Example sentences for: activators
How can you use “activators” in a sentence? Here are some example sentences to help you improve your vocabulary:
Phorbol esters are often used as activators of PKC to investigate the role of the kinase in cellular functions [ 1 ] . Accumulating lines of evidence indicates that PMA plays a complex role in regulation of cellular function, including PKC-dependent [ 18 19 20 ] and PKC-independent ways [ 23 24 21 ] . In the present results, PMA inhibited slow membrane depolarization and action potentials in response to glucose stimulation (Fig.
SLC/CCL21, a CC chemokine expressed in high endothelial venules and in T cell zones of spleen and lymph nodes, strongly attracts naive T cells and DCs [ 1 2 3 4 5 6 7 8 ] . Because DCs are potent APCs that function as principal activators of T cells, the capacity to facilitate the co-localization of both DC and T cells may reverse tumor-mediated immune suppression and orchestrate effective cell-mediated immune responses [ 9 10 25 26 27 ] . In addition to its immunotherapeutic potential, SLC/CCL21 has been found to have potent angiostatic effects [ 28 ] , thus adding further support for its use in cancer therapy.
The plasminogen activators, tissue type and urokinase type, have been reported to be both deleterious in inflammation, owing to the proteolysis of tissue proteins, and beneficial because of fibrinolytic activity [ 26 ] . The presence of both increased urokinase and plasmin inhibitors in rheumatoid arthritis synovial tissue suggests a complex role for urokinase in this disease [ 27 28 29 ] that seems pertinent to our finding of urokinase-generated mactinin in the arthritis fluid samples.
A bias against short peptides with stop codons that terminate translation before the 15 residue limit is reached was observed among the lexA-peptide activators.
The selected peptide activators were strongly biased in amino acid composition compared to unselected library peptides.
