Multiphoton microscopy enables live imaging of the renal glomerulus. However, repeated in vivo imaging of the same glomerulus over extended periods of time and the study of glomerular function independent of parietal epithelial and proximal tubular cell effects has not been possible so far. Here, we report a novel approach for non-invasive imaging of acapsular glomeruli transplanted into the an...
Olfactory receptor neurons extend axons into the olfactory bulb, where they face the challenge to integrate into existing circuitry. The consensus view is that in vertebrates individual receptor neurons project unbranched axons into one specific glomerulus of the olfactory bulb. We report here that, strikingly different from the generally assumed wiring principle in vertebrate olfactory systems...
A unique serotonin-immunoreactive neuron innervates every glomerulus of the contralateral antennal lobe (AL), the primary olfactory center, of the male silkmoth Bombyx mori. In order to examine the possible modulatory effects of serotonin in the AL, we utilized high-speed optical imaging with a voltage-sensitive dye combined with bath application of serotonin. We found that serotonin at 10(-4)m...
Variations in the origin of arteries in the abdomen are very common. With the invention of new operative techniques within the abdomen cavity, the anatomy of abdominal vessels has assumed a great deal of clinical importance. We report here a rare case of formation of an "arterial glomerulus" at the hilum of the right kidney by the branches of right renal artery. There were 2 renal veins; a supe...
Cystic partially differentiated nephroblastoma (CPDN) is extremely rare in adults. Only 2 cases have been documented in the English literature. Herein, we present a third case of CPDN with unique morphological and immunohistochemical features. A 45-year-old man had a multicystic right renal mass, with a maximum diameter of 3 cm on magnetic resonance imaging. Being unable to rule out malignancy,...
Glomerular podocytes are critical for the barrier function of the glomerulus in the kidney and their dysfunction causes protein leakage into the urine (proteinuria). Nephrin is a key podocyte protein, which regulates the actin cytoskeleton via tyrosine phosphorylation of its cytoplasmic domain. Here we report that two protein tyrosine phosphatases, PTP1B and PTP-PEST negatively regulate nephrin...
