Receptors, Synapses and Memory
Dr. Huganir’s research focuses on the molecular mechanisms that modulate the communication between neurons in the brain. This modulation is critical for complex processes in the brain, including learning, memory, and development. Disruption of these processes is also involved in several neurological and psychiatric diseases.
The Huganir laboratory studies the mechanisms that regulate synaptic transmission and synaptic plasticity. The general approach they have taken is to focus on molecular and cellular mechanisms that regulate neurotransmitter receptors. These receptors mediate the response of neurons to neurotransmitters released at synapses and are a central convergence point for transmission of signals between neurons. Modulation of the function of these receptors is a powerful and efficient way to modulate synaptic communication and synaptic plasticity. Over the years they have shown that receptor protein phosphorylation and the regulation of the synaptic targeting of receptors are dynamically regulated and regulate the efficiency of synaptic transmission. They are currently focusing their efforts on the mechanisms that underlie the regulation of the glutamate receptors, the major excitatory neurotransmitter receptors in the brain. These receptors are neurotransmitter-dependent ion channels that allow ions to pass through the neuronal cell membrane, resulting in the excitation of neuronal activity.
