Monolayers of cancer-derived cell lines are widely used in the modelling of the gastrointestinal (GI) absorption of drugs and in oral drug development. However, they do not generally predict drug absorption in vivo. Here, we report a robotically handled system

The oxytocin receptor (OTR) and the 5-hydroxytryptamine 2A receptor (5-HTR2A) are expressed in similar brain regions modulating central pathways critical for social and cognition-related behaviors. Signaling crosstalk between their endogenous ligands, oxytocin (OT) and serotonin (5-hydroxytryptamine, 5-HT), highlights the complex

Oxytocin mediates its behavioural effects via the centrally expressed oxytocin receptor (OTR). Oxytocin signalling has been implicated in multiple disorders involving centrally regulated pathways, including obesity, autism, schizophrenia and depression. The OTR has been described to have a complex downstream
