Alternatives: "an ongoing growth of" or "a continual increase in".
Interestingly, a persistent expansion of effector memory CD4 T cells has been described in WG [13], suggesting that the increased proportion of CD45RClow CD4 T cells preferentially affects the effector memory compartment.
In our studies in WG patients, we observed a persistent expansion of a subset of memory CD4+ T cells, termed effector memory T cells (TEM), with a reciprocal decrease in naïve CD4+ T cells [ 11].
Thus, exposure to DNRAbs led to a persistent expansion of place fields that evolved even as DNRAbs were no longer present in the hippocampus, and the reduced information content of post-LPS place cells in DNRAb + mice could ultimately result in a depreciated spatial map.
For instance, Su and colleagues [ 33] demonstrated that the infection of NK-depleted mice with murine CMV results in an exaggerated immune response associated with more persistent expansion of cytotoxic CD8+ T cells that secrete IFN-γ, an important macrophage activator.
The powerful and persistent expansion of the carbon stock was an unintended co-benefit of forestry, which was motivated by the intention to improve timber yield.
Exposure to antenatal steroids might be taken into account to assess their possible positive effects on skin, renal, and pulmonary maturation,[5], [6], [13] thereby reducing IWL, the risk of disturbances in electrolyte levels, and the risk of persistent expansion of the ECF compartment respectively.
We provide evidence for a persistent, unbalanced expansion of Th17 cells and Th17 subsets which seems to be independent of disease activity.
In conclusion, we provide evidence for a persistent, unbalanced expansion of Th17 cells and Th17 cell subsets which is partly reversed by maintenance therapy in GPA.
The liver-specific deletion of Cul-3 causes a persistent and massive expansion of hepatic progenitor cells, which upon differentiation undergo remarkable DNA damage, thereby leading to a cellular senescence response and cell death.
The viability of the emerging state was assured by the persistent territorial expansion of the early Piast rulers.
I think it's because they're not taking a historical perspective, but when you look back 60 years, you see a persistent, relentless slowing of the expansion that this country has enjoyed.
