Ocular conjunctival inoculation of SARS-CoV-2 can cause mild COVID-19 in rhesus macaques

Nature Communications, 2020
SARS-CoV-2 mainly transmits via respiratory droplets. Here Deng et al. show that SARS-CoV-2 can infect rhesus macaques via ocular conjunctival inoculation.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

The development of brain magnetic resonance approaches in large animal models for preclinical research [PDF]

, 2019
International audienceMagnetic resonance imaging is a very powerful ap-proach to perform anatomical and functional imaging explorations. Large animal models are perfectly suited for MRI studies using clinical devices and these tools are cur-rently being ...

Association between genetically proxied PPARG activation and early onset Alzheimer's disease: A drug target Mendelian randomization study

Journal of Alzheimer's Disease Reports
Background:  Early-onset Alzheimer's disease (EOAD), which has an onset before the age of 65, is overshadowed by the more prevalent late-onset Alzheimer's disease (LOAD).

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Lipopolysaccharide Increases Immune Activation and Alters T Cell Homeostasis in SHIVB’WHU Chronically Infected Chinese Rhesus Macaque

Journal of Immunology Research, 2015
Immune activation plays a significant role in the disease progression of HIV. Microbial products, especially bacterial lipopolysaccharide (LPS), contribute to immune activation.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Lysyl oxidase (LOX)‐mediated remodeling of the extracellular matrix

FEBS Letters, EarlyView.
The lysyl oxidase (LOX) family of enzymes drives extracellular matrix remodeling by oxidizing collagen, elastin, and fibronectin, promoting covalent cross‐link formation. This activity regulates tissue architecture and mechanical properties, while its dysregulation contributes to fibrosis, cardiovascular disease, glaucoma, connective tissue disorders ...

New Methods for Integrated Models of Animal Disease Control [PDF]

Accurate assessments of the epidemiological and economic impacts of an animal disease require the incorporation of feedbacks between disease spread and production incentives. This paper motivates a new modeling framework that is sensitive to the dynamics
