In contrast, weak FAK activation is observed at suboptimal R1881 concentration (1 pM), which poorly stimulates cell migration.
Using the same dataset, the pMHC surfaces can also provide information about the peptides that poorly stimulate the production of interferon-ã.
These may serve as one of the tumor escape mechanisms by which attracted immature DCs poorly stimulate T-cell antitumor response, and moreover can activate regulatory T cells which suppress specific anti-tumor immune responses.
The expression of LPS molecules that poorly stimulate TLR4 appears to hinder the generation of effective immunity against Y. pestis [31] and B. parapertussis, and may be a stealth strategy shared by other gram negative bacteria as well [32], [33], [34], [35].
Indeed, the respective mutants poorly stimulate polymerase δ, although loading and sliding are not affected (Fukuda et al, 1995; Lau et al, 2002).
Bordetella bronchiseptica and B. pertussis stimulate robust TLR4 responses that are required to control the infection, but a close relative, B. parapertussis, poorly stimulates this receptor, and TLR4 deficiency does not affect its course of infection.
Furthermore, contrary to the CD25+ Tregs, the CD25- Tregs proliferated poorly in the stimulated co-cultures with PBMCs.
On the other hand, DIET co-cultures were not stimulated by poorly conductive cotton cloth.
Greater anti-adhesive effects of the biosurfactant were observed against actively growing B. subtilis, C. glutamicum, E. coli, M. luteus and P. fluorescence cells (Table 2), whereas resting cells of these strains were poorly inhibited or even stimulated by the biosurfactant.
