The role of the inositol phosphate cascade in visual excitation of invertebrate microvillar photoreceptors
The identity of the transmitter(s) involved in visual transduction in invertebrate microvillar photoreceptors remains unresolved. In this study, the role of inositol 1,4,5-trisphosphate (IP3) was examined in Limulus ventral photoreceptors by studying the effects on the light response of heparin and neomycin, agents that inhibit the production or action of IP3. Both heparin and neomycin reduce r...

متن کاملTransduction mechanisms of vertebrate and invertebrate photoreceptors.
Vertebrate and invertebrate visual photoreceptors detect light with exquisite sensitivity and rapid kinetics. They can detect single photons and by adapting to background light respond to changes in illumination over broad ranges of intensity. This review outlines the quite different biochemical mechanisms by which vertebrate and invertebrate photoreceptors respond to light (Fig. 1). Photorecep...
متن کاملInositol phospholipid metabolism and myoblast fusion.
The fusion of chick embryonic myoblasts has been studied in tissue culture. Myoblasts are maintained at 0.1 microM-Ca2+ for 50 h. During this time they achieve fusion competence. Fusion is initiated by raising the medium Ca2+ concentration to 1.4 mM. A rapid breakdown of the polyphosphoinositides was detected within 3 min of Ca2+ addition. Rapid synthesis of phosphatidic acid was also detected ...
متن کاملRetinal S-antigen epitopes in vertebrate and invertebrate photoreceptors.
Monoclonal antibodies specific for the retinal S-antigen were obtained by hybridization of spleen cells from a BALB/c mouse immunized with bovine S-antigen and NS-1 myeloma cells. Five selected antibodies specifically labeled the photoreceptor cells of the retina by immunofluorescence. Whereas antibody S9E2 only reacted with bovine S-antigen, the other antibodies showed interspecies cross-react...
