Microtubules in cone myoid elongation in the teleost retina
The myoids of retinal cone cells of the blue-striped grunt (Haemulon sciurus) undergo significant elongation during dark adaptation of the retina. Longitudinally oriented microtubules are present in myoids both before and after elongation. Injection of colchicine into the vitreous of the eye in vivo disrupts the microtubules in the myoids and prevents dark-adaptive myoid elongation. Counts of m...
متن کاملThin (actin) and thick (myosinlike) filaments in cone contraction in the teleost retina
The long slender retinal cones of fishes shorten in the light and elongate in the dark. Light-induced cone shortening provides a useful model for stuying nonmuscle contraction because it is linear, slow, and repetitive. Cone cells contain both thin (actin) and thick (myosinlike) filaments oriented parallel to the axis of contraction. This study examines the polarities of the cone's thin filamen...
متن کاملIGF-1 produced by cone photoreceptors regulates rod progenitor proliferation in the teleost retina.
Teleost eyes grow throughout life by adding neurons and stretching extant tissue. New retinal neurons of all types are added at the ciliary margin and new rod photoreceptors are inserted throughout retina in the outer nuclear layer (ONL). New rod photoreceptors result from the division of progenitor cells located in the ONL amidst functioning rod photoreceptor cell nuclei, but it is not known h...
متن کاملMicrotubule polarity and distribution in teleost photoreceptors.
We have characterized the polarity orientation of microtubules in teleost retinal photoreceptors. The highly polarized rods and cones contain large numbers of paraxially aligned microtubules and exhibit dramatic cell shape changes. The myoid portion of the inner segments of both rods and cones undergoes contraction and elongation in response to light or circadian signals. Previous studies in ou...
