However, they might have a toxic effect when accumulating in excess quantities (Franceschi and Horner 1980).
IFNα has a potent antiviral effect and is secreted by plasmacytoid dendritic cells upon exposure to N. gonorrhoeae, accumulating in sufficient quantities so as to effectively block HIV-1 expression in primary CD4+ T cells [7].
The most common isotope of actinium is actinium-227; the others, natural and artificial, are too short-lived to accumulate in macroscopic quantity.
These compounds do not interfere with the microbe's metabolic machinery and hence can be accumulated in large quantities to maintain the equilibrium balance with the outer environment without allowing in large quantities of salt ions.
Certain plants, in addition, secrete or exude resins, sap, and other substances that accumulate in excessive quantities within the plant.
Helium does not accumulate in large quantities in the atmosphere because Earth's gravity is not sufficient to prevent its gradual escape into space.
In areas in which the deposited silt is highly mobile and accumulates in considerable quantities, it can be economically removed by a suction dredge, which pumps water mixed with silt into open hoppers.
Iso5:0 accumulated in greater quantities in superficial/outer blubber than in deep/inner blubber.
AMP accumulates in substantial quantities in shrimp, and it degrades to either IMP or adenosine (AdR) (Fujisawa and Yoshino 1985; Matsumoto 1996; Koseki et al. 2006; Koyama et al. 2008).
Seabirds are numerous and a potential source of nitrogen, but guano was never mined on Palmyra because it does not accumulate in significant quantities.
Given a role which F4-80+ and Gr-1+ cells played in the inflammatory response, we next examined whether these cells accumulated in different quantities in the lungs of mice with different rates of TB progression.
