HCN kanalları ve bunların yardımcı alt birimi arasındaki etkileşim Majör Depresif Bozukluk bir tedavi hedefi olarak tespit edilmiştir. Burada, bu protein-protein etkileşimi, küçük molekül inhibitörleri belirlemek için bir floresan polarizasyon tabanlı bir yöntem sunulmuştur.

Bu prosedürün genel amacı, TRIP8b ve HCN kanalları arasındaki etkileşimi bozabilen küçük molekülleri tanımlamaktır. Bu yöntem, depresyon için yeni tedavilere dönüştürülebilecek aday molekülleri tanımlar. Bu tekniğin ana avantajı, yüksek verimli bir şekilde tamamlanabilmesidir.

Bu tekniğin, majör depresif bozukluk için yeni bir tedavinin geliştirilmesi için etkileri vardır, çünkü laboratuvarımız TRIP8b'nin HCN'ye bağlanmasının bozulmasının terapötik fayda sağlayabileceğini göstermiştir. Bu yöntem depresyon göz önünde bulundurularak geliştirilmiş olsa da, TRIP8b ve HCN arasındaki etkileşimi bozmak, kronik ağrı gibi diğer bozukluklarda terapötik fayda sağlayabilir. Bu protokolün görsel gösterimi önemlidir, çünkü Northwestern Üniversitesi'nin yüksek verimli analiz laboratuvarı gibi açık tesislerde temel ve translasyonel araştırmaları ilerletmek için otomatik yüksek verimli araçların kullanılmasının faydalarını göstermektedir.
