      • TLR8 in the Developing Mouse Nervous System

        A Toll-like receptor signaling through a noncanonical pathway negatively regulates neurite growth and stimulates neuronal apoptosis.

      • Removing Proinflammatory Signals

        Macrophage engulfment of late apoptotic immune cells that have abundant CCR5, which binds proinflammatory chemokines, contributes to resolution of inflammation.

      • Deadly Redundancy

        Mouse cells have an alternative cell death pathway mediated by permeabilization of lysosomes.

      • Fungal Gib2, an Atypical Gβ Subunit

        A fungal RACK1 homolog, Gib2, with a seven-bladed β propeller structure serves as the β subunit in G protein signaling.

      • Herding Olfactory Axons

        Guidance of developing olfactory neurons depends on cAMP to signal an approximate position at which the axons will find their target glomeruli.

      • Formation of Ion Channel Complexes

        Large-conductance Ca2+- and voltage-activated K channels (BKCa channels) from brain can be found forming complexes with all three major voltage-gated Ca2+ channels.

      • Alzheimer’s Enzyme and Myelination

        An enzyme that cleaves the precursor of the amyloid peptide that accumulates in Alzheimer's disease unexpectedly also regulates the myelination of nerves.

      • Ring Around the Spindle Checkpoint

        Centrosomal proteins are important for cell cycle progression, but their role does not require their presence in the centrosome itself.
