Experimental life sciences have two basic foundations: concepts and tools. The Neuro-

of individual volumes and chapters in this series takes this new access technology into

Preface
ThepioneeringworkofRitaLevi-Montalcini,VictorHamburger,andStanleyCohenledto
the discovery of nerve growth factor (NGF) as the molecule involved responsible for the
trophic effects of innervated tissues during development of sympathetic and sensory neu-
rons. Laterstudies allowed theidentification ofother membersofthe neurotrophinfamily
oftrophicfactors:brain-derivedneurotrophicfactor(BDNF),neurotrophin-3(NT-3),and
neurotrophin-4/5 (NT-4/5). Neurotrophins have been shown to play important roles in
the control of proliferation, differentiation, survival, and death of neuronal and
non-neuronalcells,anddysregulationofthesemechanismshasbeenassociatedwithdiffer-
entdisorders.
TheeffectsofBDNFhavebeendescribedinthecentralnervoussystemaswellasinthe
peripheralnervoussystem.TheexpressionofBDNFisregulatedbyneuronalactivity,anda
precursor formoftheprotein(proBDNF)isfirstsynthesizedintheendoplasmicreticulum
and later transported to the Golgi apparatus. The intracellular trafficking of the precursor
and mature forms of BDNF has been studied to a large extent in hippocampal neurons,
wheretheneurotrophinisreleasedbyaCa2+-dependentmechanism,fromthepostsynaptic
region and from the axon terminal. BDNF acts through activation of presynaptic and
postsynaptic TrkB receptors, and the complex BDNF-TrkB activates different intracellular
mechanisms (Ras/Erk, Phosphoinositide 3-kinase [PI3-K]/Akt, and phospholipase C-γ
pathways), which have local regulatory roles. However, the BDNF-TrkB complexes may
alsotravelwithinthecellandregulateneuronalactivityinsubcellularcompartmentslocated
far away from the region where the neurotrophin was released. All these steps, from the
regulationofgeneexpressiontotheregulationofBDNFrelease,andthedifferentresponses
tostimulationofTrkBreceptors,arethesubjectofcurrentinvestigation.
BDNF is a key synaptic regulator, both during the synaptogenesis period and after
differentiation, acting on excitatory and inhibitory contacts. The effects of BDNF on
excitatorysynapseshavebeenlargelyinvestigatedinthehippocampus,whereitstrengthens
neuronal communication under specific conditions of activity. These forms of synaptic
plasticity in the hippocampus and in other brain regions are thought to underlie learning
andmemoryformation.Accordingly,BDNFhasbeenshowntoplayaroleincertainforms
oflearningandmemory.
BDNF also plays a role in various disorders of the nervous system, such as depression,
schizophrenia, obsessive-compulsive disorder, Alzheimer’s disease, Huntington’s disease,
Rett syndrome, Down syndrome, epilepsy, and dementia, as well as anorexia nervosa and
bulimia nervosa; neuroprotective effects of BDNF in brain ischemia were also reported.
Furthermore, BDNF-TrkB signaling was shown to contribute to oncogenesis in different
typesoftumors,butanupregulationoftheneurotrophinlevelsinthehypothalamussetsin
motion an anti-tumor immune response. Numerous ongoing studies aim at determining
how the deregulation of the expression, synthesis, intracellular trafficking, and release of
BDNF,aswellastheresponsesmediatedbyTrkBreceptors,areassociatedwithdiseasesof
the nervous system. The use of peripheral BDNF as a biomarker of disease has also been
proposed.

viii Preface
Besides the large number of existing studies on BDNF, the literature accumulating
over the last decades has often produced conflicting results. The ensuing debate indicated
that discrepancies between studies are in part accounted by differences in the methods
used in different laboratories. The peculiar molecular characteristics, the complex cellular
regulation, and the multitude of physiological effects of BDNF make its accurate analysis
prone to artifacts if not carried out with precise methodologies, a prerequisite to obtain
robustdata.
ThepresentvolumeofNeuromethodsdedicatedtoBDNFaimsatprovidinganoverview
of the methodologies currently used in the field to study the physiology of this neurotro-
phin, from the regulation of gene expression to its release and the signaling by TrkB
receptors, as well as in the characterization of the neuronal responses to BDNF and the
role of the neurotrophin in different diseases. We trust this book will help researchers to
furtherexplorethediversityofphysiologicalrolesofBDNF.Finally,wewouldliketothank
allcontributorsforsharingthedetailedprotocolsusedintheirlaboratories.
