Enhanced antigen presentation and immunostimulation of dendritic cells using acid-degradable cationic nanoparticles.
Acid-degradable cationic nanoparticles encapsulating a model antigen (i.e., ovalbumin) were prepared by inverse microemulsion polymerization with acid-cleavable acetal cross-linkers. Incubation of these degradable nanoparticles with dendritic cells derived from bone marrow (BMDCs) resulted in the enhanced presentation of ovalbumin-derived peptides, as quantified by B3Z cells, a CD8+ T cell hybridoma. The cationic nature of the particles contributed to the increased surface endocytosis (or phagocytosis) observed with BMDCs, which is the first barrier to overcome for successful antigen delivery. The acid sensitivity of the particles served to direct more ovalbumin antigens to be processed into the appropriately trimmed peptide fragments and presented via the major histocompatibility complex (MHC) class I pathway following hydrolysis within the acidic lysosomes. It was also shown that adjuvant molecules such as unmethylated CpG oligonucleotides (CpG ODN) and anti-interleukin-10 oligonucleotides (AS10 ODN) could be co-delivered with the protein antigen for maximized cellular immune response
The Kolmogorov-Riesz compactness theorem
We show that the Arzela-Ascoli theorem and Kolmogorov compactness theorem
both are consequences of a simple lemma on compactness in metric spaces. Their
relation to Helly's theorem is discussed. The paper contains a detailed
discussion on the historical background of the Kolmogorov compactness theorem.Comment: This version is lightly revised in response to referee comments. The
paper will appear in Expositiones Mathematica
trans-CycloÂhex-2-ene-1,4-diyl bisÂ(4-nitroÂphenÂyl) dicarbonate
Although the title molÂecule, C20H16N2O10, does not possess molÂecular inversion symmetry, it lies on a crystallographic inversion centre which imposes disorder on the central cycloÂhexene ring. In addition, the cycloÂhexene ring has non-symmetry-related disorder over two sites, with the ratio of the major and minor components being 0.54:0.46. The overall effect is to produce four disorder components for the atoms of the cycloÂhexene ring. The side chain is perfectly ordered and the dihedral angle between the atoms of the carbonate group (O=CO2—) and the benzene ring is 72.99 (6)°
A Fr\'{e}chet law and an Erd\"os-Philipp law for maximal cuspidal windings
In this paper we establish a Fr\'{e}chet law for maximal cuspidal windings of
the geodesic flow on a Riemannian surface associated with an arbitrary finitely
generated, essentially free Fuchsian group with parabolic elements. This result
extends previous work by Galambos and Dolgopyat and is obtained by applying
Extreme Value Theory. Subsequently, we show that this law gives rise to an
Erd\"os-Philipp law and to various generalised Khintchine-type results for
maximal cuspidal windings. These results strengthen previous results by
Sullivan, Stratmann and Velani for Kleinian groups, and extend earlier work by
Philipp on continued fractions, which was inspired by a conjecture of Erd\"os
