A new tumor suppressor function of p21, needed at each undamaged duplication cycle, ensures the adequate execution of the DNA replication program thereby protecting the genome integrity.

A hyperpolarization-activated cation channel, counteracting membrane depolarization, delimits the excitability of receptor neurons subjected to naturally prolonged stimulation to preserve the function of neighboring receptor neurons in Drosophila gustation.

Insulin-like growth factor-1 activates the prefrontal cortex and improves the extinction of aversive memories.

A genetic analysis reveals that some olfactory sensilla of Drosophila do not require an abundant odorant binding protein and that one such protein may act in gain control.

A morphological characterization of Drosophila olfactory receptor neurons—conducted systematically at nanoscale resolution—yields an extensive morphometric dataset, identifies novel features of olfactory sensilla, and raises intriguing questions for how the size and shape of sensory neurons influence their function.

Although odorant binding proteins are widely believed to be required for transport of odorants to receptors, six types of sensilla of Drosophila respond robustly in their absence to many odor stimuli.

Biochemical, biophysical, and structural approach to determine the molecular basis of the calcium-sensitive regulation of the Gα chaperone and guanine exchange factor Ric-8A by the neuronal calcium sensor NCS-1.

Transient platelet accumulation supports oligodendrocyte progenitor cell differentiation during myelin repair, while sustained exposure to elevated platelet numbers hampers the generation of remyelinating cells.

A moth can detect plant volatiles using an odorant receptor expressing in its ovipositor, and this odorant receptor has a much higher expression level in the ovipositor than antennae.
