    Scientific background

    Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin family of growth factors which includes nerve growth factor (NGF), neurotrophin-3 (NT-3) and neurotrophin-4/5 (NT-4/5).

    All neurotrophins are synthesized as preproneurotrophin precursors that are subsequently processed within the intracellular transport pathway to yield proneurotrophins that are further processed to generate the mature form. The mature form of BDNF is a non-covalent stable homodimer that can be secreted in both constitutive and regulated pathways.

    BDNF conveys its activity by binding to two classes of receptors, a member of the Trk receptor tyrosine kinase family (TrkB) and the pan-neurotrophin receptor p75NTR. Binding of BDNF to the TrkB receptor triggers ligand-induced dimerization and autophosphorylation of tyrosine residues. This activates various signaling cascades such the MAPK, PI3K and PLCγ pathways that are involved in cell growth, survival and differentiation of neurons in the central and peripheral nervous system.  Interestingly, recent evidence suggests that BDNF may influence target cell function via ion channel modulation. Ion channel activity in the target cells can be modulated by a TrkB-mediated mechanism that has not yet been determined. BDNF is able to block both KV1.3 and AMPA-subtype glutamate ion channel currents in sensory neurons, while it can induce activation of the TRPC3 cation channel in neurons and of the NaV1.9 Na+ channel in hippocampal neurons. These newly recognized BDNF actions underlie its “rapid” neuronal functions that include changes in neuronal  excitability, plasticity and synaptic transmission.

    Last update: 05/11/2018

    Alomone Labs is pleased to offer a highly specific antibody directed against an epitope of human brain-derived neurotrophic factor. Anti-BDNF Antibody (#ANT-010) can be used in western blot, immunocytochemistry, and immunohistochemistry applications. It has been designed to recognize BDNF from rat, human, and mouse samples. The antibody is specific for BDNF; it does not crossreact with NGF, NT-3 or NT-4.
