Web4 Jun 2024 · Although the c-Fos-tTA system enabled us to identify and manipulate engram cells, there was no approach to investigate their patterns of activity. When a neuron is activated, Ca 2+ flows into the soma. This neuronal activity can be translated into green fluorescence of a Ca 2+ indicator, such as GCaMP [ 17, 18 ]. To use tetracycline as a regulator of gene expression, a tetracycline-controlled transactivator (tTA) was developed. tTA was created by fusing tetR with the C-terminal domain of VP16 (virion protein 16), an essential transcriptional activation domain from HSV (herpes simplex virus).
