Abstract
: Long-term potentiation (LTP) is one of the most important topics in neuroscience. It refers to a long-lasting increase in synaptic efficacy and is considered as a molecular and cellular mechanism of learning and memory. Neurotrophins play essential roles in different processes in the central nervous system (CNS), such as synaptogenesis, survival of specific populations of neurons, and neuroplasticity. Some evidence suggests that neurotrophins also participate in the synaptic plasticity related to learning and memory formation. Brain-derived neurotrophic factor (BDNF) is an important neurotrophic factor that is extensively expressed in the hippocampus and cerebral cortex, where it promotes neuroprotection, increases synaptogenesis and neurotransmission, and mediates synapse formation and synaptic plasticity. In this review, we first focused on the research investigating the effects of BDNF on synaptic plasticity and LTP induction and then reviewed the neuronal signaling molecules employed by BDNF to promote its effects on these processes.
