KCNK2 was previously shown to regulate immune-cell trafficking into the central nervous system (CNS). Kcnk2-/- mice demonstrated a more severe disease course in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis, due to an increased immune-cell migration into the CNS. An upregulation of the cellular adhesion molecules ICAM1 and VCAM1 on brain endothelial cells in K...

A qualitative and quantitative electron microscopic study was performed on rat adipocytes during stimulation of lipolysis by various agents. Scanning electron microscopy of control cells revealed a spherical cell with a textured glycocalyx surface exhibiting small irregular projections. Globular surface evaginations or protrusions measuring 8-18 muM in diameter were seen on cell hemispheres, an...

Communication among cells by means of the exchange of signaling cues is important for tissue and organ development. Recent reports indicate that one way that signaling cues can be delivered is by movement along cellular protrusions interconnecting cells. Here, by using confocal laser scanning microscopy and three-dimensional rendering, we describe in Drosophila melanogaster wing imaginal discs ...

objectives: geographic tongue or migratory glossitis is an inflammatory disorder with unknown etiology. considering the accompanied burning pain, taste dysfunction, and lack of definite cure, it is important to treat this condition symptomatically. the objective of the current study was to compare the efficacy of a combination of 0.05% retinoic acid and 0.1% triamcinolone acetonide with that of...

Zooplankton of the Laurentian Great Lakes developed hernial protrusions whose gross appearance matches those on zooplankton described elsewhere in the world. We have carried out a histologic and cytologic analysis of the protrusions and found that they are composed of apparently degenerating or necrotic tissue(s) that has been expressed from the organism through the process of herniation. At th...

The small GTPase RhoD regulates actin cytoskeleton to collapse actin stress fibers and focal adhesions, resulting in suppression of cell migration and cytokinesis. It also induces alignment of early endosomes along actin filaments and reduces their motility. We show here that a constitutively activated RhoD generated two types of actin-containing thin peripheral cellular protrusions distinct fr...

Dysbindin is a schizophrenia susceptibility gene required for the development of dendritic spines. The expression of dysbindin proteins is decreased in the brains of schizophrenia patients, and neurons in mice carrying a deletion in the dysbindin gene have fewer dendritic spines. Hence, dysbindin might contribute to the spine pathology of schizophrenia, which manifests as a decrease in the numb...
