Dendritic cells use macropinocytosis and the mannose receptor to concentrate macromolecules in the major histocompatibility complex class II compartment: downregulation by cytokines and bacterial
The capacity of DCs to capture and process antigen could be modulated by exogenous stimuli was investigated and it was found that DCs respond to tumor necrosis factor alpha, CD40 ligand, IL-1, and lipopolysaccharide with a coordinate series of changes that include downregulation of macropinocytosis and Fc receptors, disappearance of the class II compartment, and upregulation of adhesion and costimulatory molecules.

Quantum tunnelling of the magnetization in a monolayer of oriented single-molecule magnets
The findings prove that the quantum spin dynamics can be observed in SMMs chemically grafted to surfaces, and offer a tool to reveal the organization of matter at the nanoscale. Expand
Magnetic memory of a single-molecule quantum magnet wired to a gold surface.
The road is now open to address individual molecules wired to a conducting surface in their blocked magnetization state, thereby enabling investigation of the elementary interactions between electron transport and magnetism degrees of freedom at the molecular scale. Expand
Magnetostructural correlations in Tetrairon(III) single-molecule magnets.
The zero-field splitting parameter D of the ground S=5 spin state correlates strongly with the pitch of the propeller gamma, and thus provides a simple link between molecular structure and magnetic behavior. Expand
Deposition of intact tetrairon(III) single molecule magnet monolayers on gold: an STM, XPS, and ToF-SIMS investigation
The ability of a tetranuclear iron(III) single-molecule magnet functionalized with thioacetyl-terminated ligands to form monolayers on gold has been investigated by a multitechnique approach based onExpand
Electric field controlled magnetic anisotropy in a single molecule.
It is demonstrated that the molecule retains its magnetic properties and, moreover, that the magnetic anisotropy is significantly enhanced by reversible electron addition/subtraction controlled with the gate voltage, suggesting that single-molecule magnetism can be electrically controlled. Expand
Single-molecule-magnet carbon-nanotube hybrids.
The assembly of CNT–SMM hybrids using a tailor-made tetrairon(III) SMM, [Fe4(L)2(dpm)6] (1; Hdpm= dipivaloylmethane), designed to graft onto the walls of C NTs is reported. Expand
Release of DR molecules from complexes with invariant chain through the formation of a C-terminal 25 kDa invariant chain fragment.
The p25 fragment, which is produced by proteolytic cleavage at the N-terminal side of Methionine 107, has a decreased affinity for DR molecules as compared with the p33/35 species. Expand
A short approach to chaetomellic anhydride A from 2,2-dichloropalmitic acid : elucidation of the mechanism governing the functional rearrangement of the chlorinated pyrrolidin-2-one intermediate
Abstract Chaetomellic anhydride A was efficiently attained in three steps, starting from 2,2-dichloropalmitic acid and 2-(3-chloro-2-propenylamino)pyridine. Atom transfer radical cyclisationExpand
Inhibition of peptide binding to DR molecules by a leupeptin-induced invariant chain fragment.
It is demonstrated that association with LIP fragments is sufficient to prevent binding of peptides by DR molecules, while the extracytoplasmic portion of Ii, though capable of associating withDR molecules, lacks the capacity to block peptide binding. Expand
