Unfortunately, secondary exposure to the vector strengthens the risk of activation of memory T- and B-cells, immune reactivity events, and vector elimination.
Failure, from the side of macrophages, to destroy the absorbed mycobacteria causes a risk of activation and the development of tuberculosis [ 4, 10, 11].
Since in endemic areas socio-demographic characteristics alone rarely help identify women predisposed to TB infection, targeted screening should be conducted for all pregnant women at risk of activation (in particular HIV positive women).
The risk of polysynaptic activation increases with the density of ChR2 expression, and in circuits consisting of excitatory neurons with many recurrent connections.
Reducing the genotoxicity of genomic viral integration can, in first approximation, be equated with reducing the risk of oncogene activation, at least in the case of therapeutic payloads that have no known oncogenic potential, such as the globin genes.
Etanercept has been shown to have limited efficacy, with a possible increased risk of macrophage activation syndrome [ 8, 9].
The decline in autophagy with aging impairs cellular housekeeping and exposes cells to the risk of inflammasome activation.
Moreover, in these patients the older age may represent an additional risk factor for NSAID related bowel damage, thereby further increasing the risk of endothelial activation and PVT.
In the context of productive infection, this massive number of proteins confronts the host with plenty of antigens, against which the immune system is simultaneously primed or boosted, thereby raising the likelihood of priming immune cells against a crossreactive epitope and taking the risk of bystander activation.
The presence of well-known side effects, however, including metabolic alkalosis, the risk of neurohormonal activation, systemic vasoconstriction, electrolyte disturbances, impairment of renal function, and perhaps, worse clinical outcomes, may lead to arguments against an aggressive diuretic approach in these patients [ 10].
In contrast to RVs, LVs appear to integrate in the host genome throughout the transcriptional unit without preference for TSSs or promoters (Bushman et al, 2005), and are therefore associated to a lower risk of insertional activation of cellular genes by transcriptional mechanisms.
