Novel calpain families and novel mechanisms for calpain regulation in Aplysia. [PDF]

open access: yesPLoS ONE, 2017
Calpains are a family of intracellular proteases defined by a conserved protease domain. In the marine mollusk Aplysia californica, calpains are important for the induction of long-term synaptic plasticity and memory, at least in part by cleaving protein

Characterization of an Aplysia vasotocin signaling system and actions of posttranslational modifications and individual residues of the ligand on receptor activity

open access: yesFrontiers in Pharmacology, 2023
The vasopressin/oxytocin signaling system is present in both protostomes and deuterostomes and plays various physiological roles. Although there were reports for both vasopressin-like peptides and receptors in mollusc Lymnaea and Octopus, no precursor or

Molecular Weight Distribution of Proteins Synthesized in Single, Identified Neurons of Aplysia [PDF]

open access: yes, 1971
Parietovisceral ganglia from Aplysia californica were incubated in medium containing leucine-3H. Single, identified nerve cell somas were isolated from the ganglia, and their proteins extracted and separated by electrophoresis on 5% SDS-polyacrylamide ...

Release of vasopressin from isolated permeabilized neurosecretory nerve terminals is blocked by the light chain of botulinum A toxin [PDF]

open access: yes, 1990
The intracellular action on exocytosis of botulinim A toxin and constituent chains was studied using permeabilized isolated nerve endings from the rat neural lobe. The release of the neuropeptide vasopressin was measured by radioimmunoassay.

Event Timing in Associative Learning [PDF]

open access: yes, 2012
Associative learning relies on event timing. Fruit flies for example, once trained with an odour that precedes electric shock, subsequently avoid this odour (punishment learning); if, on the other hand the odour follows the shock during training, it is ...

Halogenated Metabolites from the Diet of Aplysia dactylomela Rang

open access: yesMolecules, 2020
Invertebrates are an important source of structurally-diverse and biologically-active halogenated metabolites. The sea hare Aplysia dactylomela Rang has long been known to possess halogenated metabolites of dietary origin that are used as a self-defense ...

Detection of a chemical cue from the host seaweed Laurencia dendroidea by the associated mollusc Aplysia brasiliana. [PDF]

open access: yesPLoS ONE, 2017
Chemical cues from sessile hosts can attract mobile and associated organisms and they are also impotant to maintain associations and overall biodiversity, but the identity and molecular structures of these chemicals have been little explored in the ...

Untangling the Gordian Knot of Aplysia sea hare egg masses: An integrated open-hardware system for standardized egg strand sizing and packaging for cryopreservation research and application

open access: yesHardwareX, 2023
The California sea hare (Aplysia californica) provides a powerful biomedical model system for studying aspects of neurological development and damage, behavior, aging, and hypoxia.

Electrophysiological Organization of the Eye of Aplysia [PDF]

open access: yes, 1969
The eye of Aplysia californica was studied by electrophysiological and histological methods. It has a central spheroidal lens which is surrounded by a retina composed of several thousand receptor cells which are replete with clear vesicles, pigmented ...

Molecular determinants of agonist selectivity in glutamate-gated chloride channels which likely explain the agonist selectivity of the vertebrate glycine and GABAA-ρ receptors. [PDF]

open access: yesPLoS ONE, 2014
Orthologous Cys-loop glutamate-gated chloride channels (GluClR's) have been cloned and described electrophysiologically and pharmacologically in arthropods and nematodes (both members of the invertebrate ecdysozoan superphylum).
