Annotation description: | Fig 2; Confocal images of DAG1 distribution in the rat retina shows that DAG1 is expressed in synapses of cone cells. Literal: " In the obliquely cut sections, larger immunostaining dots were definitely recognized at higher magnifications (Figure 2C). Small dots may represent rod spherules and large ones cone pedicles. These findings were consistent with that of the dystrophin immunostaining pattern (Schmitz et al. 1993; Ueda et al. 1997). Therefore, b-DG has both synaptic and nonsynaptic localization." Fig 6; Immunolocalization of DAG1 in the cone cell membrane of the flat synapse. Literal: "Cone cells have two synapses, an invaginated synapse and a flat synapse (Figure 6). Invaginated synapses have horizontal cell processes and synaptic ribbons, but flat synapses have neither. Cone cell membranes facing the bipolar cell processes showed high electron density at both synapses as well as at the rod cell membrane. The inset to Figure 6 shows beta-DG immunoreactivity at a flat synapse under the cone cell membrane." |
