FIG 1.

KLF15 and the GR are frequently found in the same TG neuron during DEX-induced reactivation from latency. Immunohistochemistry (IHC) of consecutive sections was examined for KLF15 and GR expression in TG neurons when latently infected calves were treated with DEX for 6 h to initiate reactivation from latency, as described in the Materials and Methods section. The numbers denote TG neurons that are positive for KLF15 and the GR. The letters denote GR⁺ KLF15-negative neurons. As a control, TG sections from latently infected calves were examined for GR and KLF15 expression. Since GR and KLF15 were not readily detected in TG neurons during latency, consecutive sections were not examined. These results are representative of TG sections from two different calves.
