BiTE antibodies are composed of two flexibly linked single-chain antibodies, one binding to CD3 molecules on T cells and the other to a surface antigen on the target cells.
This substance transmits the nerve impulse to the postsynaptic fibre by diffusing across the synaptic cleft and binding to receptor molecules on the postsynaptic membrane.
This information will be key for designing new compounds that can be used therapeutically to modulate immune responses by stimulating NKT cells, since such pharmacological lipid antigens will need to be able to compete effectively with endogenous lipids for binding to CD1d molecules on antigen presenting cells.
Together, the researchers of the studies found that the molecule, CD47, protects the leukemia stem cells from macrophages — part of a roving cellular army tasked with finding and engulfing diseased or dying cells — by binding to a molecule on the macrophage's surface.
Instead of binding Ca2+ directly, they perform this function by acting as bifunctional molecules, binding to actin on one hand, and providing specific sites for the binding of the troponin complex of regulatory proteins on the other hand [ 27- 30].
To access the central nervous system (CNS), cells must cross the blood-brain barrier by binding to adhesion molecules present on vascular endothelial cells.
In general terms, the solid-phase bioconjugation platform described here involves monofunctionalization of molecule A with a surface-bound cross-linker, release of an activated molecule A from the surface, and binding to a molecule B on another solid support at 1 1 molar ratio.
This implies that part of the increased affinity observed relies mainly on binding/rebinding, and not on simultaneous binding to different molecules of the antigen.
We refer to these reactivities as autoantibody reactivities because the antibodies were detected by their binding to self-molecules spotted on a microarray chip.
A possible explanation of a partial colocalization of ESTA-1 and E-selectin might be either ESTA-1 binding to other surface molecules on the endothelial cells or intracellular uptake following the initial cell surface binding since E-selectin undergoes internalization [34].
