Synapses immunologiques et synapses neuronales [PDF]
médecine/sciences, 2003 Les systemes nerveux et immunitaire ont en commun de constituer dans l’organisme des reseaux complexes de cellules en interaction. Dans ces reseaux transitent en permanence d’enormes quantites d’informations, codees de facon tres differente dans les deux cas. Ces informations doivent en particulier circuler de cellule en cellule.

Adenosine A1 receptor activation mediates the developmental shift at layer 5 pyramidal cell synapses and is a determinant of mature synaptic strength [PDF]
, 2013 During the first postnatal month glutamatergic synapses between layer 5 pyramidal cells in the rodent neocortex switch from an immature state exhibiting high probability of neurotransmitter release, large unitary amplitude and synaptic depression to a ...

The Immunological Synapse [PDF]
Cancer Immunology Research, 2003 AbstractThe molecular interactions underlying regulation of the immune response take place in a nanoscale gap between T cells and antigen-presenting cells, termed the immunological synapse. If these interactions are regulated appropriately, the host is defended against a wide range of pathogens and deranged host cells.

Electrochemistry at the Synapse [PDF]
Annual Review of Analytical Chemistry, 2019 Electrochemical measurements of neurotransmitters provide insight into the dynamics of neurotransmission. In this review, we describe the development of electrochemical measurements of neurotransmitters and how they started with extrasynaptic measurements but now are pushing toward synaptic measurements.

Modeling Maintenance of Long-Term Potentiation in Clustered Synapses, Long-Term Memory Without Bistability [PDF]
, 2015 Memories are stored, at least partly, as patterns of strong synapses. Given molecular turnover, how can synapses maintain strong for the years that memories can persist?

Rapid, learning-induced inhibitory synaptogenesis in murine barrel field [PDF]
, 2010 The structure of neurons changes during development and in response to injury or alteration in sensory experience. Changes occur in the number, shape, and dimensions of dendritic spines together with their synapses. However, precise data on these changes

Connexin36 Expression in the Mammalian Retina: A Multiple-Species Comparison
Frontiers in Cellular Neuroscience, 2017 Much knowledge about interconnection of human retinal neurons is inferred from results on animal models. Likewise, there is a lack of information on human retinal electrical synapses/gap junctions (GJ).
