Abstract:
The immunological synapse is a critical event for immune response development. The use of planar supported bilayers as surrogate antigen-presenting cells is a useful tool to study this phenomenon. Here we describe electron microscopy methods and approaches to expand our knowledge of the events taking place during the initial phases of T cell activation after antigen recognition at the nanometer scale.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Electrical Synapses
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...
