    “…At many synapses, neurotransmitter receptor molecules in the postsynaptic membrane are selectively concentrated at a site directly opposite the presynaptic nerve terminal. In this paper, I examine acetylcholine (ACh) receptor distribution in cardiac muscle in relatin to the distribution of presynaptic axonal varicosities. …”

    “…An alteration in the rate of calcium transport appears to be the rate- limiting event for the commitment of murine erythroleukemia (MEL) cells to initiate a program of terminal erythroid differentiation. The dimethyl sulfoxide (DMSO)-induced commitment of MEL cells to erythroid differentiation can be inhibited by treatment of cells with the calcium- chelating agent EGTA. …”

    Publicado 1968
    “…No differences were found between fiber types in rates of transmitter mobilization, density of innervation, or the relationship between transmitter release and terminal depolarization. Single terminals on distal fibers were found to release transmitter with a greater probability than central terminals. …”

    Publicado 1969
    “…The loss of reactivity to repetitive stimulation has been traced to soleus motor nerve terminals. In view of these data and the known absence of denervation hypersensitivity at this time, the earliest functional failure may be said to occur in the unmyelinated terminals. …”

    “…The presynaptic localization of the specific fluorescence found at frog neuromuscular junctions is supported by two sets of findings: (a) fluorescent endplate images were not seen in muscles that had been denervated; and (b) the distribution of fluorescence in many fibers treated with alpha-latrotoxin at room temperature was the one expected from swollen terminal branches. Swelling of terminals is a known morphological change induced by alpha-latrotoxin in this preparation. …”

    “…We hypothesized that the “N-end rule”, which relates the half-life of proteins in cells to the identity of their N-terminal residue, might be operative in the case of LF, so that the N-terminal residue of LF would determine the cytosolic stability and thereby the potency of LF. …”
