                  Your guide to glutamatergic neuron markers


                  Glutamatergic neurons produce glutamate, which is one of the most common excitatory neurotransmitters in the central nervous system (CNS). 

                  It plays a critical role in fundamental processes, such as learning, cognition, and memory, and dysregulation of glutamatergic transmission can result in several neurological conditions.

                  There are several well-characterized glutamatergic neuron markers, which can help you identify your neuronal population.


                  • Vesicular glutamate transporters 1 and 2 (vGlut1 and vGlut2) markers
                  • Glutamate [NMDA] receptor subunits 1 and epsilon-2 (NMDAR1 and NMDAR2B) markers
                  • Glutamate biosynthesis and metabolism markers


                  You may also be interested in our human iPSC-derived glutamatergic neurons.


                  Vesicular glutamate transporters 1 and 2 (vGlut1 and vGluT2) markers


                  Vesicular glutamate transporters transport cytoplasmic glutamate into synaptic vesicles. There are three mammalian glutamate transporters, vGluT1 – VGluT3, which have partially overlapping expression patterns. ​

                  vGluT1

                  vGluT1 is expressed in neuron-rich regions of the brain and is associated with synaptic vesicle membranes.

                  NMDA receptors are ion channels that are activated by glutamate and glycine. They play an important role in many neuronal functions, including synaptic plasticity, synaptogenesis, and memory.
