It remains unclear how readiness for Ca(2+)-dependent exocytosis depends on varying degrees of SNARE complex assembly. Here we directly investigate the SNARE assembly using two-photon fluorescence lifetime imaging (FLIM) of Förster resonance energy transfer (FRET) between three pairs of neuronal

The encephalitic response to viral infection requires local chemokine production and the ensuing recruitment of immune and inflammatory leukocytes. Accordingly, chemokine receptors present themselves as plausible therapeutic targets for drugs aimed at limiting encephalitic responses. However, it remains unclear which

Factor-inhibiting hypoxia-inducible factor (HIF)-1 (FIH-1) is an asparaginyl β-hydroxylase enzyme that was initially found to hydroxylate the HIF-α, preventing its transcriptional activity and leading to adaptive responses to hypoxia. More recently, other substrates, such as neurogenic locus notch homolog (Notch)

Diabetes mellitus is associated with disturbed zinc homeostasis and down-regulation of zinc transporter 8 (ZnT8); these changes contribute to the defective biosynthesis, storage, and secretion of insulin. Previous studies have reported an improvement in diabetic status and insulin levels in

We previously reported that bone morphogenetic protein 4/drosophila mothers against decapentaplegic protein (BMP4/Smad) signalling pathway initiated primordial follicle growth and prevented oocyte apoptosis via up-regulation of Sohlh2 and receptor for kit ligand (c-kit). The mechanism underlying this process was not
