abstract = {The homodimer NGF (nerve growth factor) exerts its neuronal
activity upon binding to either or both distinct
transmembrane receptors TrkA and $p75^{NTR}$. Functionally
relevant interactions between NGF and these receptors have
been proposed, on the basis of binding and signaling
experiments. Namely, a ternary $TrkA/NGF/p75^{NTR}$ complex
is assumed to be crucial for the formation of the so-called
high-affinity NGF binding sites. However, the existence, on
the cell surface, of direct extracellular interactions is
still a matter of controversy. Here, supported by a
small-angle x-ray scattering solution study of human NGF, we
propose that it is the oligomerization state of the secreted
NGF that may drive the formation of the ternary
heterocomplex. Our data demonstrate the occurrence in
solution of a concentration-dependent distribution of dimers
and dimer of dimers. A head-to-head molecular assembly
configuration of the NGF dimer of dimers has been validated.
Overall, these findings prompted us to suggest a new, to our
knowledge, model for the transient ternary heterocomplex,
i.e., a $TrkA/NGF/p75^{NTR}$ ligand/receptors molecular
assembly with a (2:4:2) stoichiometry. This model would
neatly solve the problem posed by the unconventional
orientation of $p75^{NTR}$ with respect to TrkA, as being
found in the crystal structures of the TrkA/NGF and
$p75^{NTR}/NGF$ complexes.},
