Controlling polymer shape through the self-assembly of dendritic side-groups

Article Abstract:

It has been possible to develop a general strategy for the rational control of polymer conformation through the self-assembly of quasi-equivalent monodendritic (branched) side-groups connected to flexible backbones. Researchers identified a correlation between polymer conformation and polymerization (DP) which is opposite to that observed in most synthetic and natural macromolecules. The general design concept has been tested on a range of quasi-equivalent dendritic monomers with different architecture, polymer backbone and generation number.

Qa-2 molecules are peptide receptors of higher stringency than ordinary class I molecules

Article Abstract:

Natural ligands of glycophosphatidyl-anchored mouse class I major histocompatibility complex molecules are distinctly specialized peptide receptors whose purpose remains unknown. They have similar ligand specificity and peptide binding grooves to the traditional class I molecules and yet, of their nine binding sites, two are anchors and four are limited binders. This pool sequencing suggests a very specific function for the molecules which is possibly the presentation of epithelial-pathogen derived antigens to gamma upsilon T cells.
