Further, tgr2- and tgr3-derived lines exhibited persistent transgene reactivation after the reactivating mutation had been segregated away, meaning that BTG-silent provides a useful platform for studying heritable changes in gene expression in plants.
This could be a consequence of persistent pathogen reactivation and microbial translocation shown during chronic HIV-1 infection [26].
In view of clinical similarities between SJS and TEN, differences in the pattern of the viral loads between them were surprising and could be interpreted as indicating the possibility that these two diseases may be distinct in the pattern of persistent EBV reactivation, although they share important common pathophysiologic processes.
Although the precise etiology of age-associated chronic inflammation is not fully understood, several factors have been implicated including (i) damaged macromolecules and cells that activate the innate immune system (Dall'Olio et al., 2013); (ii) persistent or reactivation of latent viral infections (Wikby et al., 2006), and (iii) cellular senescence (Salama et al., 2014).
Whether intermittent shedding of the same type of HAdV in several subjects over time indicates low-grade persistent infection or episodic reactivation of latent infection is unclear.
Recently, it has been shown that host cell sphingolipids are required for inclusion integrity, a normal bacterial developmental cycle and reactivation of persistent infections [14].
The persistence of HHV-8 infection is the result of a delicate balance between immune control, viral latency, viral reactivation and persistent replication.
Reactivation of persistent M. tuberculosis infection in the adipose tissue might account, at least in part, for extra-pulmonary TB, which represent about 15% of the total reactivation cases [9], [10].
The genetic programs required by M. tuberculosis for establishment, maintenance, and/or reactivation from persistent infection within the host remain poorly defined, but are thought to include stress-adaptation systems such as extracytoplasmic function (ECF) sigma factors and two-component signal transduction systems.
(2014) have cast further doubt on this idea of reactivation of persistent virus.
Astronauts suffer from various infectious diseases such as respiratory and urinary tract infections and a higher susceptibility to the reactivation of persistent viruses, e.g. Epstein-Barr virus [ 1].
