Plasma membranes, cell junctions and cuticle of the rectal chloride epithelia of the larval dragonfly Aeshna cyanea.
The cell membranes and cell junctions of the rectal chloride epithelia of the larval dragonfly Aeshna cyanea were examined in thin sections and by freeze-fracture. These epithelia function in active… Expand
Studies on microplasmodia ofPhysarum polycephalum
SummaryThe new technique of fluorescent analog cytochemistry was used to investigate the cell surface morphology (RITC-WGA staining), the organization of the microfilament system (Rh-phalloidin… Expand
Chemically induced changes in the morphology, dynamic activity and cytoskeletal organization of Physarum cell fragments.
Spherical cell fragments derived from Physarum polycephalum by caffeine-treatment were used as an experimental system to investigate the influence of 15 externally applied substances on the general… Expand
Shuttling of the autoantigen La between nucleus and cell surface after uv irradiation of human keratinocytes.

- 1 November 1984
Isolated muscle and Physarum actins were labeled with various fluorochromes and microinjected into living stages of Physarum polycephalum (caffeine-droplets, endoplasmic drops, thin-spread… Expand
Caffeine-Induced Surface Blebbing and Budding in the Acellular Slime Mold Physarum polycephalum
The mechanism of plasma membrane proliferation was studied in the acellular slime mold Physarum polycephalum with the aid of light and electron microscopical techniques. Treatment of protoplasmic… Expand
Dynamics and Function of Microfilaments in Physarumpolycephalum as Revealed by Fluorescent Analog Cytochemistry (FAC) and Electron Microscopy
Tetramethylrhodaminyl (TRITC)-phalloidin and isolated muscle or Physarum G-actin labeled with various fluorochromes were micro-injected into living stages of Physarum polycephalum (cell fragments and… Expand
Lipid transport through the enterocytes of larval Aeshna cyanea (Insecta, Odonata).
The larval enterocytes of A. cyanea absorb lipid after luminal lipolysis in morphologically invisible form by direct membrane transport, presumably molecular diffusion. The lipolytic products are… Expand
Absorption of dietary triacylglycerol by lipolysis and lipid resynthesis in the mesenteron of larvalAeshna cyanea (insecta, odonata)
SummaryVoluntary uptake of triolein, margarine, and lipid-rich natural food (Tubifex) by fasting dragonfly larvae (Aeshna cyanea) led to heavy accumulations of lipid absorption droplets in the… Expand
Function of the microfilament system in living cell fragments of Physarum polycephalum as revealed by microinjection of fluorescent analogs
SummarySmall cell fragments derived from plasmodial stages of Physarum polycephalum by treatment with caffeine were used to investigate the spatial organization and dynamics of the microfilament… Expand
