Th17 cell differentiation, however, requires TLR4, IL-6, and complement interactions [ 54].
For the pole test, there was no overall effect of sex or sex chromosome complement, but in pairwise comparisons, there were significant sex by sex chromosome complement interactions such that XYY males (but not females) took longer to turn and complete the test than XY.
In pairwise comparisons, there were sex by sex chromosome complement interactions such that XX took more steps than XY but only in gonadal males, and the XYY vs. XY difference was not consistently in the same direction for gonadal males and females.
It is the first detailed comparative study of the properties of these interesting systems with two complementing interactions (electrostatic and aromatic stacking).
Quantitative information, in the form of affinity constants for heparin-complement interactions, is not generally available and there are no reports of a comprehensive analysis using the same interaction method.
Mapping the mutations onto the atomic structure of BbCRASP-1 reveals that, in contrast to earlier assumption, the C-terminal mutations act indirectly on FHL-1 and factor H binding, whilst the region 1 mutations map the site of direct complement regulator interaction.
Since CR3 is important in FcγRIIIB-mediated phagocytosis in neutrophils (46), it is possible that polymorphisms which inhibit CR3 binding to complement or interaction with FcγRIIIB may exacerbate the effect of low FCGR3B CN.
These results suggest that non-electrostatic interactions could be exploited to complement electrostatic interactions in the design of nanocarriers.
