Journal ArticleDOI
Cellular mechanisms of intestine regeneration in the sea cucumber, Holothuria glaberrima Selenka (Holothuroidea:Echinodermata)
José E. García-Arrarás,Lourdes Estrada-Rodgers,Roberto Santiago,Irma I. Torres,Lucy Díaz-Miranda,Ilia Torres-Avillán +5 more
TL;DR: This study provides evidence that the process of new organ formation in holothurians can be described as an intermediate process showing characteristics of both epimorphic and morphallactic phenomena.
Journal ArticleDOI
Localization of the heptapeptide GFSKLYFamide in the sea cucumber Holothuria glaberrima (Echinodermata): a light and electron microscopic study.
TL;DR: The localization and distribution pattern of GFSKLYFa‐like immunoreactivity in H. glaberrima is described, where immunoreactive fibers form a prominent and extensive peptidergic nervous system component.
Journal ArticleDOI
Characterization of Two Novel Neuropeptides From the Sea Cucumber Holothuria glaberrima.
Lucy Díaz-Miranda,David A. Price,Michael J. Greenberg,Terry D. Lee,K. E. Doble,José E. García-Arrarás +5 more
TL;DR: Sequence similarities between GFSKLYFamide, SGYSVLYfamide, and a pair of peptides previously isolated from starfish lead us to propose that all four molecules are members of a family of peptide acting as neurotransmitters in echinoderms.
Journal ArticleDOI
Regeneration of the enteric nervous system in the sea cucumber Holothuria glaberrima.
José E. García-Arrarás,Lucy Díaz-Miranda,Irma I. Torres,Sharon File,L. Jimenez,Katherine Rivera‐Bermudez,Edgardo J. Arroyo,William Cruz +7 more
TL;DR: Evidence is provided that the enteric nervous system of this echinoderm regenerates after evisceration and that in 3–5 weeks the regenerated system is virtually identical to that of noneviscerated animals.
Journal ArticleDOI
The enteric nervous system of echinoderms: unexpected complexity revealed by neurochemical analysis
TL;DR: Information is gathered on the nervous components of the digestive tract of echinoderms and an unexpected level of complexity is demonstrated in terms of neurons, nerve plexi, their location and neurochemistry.
