TL;DR: The distribution of oxytocin, vasopressin and enkephalin immunoreactivity (IR) in the neurohypophysis of the rat is compared and it is reported here that Met-enkephaline-IR is invariably associated with nerve terminals that contain oxytocIn-IR whereas the terminals that containing vaso-pressin-IR often, but not invariably, are Leu-encephalin Immunoreactive.

TL;DR: The periodic but regular incidence of ribosomes in mature vertebrate axons provides a structural basis for previous metabolic evidence of protein synthesis in myelinated axons.

TL;DR: The intensity and frequency of leucine-enkephalin immunostaining in vasopressin terminals was much enhanced by treatment of the deplasticized sections with trypsin prior to incubation with antibodies, which suggests incorporation of the leucinescription sequence into longer peptide chains, presumably dynorphin and/or α-neo-endorphin.

TL;DR: This work sequenced expressed mRNAs from actively photosynthesizing, starved individuals of two photosynthetic sea slug species, Plakobranchus ocellatus Van Hasselt, 1824 and Elysia timida Risso, 1818, and finds that nuclear-encoded, algal-derived genes specific to Photosynthetic function are expressed neither in P. o cellatus nor in E. timida.

TL;DR: It is reported that the squid giant axon also contains active polysomes and niRNA, which hybridizes to a riboprobe encoding murine neurofilament protein, which provides direct evidence that proteins (including the putative neuron‐specific neuro Filament protein) are also synthesized de novo in the axonal compartment.
