Fig.Figure 8(A) A tension-less protein-lined metastable fusion pore formed between two mixed (3:2, PC:PE) model membranes (POPC head groups colored light brown, POPE head groups colored orange). The radius of the pore is 1.5 nm. The yellow sphere mimics a steric perturbation on the fusion site imposed by HOPS binding to one of the SNARE complexes. The upper panel shows a cross section of this pore in side view. The lower panels show side views of cross sections through this 1.5 nm pore, which is at the free energy minimum, as well as of a 3 nm pore, which is at the threshold where the line tension converges to a constant value Notice that the cross-sectional shape of the pore (shown in top views) remains largely spherical despite the heterogeneity of the fusion site. The top view show also a fluorescent dye molecule (dichlorofluorescein, MW=401 Da, in purple) to illustrate its scale relative to the 1.5 nm pore. (B) Line tension of the fusion pore in pN as function of pore radius and the fusion proteins inserted into it. The black dotted line represents the position of the local minimum. The initial expansion is relatively insensitive to the presence of fusion proteins. Each data point represents the average line tension measured over an ~600 ns equilibrium simulation. Error bars are based on block averaging over the obtained data set (the autocorrelation time is ~30 ns).
Figure 4Three general motifs of intracellular antibiotic action. Left and middle motifs correspond to ribosome-inhibiting antibiotics that induce rapid and minimal ribosome degradation, respectively. In these motifs, the target molecule is subject to nonlinear positive feedback (i.e. transcription and translation, in the case of ribosomes). Right motif corresponds to antibiotics that inhibit other targets that are not subject to positive feedback, e.g. β-lactams. In each case, recovery time is a function of total antibiotic exposure (closed circles) and inhibiting efflux results in longer recovery times (open circles). Inhibiting antibiotic efflux with CCCP significantly increased recovery time for antibiotics that induced rapid target degradation and involved a positive feedback loop. Antibiotics are as follows: penicillin G (PenG), spectinomycin (Spec), gentamicin (Gent), streptomycin (Str), chloramphenicol (Cm), tetracyclin (Tet), and carbenicillin (Carb). Antibiotic concentrations used have been scaled by their respective IC50 values (solid points and open circles show response with no efflux inhibition and 2μg/mL CCCP, respectively). Colors correspond to the motifs of action shown in Figure 4A.
Figure 4Using the IFT marker BBS-7, cilia lengths were measured for wild-type and the ts-che-3 mutant animals raised at the permissive (15ºC) and shifted to the restrictive temperature (25ºC) for three time points. After 12 hours some accumulations (indicated by asterisks in the fluorescence images) are observed within the cilia but there is not a significant reduction in cilium length. After 18 and 24 hours, significant reduction in ciliary length is observed and large accumulations of BBS-7 is seen within short bulbous cilia, similar to what is observed in ts-che-3 animals raised at the restrictive temperature. n = 30-34 cilia, one per animal; Kruskal-Wallis test, **P<0.01; error bars are mean absolute deviation; scale bars are 4 µm IFT velocities were measured for wild-type or ts-che-3 mutant animals (grown at permissive temperature) and imaged at the permissive temperature, restrictive temperature or after 3 hours at the restrictive temperature. Compared to wild-type, anterograde velocities in the ts-che-3 dynein mutant are similar, while IFT retrograde rates are highly reduced for both the middle and distal ciliary segments. Interestingly, the ts-che-3 IFT dynein mutant appears to not only have slow retrograde IFT trains, but the trains also appear much larger and less frequent. Initially upon the temperature shift (<15min) IFT rates are much faster for both wild-type and ts-che-3 dynein mutant, although retrograde remains much slower in the mutant. After 3 hours at the restrictive temperature, IFT velocities are intermediate between the rates seen at 15ºC and those observed at the initial shift to 25ºC
