Toll-like receptor agonist lipopeptides self-assemble into distinct nanostructures.
The self-assembled structure of toll-like receptor agonist lipopeptides containing the CSK4 peptide sequence is examined in aqueous solution. A remarkable dependence of morphology on the number of attached hexadecyl lipid chains is demonstrated, with spherical micelle structures for mono- and di-lipidated structures observed, but flexible wormlike micelles for the homologue containing three lip...
متن کاملUltrasmall Peptides Self-Assemble into Diverse Nanostructures: Morphological Evaluation and Potential Implications
In this study, we perform a morphological evaluation of the diverse nanostructures formed by varying concentration and amino acid sequence of a unique class of ultrasmall self-assembling peptides. We modified these peptides by replacing the aliphatic amino acid at the C-aliphatic terminus with different aromatic amino acids. We tracked the effect of introducing aromatic residues on self-assembl...
متن کاملModified Polyethylenimine: Self Assemble Nanoparticle Forming Polymer for pDNA Delivery
Objective Polyethylenimine (PEI), a readily available synthetic polycation which has high transfection efficiency owing to its buffering capacity was introduced for transfection a few years ago. But it has been reported that PEI is cytotoxic in many cell lines. In this study, in order to enhance the transfection efficiency of 10 kDa PEI and reduce its toxicity, hydrophobic residues were grafte...
متن کاملAre Presynaptic Proteins Predisposed to Self-Assemble?
Tight control of synapse formation ensures that neurons connect to appropriate targets. In this issue of Neuron, Klassen et al. identify ARL-8 GTPase as a regulator of presynaptic assembly. Without ARL-8, presynaptic material aggregates en route to its destination, suggesting that ARL-8 acts like a dispersant to prevent premature synaptic assembly in the axon.
