Where is reactivation after a long latency?

Tuberculosis: latency and reactivation.

Epigenetic Control of Cytomegalovirus Latency and Reactivation

Cytomegalovirus (CMV) gene expression is repressed in latency due to heterochromatinization of viral genomes. In murine CMV (MCMV) latently infected mice, viral genomes are bound to histones with heterochromatic modifications, to enzymes that mediate these modifications, and to adaptor proteins that may recruit co-repressor complexes. Kinetic analyses of repressor binding show that these repres...

Gamma interferon blocks gammaherpesvirus reactivation from latency.

Establishment of latent infection and reactivation from latency are critical aspects of herpesvirus infection and pathogenesis. Interfering with either of these steps in the herpesvirus life cycle may offer a novel strategy for controlling herpesvirus infection and associated disease pathogenesis. Prior studies show that mice deficient in gamma interferon (IFN-gamma) or the IFN-gamma receptor h...

The murine gammaherpesvirus 68 v-cyclin is a critical regulator of reactivation from latency.

Gamma-2 herpesviruses encode a homolog of mammalian D-type cyclins. The v-cyclin encoded by murine gammaherpesvirus 68 (gammaHV68) induces cell cycle progression and is an oncogene (L. F. van Dyk, J. L. Hess, J. D. Katz, M. Jacoby, S. H. Speck, and H. W. Virgin IV, J. Virol. 73:5110-5122, 1999). However, the role of the pro-proliferative v-cyclins in gamma-2 herpesvirus pathogenesis is not know...

The trigeminal ganglion is a location for equine herpesvirus 1 latency and reactivation in the horse.

Four specific pathogen-free ponies were infected intranasally with equine herpesvirus 1 (EHV-1) and two were similarly infected with an EHV-1 thymidine kinase deletion mutant. The primary infections were characterized by a transient fever accompanied by virus shedding into nasal mucus and viraemia. No virus was detected in clinical specimens after 15 days post-infection. Two months later a reac...
