Anterograde transsynaptic tracing in the murine somatosensory system using Pseudorabies virus (PrV): a "live-cell"-tracing tool for analysis of identified neurons in vitro.
The Pseudorabies virus (PrV) strain Bartha is widely used as a tool for retrograde transneuronal tracing in mammals. Traced neurons can be identified in cell culture allowing the analysis of their physiological features ("live-cell"-tracing). ⋯ Following intranasal application in mice, labelled trigeminal and brainstem neurons could be identified in vitro. Detailed electrophysiological analysis indicated that viral infection did not affect neuronal properties, making PrV-Kaplan eligible for functional analysis of identified neurons within somatosensory systems.
