Characterization of folded conformations in a tetrapeptide containing two tryptophan residues by vibrational circular dichroism
Authors: Petrovic Ana G. , Polavarapu Prasad L. , Mahalakshmi R. , Balaram P. 
Published: September 2009

AbstractThe intramolecularly hydrogen bonded conformations of the tetrapeptide Boc‐Trp‐Aib‐Gly‐Trp‐OMe (WUGW) are investigated using experimental and quantum chemical predictions of vibrational circular dichroism (VCD) in the 1800–1550 cm−1 region. The predicted VCD spectrum, for a conformation (conformer A) obtained from optimization of crystal structure, reproduced the dominant negative VCD band observed experimentally in CH3OH and CHCl3 solvents. However, the predicted VCD spectrum of Conformation A also has an extra positive band which is not seen in the experimental spectra. This mismatch appears to be due to the lack of solvent influence in the quantum chemical geometry optimizations. However, Conformations I and II, obtained, respectively, from constrained optimization of crystal and NMR structures, mimic the solvent stabilized structures and are predicted to have dominant negative VCD band as found in the experimental spectra. It is noted that, for the peptide investigated here, unconstrained quantum chemical geometry optimizations in vacuum converged to structures that are not the realistic models of conformations found in solution. It is also noted that undertaking quantum chemical vibrational property calculations directly using geometries obtained from crystal data or NMR data resulted in unrealistic vibrational frequencies and descriptions. However, constraining the backbone dihedral angles to those found in condensed medium, and optimizing the remaining geometrical parameters resulted in a better reproduction of the observed VCD in condensed medium. The vibrational origins of bands in all of the predicted VCD spectra for the WUGW‐tetrapeptide have also been presented. Chirality 21:E76–E85, 2009. © 2009 Wiley‐Liss, Inc.
Macroscopic Properties of Phospholipid Vesicles with a Contact Angle between the Membrane Domains
Authors: Božič Bojan , Majhenc Janja 
Published: September 2009

AbstractTernary mixtures of a high‐melting lipid, a low‐melting lipid, and cholesterol are known to form domains of a liquid‐ordered and a liquid‐disordered phase in bilayer membranes. We prepare giant vesicles from a sphingomyelin/dioleoylphosphocholine/cholesterol mixture and then examine them using fluorescence microscopy. NBD‐labeled lipid and BODIPY‐labeled cholesterol are used to identify the phase domains of the membrane. A vesicle with only two domains, one in a liquid‐ordered and one in a liquid‐disordered phase, is chosen because of its simple geometry, for convenient comparison of the experimental results with the theoretical predictions. A microinjector is used to gradually decrease and/or increase the volume of the vesicles by changing the osmolarity of the sugar solution. The relevant energy terms of the membrane mechanics are the elastic energies of the domains and the energy of the domain boundary. The elastic energy of the membrane domains can be described by two terms: the bending energy and the Gaussian bending energy. The energy of the domain boundary is proportional to its length. At the boundary between the domains a contact angle is taken into consideration. Then, in order to obtain values for the lateral tension and the contact angle, the areas of the domains and the characteristic dimensions of the shape are determined for different volumes. The best fits were obtained for a line tension of 6±3 pN and a contact angle of 1.4±0.3 rad.
Ensemble Measurement of Diffusion: Novel Beauty and Evidence

Published: September 2009

AbstractRecording the evolution of concentration profiles in nanoporous materials opens a new field of diffusion research with particle ensembles. The technique is based on the complementary application of interference microscopy and IR micro‐imaging. Combining the virtues of diffusion measurements with solids and fluids, it provides information of unprecedented wealth and visual power on transport phenomena in molecular ensembles. These phenomena include the diverging uptake and release patterns for concentration‐dependent diffusivities, the mechanisms of mass transfer at the fluid–solid interface and opposing tendencies in local and global concentration evolution.
SERS in Salt Wells
Authors: Kumar G. V. Pavan , Irudayaraj Joseph 
Published: September 2009

AbstractWe report herein a simple, inexpensive fabrication methodology of salt microwells, and define the utility of the latter as nanoparticle containers for highly sensitive surface‐enhanced Raman scattering (SERS) studies. AFM characterization of Ag and Au loaded salt microwells reveal the ability to contain favorable nanostructures such as nanoparticle dimers, which can significantly enhance the Raman intensity of molecules. By performing diffraction‐limited confocal Raman microscopy on salt microwells, we show high sensitivity and fidelity in the detection of dyes, peptides, and proteins, as a proof of our concept. The SERS limit of detection (accumulation time of 1 s) for rhodamine B and TAT contained in salt mircowells is 10 pM and 1 nM, respectively. The Raman characterization measurements of salt microwells with three different laser lines (532 nm, 632.81 nm, 785 nm) reveal low background intensity and high signal‐to‐noise ratio upon nanoparticle loading, which makes them suitable for enhanced Raman detection. SERS mapping of these sub‐femtoliter containers show spatial confinement of the relevant analyte to a few microns, which make them potential candidates for microscale bioreactors.
Cathepsin X cleaves the β2 cytoplasmic tail of LFA‐1 inducing the intermediate affinity form of LFA‐1 and α‐actinin‐1 binding

Published: September 2009

AbstractThe motility of T cells depends on the dynamic spatial regulation of integrin‐mediated adhesion and de‐adhesion. Cathepsin X, a cysteine protease, has been shown to regulate T‐cell migration by interaction with lymphocyte function associated antigen‐1 (LFA‐1). LFA‐1 adhesion to the ICAM‐1 is controlled by the association of actin‐binding proteins with the cytoplasmic tail of the β2 chain of LFA‐1. Cleavage by cathepsin X of the amino acid residues S769, E768 and A767 from the C‐terminal of the β2 cytoplasmic tail of LFA‐1 is shown to promote binding of the actin‐binding protein α‐actinin‐1. Furthermore, cathepsin X overexpression reduced LFA‐1 clustering and induced an intermediate affinity LFA‐1 conformation that is known to associate with α‐actinin‐1. Increased levels of intermediate affinity LFA‐1 resulted in augmented cell spreading due to reduced attachment of T cells to the ICAM‐1‐coated surface. Gradual cleavage of LFA‐1 by cathepsin X enables the transition between intermediate and high affinity LFA‐1, an event that is crucial for effective T‐cell migration.
Establishment of nematode infection despite increased Th2 responses and immunopathology after selective depletion of Foxp3+ cells

Published: September 2009

AbstractHere, we show that Treg limit intestinal pathology during nematode infection and that they control the onset and magnitude of the anti‐parasitic Th Th2 response. Using mice expressing the diptheria toxin receptor under the control of the foxp3 locus, we removed Foxp3+ Treg during the early phase of infection with Heligmosomoides polygyrus bakeri. Depletion of Treg in infected animals did not affect adult worm burden, but led to increased pathology at the site of infection. Infected, depleted mice displayed higher frequencies of activated CD4+ T cells and increased levels of the Th2 cytokines IL‐4 and IL‐13. The stronger parasite‐specific Th2 response was accompanied by higher levels of IL‐10. Only a moderate change in Th1 (IFN‐γ) reactivity was detected in worm‐infected, Treg‐depleted mice. Furthermore, we detected an accelerated onset of parasite‐specific Th2 and IL‐10 responses in the transient absence of Foxp3+ Treg. However, adult worm burdens were not affected by the increased Th2‐reactivity in Treg‐depleted mice. Hence, our data show that Treg restrict the onset and strength of Th2 responses during intestinal worm infection, while increasing primary Th2 responses does not necessarily lead to killing of larvae or accelerated expulsion of adult worms.
