Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

In-Flow Flash Nanoprecipitation of Size-Controlled D-Leucine Nanoparticles for Spray-Drying Formulations

, 2019
In this work we report the development of a cheap and scalable flow-based flash nanoprecipitation approach to prepare D-leucine nanoparticles particularly useful as glidants in dry powder for inhalation.

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

Aging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Branched-chain amino acids and muscle protein synthesis in humans: myth or reality?

Journal of the International Society of Sports Nutrition, 2017
The branched chain amino acids (BCAAs) are leucine, valine and isoleucine. A multi-million dollar industry of nutritional supplements has grown around the concept that dietary supplements of BCAAs alone produce an anabolic response in humans driven by a ...

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

A Systematic Review and Meta‐Analysis of the Recurrence of Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autoimmune encephalitis (AE) is a disease with a potential for recurrence, and patients receive immunotherapy to prevent it. However, there is no consensus on the duration of immunotherapy. This study aimed to determine the recurrence rate and identify the risk factors for AE to provide guidance on the duration of immunotherapy ...

Persistent Bilateral [18F]THK5351 and Migrating Unilateral [18F]FDG Uptake in Anti‐LGI1 Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Anti–leucine‐rich glioma‐inactivated 1 encephalitis (LGI1‐E) can cause persistent cognitive deficits, but the mechanisms remain unclear. A 40‐year‐old woman with LGI1‐E presented with subacute cognitive deficits and showed mild left medial temporal lobe (MTL) swelling and fluid‐attenuated inversion recovery (FLAIR) hyperintensity on initial ...

Leucine Supplementation Prevents the Development of Skeletal Muscle Dysfunction in a Rat Model of HFpEF

Cells
Heart failure with preserved ejection fraction (HFpEF) is associated with exercise intolerance due to alterations in the skeletal muscle (SKM). Leucine supplementation is known to alter the anabolic/catabolic balance and to improve mitochondrial function.

EFFICIENT LEUCINE TRANSPORT ACROSS THE PLACENTAL BARRIER DEPENDS ON PHYSIOLOGICAL, OPPOSITELY DIRECTED LEUCINE GRADIENTS

, 2019
Objectives: We aimed to assess the concentrations and importance of physiological amino acid (AA) gradients between the maternal and fetal compartments to determine the transport activity of leucine using a 3D in vitro model with trophoblast cells ...
