This process is often receptor-mediated, and ultimately results in internalization of the pathogen into a phagosome via a complex sequence of events involving receptor clustering, kinase activation, remodeling of the actin cytoskeleton and an increase of membrane traffic (see [1], [2], [3] for review).
NF-κB signalling initiated by different receptors requires the formation of proximal protein-protein interactions that are often receptor specific, but ultimately converge in the activation of the IκB kinase (IKK) complex, which mediates phosphorylation of the inhibitory IκB protein leading to its K48-polyubiquitination and degradation by the proteasome [ 20].
Lobular tumours are more often receptor positive than ductal tumours (Chu and Anderson, 2002), and it would therefore seem obvious that overall, lobular tumours should be associated with hormonal factors, but once receptor status has been taken into account, it is not clear whether any of the histological subtypes should be more or less associated with hormonal factors.
The GOLD results predicted HLA-DR4, HLA-DP2 and TCR as the most often targeted receptors by the peptide 1412.
Often cellular receptors are able to transduce intracellular survival signals and soluble secreted factors are mediators of growth/survival signals.
TAAs are often membrane receptors such as HER-2/neu oncoprotein, tumor suppressor gene proteins, cell cycle associated proteins (cyclin B1), centromere protein F (CENP-F), or onconeural antigens [ 13, 14].
True to the molecular signature of basal-like tumors [ 2, 3, 16], breast-ACC is often estrogen receptor (ER -negative and progER -negativeeptor (PR)-negandve [ 17- 20] and does not exprogesteroneneu [ 18, 20, 21].
Most often, the receptor for an intercellular messenger is a transmembrane receptor with the cell membrane as border between inter- and intracellular pathways.
The nicotinic acetylcholine receptor (nAChR) is an important therapeutic target for a wide range of pathophysiological conditions, for which rational drug designs often require receptor structures at atomic resolution.
In contrast, the length of an unbound interval depends only on how often the receptor gets hit and is thus more purely a measure of the concentration of molecules.
