Given the large number of perikarya and the absence of plexitis, it is possible that the mitosis occupied a perikaryon or sustentacular cell and that the affected ganglion was transitioning from giant ganglion to massive ganglion, though further studies would be required to confirm the identity and significance of the mitotically active cell.
Old PCs showed a remarkable loss of Nissl granules in the perikaryon. In addition, Nissl granules in the old PCs were weakly stained compared with those of young PCs (Figs.
We also assessed the expression and localization of mOatp1b2 in neurons via immunocytochemistry, which revealed immunopositive staining in membranes of the perikaryon as well as in neurites of cultured cells (Figure 4G).
Al induced tangles are found in the perikaryon and proximal parts of the dendrites and axon (50,51).
Axon injury leads to prominent cellular responses, including enhanced synthesis of RNA and protein in the neuronal perikaryon, and proliferation of reactive Schwann cells (70).
Respectively, cell body size (referring to soma and perikaryon) of MPOA neurons has been shown to be increased in late pregnant rats when compared to ovariectomized or diestrus rats.
In the histological sections of both the treated and control groups the large multi -polar neurons were dispersed among the neuroglial cells and were characterized by numerous processes extending in different directions from the perikaryon or the cell body (Fig.
Located within the epidermis and in the fibrous capsules surrounding the internal organs, chromatosomes consist of 2 to 12 uninuclear chromatophores, which are irregular cells constituted by a perikaryon and one or two peripherally ramified cell extensions through which the pigment granules translocate (McNamara, 1981).
PV+ immunoreactive neurons were intensely stained throughout the perikaryon and cell processes in all experimental animals.
Because this biochemical change could represent either a larger perikaryon or more neuritic extensions, we also assessed membrane protein markers in both absolute (membrane protein concentration) and relative (membrane/total protein) terms; an increase in extensions would augment membrane protein proportionally more than total protein.
