into the body. One worry about the Ad5 vector was that widespread ...
متن کاملA Cluster to Remember
Based on a massive transcription factor location analysis within a single cell type, in this issue Yan et al. find that the great majority of occupancies occur within dense clusters of up to 100 factors that almost invariably contain cohesins. Retention of cohesins at cluster sites during mitosis raises the possibility that they contribute to transcriptional memory during the cell cycle.
متن کاملMolecules to Remember
"Working memory" is used for the transient storage of information in the brain. In this issue of Cell, Wang et al. (2007) now reveal how a series of molecular events involving alpha2A-adrenoceptors and a class of ion channels gated by cAMP tune the responses of neural circuits that function in working memory in mammals.
متن کاملA piRNA to Remember
In this issue of Cell, Rajasethupathy et al. report a surprising role for piRNAs, previously thought to act mainly in the animal germline to silence transposons, in transcriptional regulation of plasticity-related genes in the central nervous system of the sea slug Aplysia californica. The findings expand the functions of small RNAs and have important implications for our understanding of how t...
متن کاملNotch to remember.
Some of the signaling molecules required for formation of long-term memories are involved primarily in adult brain function, but others participate in a variety of other biological processes. The Notch signaling pathway, which is important for cell fate specification and differentiation in various systems, is also active in the mature brain. Here, we review evidence from recent studies indicati...
