Synapse Formation: Let's Stick Together
Synapse formation requires the precise alignment and attachment of presynaptic and postsynaptic cells. Homophilic cell adhesion molecules have now been found to have a role in these processes on both sides of the synaptic cleft.
متن کاملMigrating Brain Cells Stick Together
Slime molds provide a textbook example of self-organization. They live as single cells until food becomes scarce. Then, they broadcast chemical signals that trigger their mass assembly into a fruiting body, with some cells forming a stalk and others turning into spores that cast about in the winds to spread far and wide. Neurons in the developing brain complete their own self-organized waltz, c...
متن کاملSir3 helps telomeres stick together
Mutant phagosomes bite off more than they can chew A kbar et al. reveal that the fl y homologue of a gene mutated in human disease encodes a protein required for phagosome matura-tion and digestion of pathogens. The HOPS complex is a multi-subunit tethering factor that regulates vacuole fusion in budding yeast. Metazoans express two versions of the HOPS subunits Vps16p and Vps33p. Vps16A and Vp...
متن کاملWIMPs Are Stronger When They Stick Together
Weakly interacting massive particles (WIMPs) remain the strongest candidates for the dark matter in the Universe. If WIMPs are the dark matter, they will form galactic halos according to the hierarchical clustering observed in N-body simulations. Cold dark matter (CDM) simulations show that large dark matter structures such as galactic and cluster halos are formed by the merging of many smaller...
متن کاملHeterometallic rings made from chromium stick together easily.
The idea that coordination complexes could be used in quantum information processing (QIP) was introduced by Leuenberger and Loss, and later developed by them and others. Our contribution has been to look at the S= =2 ground state {Cr7Ni} anti-ferromagnetically coupled rings, [4,5] including measuring spin coherence times. For QIP to work there is a need to link such rings into more sophisticat...
