  • Western blots indicate that this synergistic interaction likely results from the Aβ1-42-induced upregulation of the BDNF pro-domain receptor p75NTR . (sdbonline.org)
  • neurons and the detection of these transmitters in the extracellular fluid in concentrations capable of activating their receptors suggest that the "classical" low molecular weight neurotransmitters previously thought to act exclusively on synapses, also participate in extrasynaptic communication. (frontiersin.org)
