In the accessory olfactory bulb (AOB), sensory neurons expressing a given vomeronasal receptor (VR) gene send divergent projections to many glomeruli, and second-order neurons (mitral cells) link to multiple glomeruli via branched primary dendrites. We used calcium imaging and paired somadendritic patch-clamp recording to track backpropagated action potentials (APs) in rat AOB primary dendrites...
The Oxford Classification of IgA nephropathy does not account for glomerular crescents. However, studies that reported no independent predictive role of crescents on renal outcomes excluded individuals with severe renal insufficiency. In a large IgA nephropathy cohort pooled from four retrospective studies, we addressed crescents as a predictor of renal outcomes and determined whether the fract...
Kidney aging is accompanied by characteristic changes in the glomerulus, but little is known about the effect of aging on glomerular parietal epithelial cells (PECs), nor if the characteristic glomerular changes in humans and rats also occur in very old mice. Accordingly, a descriptive analysis was undertaken in 27-mo-old C57B6 mice, considered advanced age. PEC density was significantly lower ...
Anti-glomerular basement membrane (GBM) nephritis in WKY rats is characterized by an accumulation of CD8-positive lymphocytes (CD8+ lym) and monocytes/macrophages (Mo/M psi) in the glomeruli and crescent formation. In the study presented here, the involvement of a chemokine for Mo/M psi, monocyte chemoattractant protein-1 (MCP-1), was examined in this model. An intense induction of mRNA for MCP...
The mammalian main olfactory system contains several subsystems that differ not only in the receptors they express and the glomerular targets they innervate within the main olfactory bulb (MOB), but also in the strategies they use to process odor information. The canonical main olfactory system employs a combinatorial coding strategy that represents odorant identity as a pattern of glomerular a...
Parietal podocytes are fully differentiated podocytes lining Bowman's capsule where normally only parietal epithelial cells (PECs) are found. Parietal podocytes form throughout life and are regularly observed in human biopsies, particularly in atubular glomeruli of diseased kidneys; however, the origin of parietal podocytes is unresolved. To assess the capacity of PECs to transdifferentiate int...
Antenna lobe (AL) in the Drosophila brain is composed of ~50 glomeruli. Each of the glomeruli has a stereotyped shape, position, and neuronal composition. However, manually identification of the glomeruli usually is very time consuming and demands high familiarity with the structure. In this project, we applied Principle Component Analysis method via Singular Value Decomposition to identify a s...
