Conclusion

Transcription

Neurodegenerative and mental health disorders result from changes in synaptic communication. Multifactorial events change synaptic receptors in ways that we do not completely understand. Microtransplantation of synaptic membranes provides insight

Résumé

The protocol demonstrates that by performing microtransplantation of synaptic membranes into Xenopus laevis oocytes, it is possible to record consistent and reliable responses of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid and γ-aminobutyric acid receptors.
