Neurotransmitter release from presynaptic nerve terminals is regulated by soluble NSF attachment protein receptor (SNARE) complex-mediated synaptic vesicle fusion. Tomosyn inhibits SNARE complex formation and neurotransmitter release by sequestering syntaxin-1 through its C-terminal vesicle-associated membrane protein (VAMP)-like domain (VLD). However, in(More)
Myeloid dendritic cells (mDCs) recognize and respond to polyI:C, an analog of dsRNA, by endosomal Toll-like receptor (TLR) 3 and cytoplasmic receptors. Natural killer (NK) cells are activated in vivo by the administration of polyI:C to mice and in vivo are reciprocally activated by mDCs, although the molecular mechanisms are as yet undetermined. Here, we(More)
Synaptic scaffolding molecule (S-SCAM) interacts with a wide variety of molecules at excitatory and inhibitory synapses. It comprises three alternative splicing variants, S-SCAMalpha, -beta, and -gamma. We generated mutant mice lacking specifically S-SCAMalpha. S-SCAMalpha-deficient mice breathe and feed normally but die within 24 h after birth. Primary(More)
