    New England Biolabs yeast expression vector pfl61
    Figure 7. PbAtg8 does not localize to autophagosomes in dying parasites ( A ) and cannot complement yeast Atg8 ( B ). ( A ) HepG2 cells were infected with P. berghei parasites constitutively expressing mCherry (mCherry). 60 hpi the cells were fixed and stained with an anti-PbACP antiserum (ACP) to label the apicoplast and an anti-PbAtg8 antiserum (PbAtg8) to monitor the localization of this protein during parasite cell death. DNA was labeled with DAPI. A representative parasite showing strong vacuolization is depicted. A higher magnification of some important details is presented in the merged image. Scale bar: 10 µm: CPS. ( B ) Scatg8Δ and wt strains were transformed with empty <t>pFL61</t> plasmid or the same plasmid containing PbAtg8 or ScAtg8 as a positive control. Western blot analysis was performed with the transformed strains using anti-aminopeptidase I antibodies. Transport of prApe1 to the vacuole where it matures (Ape1) only takes place in the presence of a functional autophagy pathway. The prApe1 and the Ape1 bands are marked with arrows.

(A) Scheme showing the possible fates of the pBAC11.32TW12.32GLII HAC seeding DNA after transfection in HT1080: in yellow and green (as integration or HAC) is represented the synthetic DNA. Timeline of the experiments performed from transfection into HT1080 cells. (B) BAC copy number (y axis) analyzed by qPCR in each HT1080 clone (x axis): only HT1080 clones containing > 20 BAC copies are represented in the graph.

Black arrows indicate the clones shown in C and analyzed further. (C) Representative pictures of oligo-FISH staining of HT1080 clones: slides have been hybridized with DNA probes (TetO-dig/rhodamine -dig antibody, Gal4-biotin and LacO-biotin/Fitc-streptavidin). DAPI stains DNA. Scalebar = 10µm. (D) Southern blot of selected HT1080 clonal DNA (as labelled on top of the panel) digested with BamHI and separated by CHEF; the transferred membrane was hybridized with radioactively labelled TetO (left) or LacO (right) specific probes. Red arrows indicate the expected size of the band without rearrangements. Clones labelled in red have been screened further (M and m, markers).

    Distribution of AcP2X in the CNS of Aplysia and the effect of ATP on Aplysia F-cluster neurons. ( A , B ) AcP2X is expressed in neurons of the cerebral F-cluster (in situ hybridization). A pair of giant serotonergic feeding interneurons (MCC) are indicated by arrows. ( A ) The preparation embedded in a mounting media. ( B ) The cerebral ganglion was photographed in 100% ethanol. Scale 300 µm. ( C ) Current-clamp recording from F-cluster neurons in the intact CNS. Bath application of ATP (2.0 mM) caused an excitatory response with spiking activity (2–5 mV depolarization with a burst of the action potentials), and full recovery following washout (indicated by arrows) (n = 7, neurons). ( D ) Voltage-clamp recording from F-cluster neuron. Raw traces were recorded in response to 2.0 mM of ATP at three holding potentials (agonist application indicated by the line).
