Granular convection and the Brazil nut effect in reduced gravity.

Physical review. E, Statistical, nonlinear, and soft matter physics

Güttler C, von Borstel I, Schräpler R, Blum J.
PMID: 23679551
Phys Rev E Stat Nonlin Soft Matter Phys. 2013 Apr;87(4):044201. doi: 10.1103/PhysRevE.87.044201. Epub 2013 Apr 23.

We present laboratory experiments of a vertically vibrated granular medium consisting of 1-mm-diameter glass beads with embedded 8-mm-diameter intruder glass beads. The experiments were performed in the laboratory as well as in a parabolic flight under reduced-gravity conditions (on...

Selective uptake of pyrrolizidine N-oxides by cell suspension cultures from pyrrolizidine alkaloid producing plants.

Plant cell reports

von Borstel K, Hartmann T.
PMID: 24247963
Plant Cell Rep. 1986 Feb;5(1):39-42. doi: 10.1007/BF00269714.

The N-oxides of pyrrolizidine alkaloids such as senecionine or monocrotaline are rapidly taken up and accumulated by cell suspension cultures obtained from plants known to produce pyrrolizidines, i.e. Senecio vernalis, vulgaris, viscosus (Asteraceae) and Symphytum officinale (Boraginaceae). The transport...

Absence of mucosal-associated invariant T cells in a person with a homozygous point mutation in .

Science immunology

Howson LJ, Awad W, von Borstel A, Lim HJ, McWilliam HEG, Sandoval-Romero ML, Majumdar S, Hamzeh AR, Andrews TD, McDermott DH, Murphy PM, Le Nours J, Mak JYW, Liu L, Fairlie DP, McCluskey J, Villadangos JA, Cook MC, Turner SJ, Davey MS, Ojaimi S, Rossjohn J.
PMID: 32709702
Sci Immunol. 2020 Jul 24;5(49). doi: 10.1126/sciimmunol.abc9492.

The role unconventional T cells play in protective immunity in humans is unclear. Mucosal-associated invariant T (MAIT) cells are an unconventional T cell subset restricted to the antigen-presenting molecule MR1. Here, we report the discovery of a patient homozygous...

BCG Provides Short-Term Protection from Experimental Cerebral Malaria in Mice.

Vaccines

Witschkowski J, Behrends J, Frank R, Eggers L, von Borstel L, Hertz D, Mueller AK, Schneider BE.
PMID: 33316929
Vaccines (Basel). 2020 Dec 09;8(4). doi: 10.3390/vaccines8040745.

Clinical and experimental evidence suggests that the tuberculosis vaccine BCG offers protection against unrelated pathogens including the malaria parasite. Cerebral malaria (CM) is the most severe complication associated with

Recognition of the antigen-presenting molecule MR1 by a Vδ3.

Proceedings of the National Academy of Sciences of the United States of America

Rice MT, von Borstel A, Chevour P, Awad W, Howson LJ, Littler DR, Gherardin NA, Le Nours J, Giles EM, Berry R, Godfrey DI, Davey MS, Rossjohn J, Gully BS.

Unlike conventional αβ T cells, γδ T cells typically recognize nonpeptide ligands independently of major histocompatibility complex (MHC) restriction. Accordingly, the γδ T cell receptor (TCR) can potentially recognize a wide array of ligands; however, few ligands have been...

Alkaloid N-oxides as transport and vacuolar storage compounds of pyrrolizidine alkaloids in Senecio vulgaris L.

Planta

Ehmke A, von Borstel K, Hartmann T.
PMID: 24220738
Planta. 1988 Nov;176(1):83-90. doi: 10.1007/BF00392483.

Cell-suspension cultures of pyrrolizidinealkaloid-producing species selectively take up and accumulate senecionine (sen) and its N-oxide (sen-Nox). Cultures established from non-alkaloid-producing species are unable to accumulate the alkaloids. The uptake and accumulation of (14)C-labelled alkaloids was studied using a Senecio...
