Systems, methods, and workflows for optogenetics analysis
The invention provides methods for characterizing cellular physiology by incorporating into an electrically excitable cell an optical reporter of, and an optical actuator of, electrical activity. A signal is obtained from the optical reporter in response to a stimulation of the cell. Either or both of the optical reporter and actuator may be based on genetically-encoded rhodopsins incorporated into the cell. The invention provides all optical methods that may be used instead of, or as a complement to, traditional patch clamp technologies and that can provide rapid, accurate, and flexible assays of cellular physiology.
1. A method for measuring network effects, the method comprising:
using an optical actuator of electrical activity incorporated into a first plurality of cells of one cell type;
obtaining a signal using an optical reporter of electrical activity incorporated into a second plurality of cells of another cell type; and
evaluating the signal.
2. The method of claim 1 , wherein the first plurality of cells of one cell type further comprises an optical reporter of electrical activity.
3. The method of claim 2 , wherein the second plurality of cells of one cell type further comprises an optical actuator of electrical activity.
4. The method of claim 1 , wherein the first plurality of cells comprises a first class of neurons.
5. The method of claim 1 , wherein the second plurality of cells comprises a second class of neurons.
6. The method of claim 1 , wherein the first plurality of cells comprises a first class of cardiomyocytes.
7. The method of claim 1 , wherein the second plurality of cells comprises a second class of cardiomyocytes.
8. The method of claim 1 , wherein the first plurality of cells comprises a first class of cells of iPSC's.
