Helios is a marker, not a driver, of human Treg stability.

European journal of immunology

Lam AJ, Uday P, Gillies JK, Levings MK.
PMID: 34561855
Eur J Immunol. 2021 Sep 25; doi: 10.1002/eji.202149318. Epub 2021 Sep 25.

Treg therapy holds promise as a potentially curative approach to establish immune tolerance in transplantation and autoimmune disease. An outstanding question is whether therapeutic Tregs have the potential to transdifferentiate into effector T-cells and, thus, exacerbate rather than suppress...

Jupiter's atmospheric jet streams extend thousands of kilometres deep.

Nature

Kaspi Y, Galanti E, Hubbard WB, Stevenson DJ, Bolton SJ, Iess L, Guillot T, Bloxham J, Connerney JEP, Cao H, Durante D, Folkner WM, Helled R, Ingersoll AP, Levin SM, Lunine JI, Miguel Y, Militzer B, Parisi M, Wahl SM.
PMID: 29516995
Nature. 2018 Mar 07;555(7695):223-226. doi: 10.1038/nature25793.

The depth to which Jupiter's observed east-west jet streams extend has been a long-standing question. Resolving this puzzle has been a primary goal for the Juno spacecraft, which has been in orbit around the gas giant since July 2016....

A suppression of differential rotation in Jupiter's deep interior.

Nature

Guillot T, Miguel Y, Militzer B, Hubbard WB, Kaspi Y, Galanti E, Cao H, Helled R, Wahl SM, Iess L, Folkner WM, Stevenson DJ, Lunine JI, Reese DR, Biekman A, Parisi M, Durante D, Connerney JEP, Levin SM, Bolton SJ.
PMID: 29517000
Nature. 2018 Mar 07;555(7695):227-230. doi: 10.1038/nature25775.

Jupiter's atmosphere is rotating differentially, with zones and belts rotating at speeds that differ by up to 100 metres per second. Whether this is also true of the gas giant's interior has been unknown, limiting our ability to probe...

Juno-UVS approach observations of Jupiter's auroras.

Geophysical research letters

Gladstone GR, Versteeg MH, Greathouse TK, Hue V, Davis MW, Gérard JC, Grodent DC, Bonfond B, Nichols JD, Wilson RJ, Hospodarsky GB, Bolton SJ, Levin SM, Connerney JEP, Adriani A, Kurth WS, Mauk BH, Valek P, McComas DJ, Orton GS, Bagenal F.
PMID: 28989207
Geophys Res Lett. 2017 Aug 16;44(15):7668-7675. doi: 10.1002/2017GL073377. Epub 2017 Aug 04.

Juno ultraviolet spectrograph (UVS) observations of Jupiter's aurora obtained during approach are presented. Prior to the bow shock crossing on 24 June 2016, the Juno approach provided a rare opportunity to correlate local solar wind conditions with Jovian auroral...

Organelle DNA variation and systematic relationships in the genus Zea: Teosinte.

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

Timothy DH, Levings CS, Pring DR, Conde MF, Kermicle JL.
PMID: 16592708
Proc Natl Acad Sci U S A. 1979 Sep;76(9):4220-4. doi: 10.1073/pnas.76.9.4220.

Chloroplast and mitochondrial DNAs from six races of annual teosinte (Guatemala, Huehuetenango, Balsas, Central Plateau, Chalco, and Nobogame), perennial teosinte, and maize were compared and grouped by restriction endonuclease fragment analyses. Three groups of chloroplast DNAs were detected: (i)...

Cytoplasmic Reversion of cms-S in Maize: Association with a Transpositional Event.

Science (New York, N.Y.)

Levings CS, Kim BD, Pring DR, Conde MF, Mans RJ, Laughnan JR, Gabay-Laughnan SJ.
PMID: 17747231
Science. 1980 Aug 29;209(4460):1021-3. doi: 10.1126/science.209.4460.1021.

Spontaneous reversion to fertility in S male-sterile cytoplasm of maize is correlated with the disappearance of the mitochondrial plasmid-like DNA's, S-1 and S-2, and changes in the mitochondrial chromosomal DNA. Hybridization data indicate that one of the plasmid-like DNA's,...

Nucleotide sequence of the S-2 mitochondrial DNA from the S cytoplasm of maize.

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

Levings CS, Sederoff RR.
PMID: 16593334
Proc Natl Acad Sci U S A. 1983 Jul;80(13):4055-9. doi: 10.1073/pnas.80.13.4055.

Mitochondria from the S male-sterile cytoplasm (cms-S) of maize contain two plasmid-like DNAs, S-1 and S-2, that appear to be prominently involved with the cytoplasmic male sterility trait. The complete nucleotide sequence of the S-2 DNA molecule was determined...

The Texas cytoplasm of maize: cytoplasmic male sterility and disease susceptibility.

Science (New York, N.Y.)

Levings CS.
PMID: 17746917
Science. 1990 Nov 16;250(4983):942-7. doi: 10.1126/science.250.4983.942.

The Texas cytoplasm of maize carries two cytoplasmically inherited traits, male sterility and disease susceptibility, which have been of great interest both for basic research and plant breeding. The two traits are inseparable and are associated with an unusual...

Collective experiences of adventitious viruses of animal-derived raw materials and what can be done about them.

Cytotechnology

Wessman SJ, Levings RL.
PMID: 19003405
Cytotechnology. 1998 Nov;28(1):43-8. doi: 10.1023/A:1008005026243.

Contamination of animal-derived raw materials with viruses, mycoplasmas, bacteria and fungi is common. These contaminants can interfere with the diagnosis of viral infection, and vaccines produced using infected cell cultures could lead to seroconversion or disease in the vaccinated...
