NK Cell Subpopulation Is Altered and the Expression of TLR1 and TLR9 Is Decreased in Patients with Acute Lymphoblastic Leukemia. [PDF]
J Oncol, 2021 NK cells represent a heterogeneous subpopulation of lymphocytes of the innate immune system, which possess powerful antitumor activity. NK cells exhibit their function through a complex collection of receptors that act synergistically to recognize, regulate, or amplify the immune response.

Phenotype of Peripheral NK Cells in Latent, Active, and Meningeal Tuberculosis. [PDF]
J Immunol Res, 2021 The mechanisms underlying the immunopathology of tuberculous meningitis (TBM), the most severe clinical form of extrapulmonary tuberculosis (TB), are not understood. It is currently believed that the spread of Mycobacterium tuberculosis (Mtb) from the lung is an early event that occurs before the establishment of adaptive immunity.

Integrating transcription and splicing into cell fate: Transcription factors on the block
WIREs RNA, Volume 14, Issue 2, March/April 2023., 2023 Transcription factors (TFs) are key players of gene expression integrating transcription and splicing. Their activity is orchestrated by multiple features such as DNA/RNA‐binding affinity and co‐regulatory proteins, altogether fine‐tuned by the local nuclear environment.

Emerging roles of BET proteins in transcription and co‐transcriptional RNA processing
WIREs RNA, Volume 14, Issue 1, January/February 2023., 2023 Roles of BET proteins in RNA polymerase II transcription and co‐transcriptional RNA processing. Abstract Transcription by RNA polymerase II (Pol II) gives rise to all nuclear protein‐coding and a large set of non‐coding RNAs, and is strictly regulated and coordinated with RNA processing.

A Stable H2O Atmosphere on Europa’s Trailing Hemisphere From HST Images
Geophysical Research Letters, Volume 48, Issue 20, 28 October 2021., 2021 Abstract Previous studies of the global intensities of the oxygen emissions at 1,356 Å and 1,304 Å revealed molecular oxygen (O2) in Europa's atmosphere. Here we investigate the relative changes of the two oxygen emissions when Europa emerges from eclipse as well as the radial profiles of the relative emissions across the sunlit disk in Hubble Space ...

Modeling of Possible Plume Mechanisms on Europa
Journal of Geophysical Research: Space Physics, Volume 126, Issue 9, September 2021., 2021 Abstract Plumes spewing water high above Europa's surface have been inferred from several observation campaigns in the past decade. Whereas the occasional existence of plumes on Europa has thus been confirmed, the origin of the plumes remains uncertain.

La lettre d’amour de Giono au carrefour des émotions [PDF]
Revue Roumaine d’Etudes Francophones, 2023 The wickedness in the letters that Jean Giono sent to Blanche Meyer is a reality. In fact, the strength of the feeling of love gives rise to symptomatic emotions of a violent and immeasurable passion.

Multi‐Point Measurements of the Plasma Properties Inside an Aurora From the SPIDER Sounding Rocket
Journal of Geophysical Research: Space Physics, Volume 126, Issue 7, July 2021., 2021 Abstract The Small Payloads for Investigation of Disturbances in Electrojet by Rockets (SPIDER) sounding rocket was launched on February 2nd, 2016 (21:09 UT), deploying 10 free falling units (FFUs) inside a westward traveling auroral surge. Each FFUs deployed spherical electric field and Langmuir probes on wire‐booms, providing in situ multi‐point ...

microRNA strand selection: Unwinding the rules
WIREs RNA, Volume 12, Issue 3, May/June 2021., 2021 Summary of miRNA strand selection and regulatory mechanisms. Three major points of regulation for miRNA strand selection (1) altered miRNA processing by the Microprocessor complex (not shown) or Dicer, (2) remodeling of the miRNA duplex by nontemplated RNA modifications such as uridylation or A‐to‐I editing, and (3) changes in the strand preference of ...
