Neuroscientists identify astrocytes as master 'conductors' of the brain

In the orchestra of the brain, the firing of each neuron is controlled by two notes--excitatory and inhibitory-- that come from two distinct forms of a cellular structure called synapses.

"Cat's claw" extract inhibits replication of SARS-CoV-2 in vitro

Researchers in Columbia and Peru have shown that Uncaria tomentosa – a woody vine native to South America known of as "Cat's claw" – exerts in vitro antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Men and women may require different brain tumor therapy, study finds

The current study shows that the sex differences in the tumor phenotype vary with the effect of the enhancer regulatory molecule bound to Brd4 on the course of stem cell-like differentiation in male and female GBM cells. Inhibition of Brd4 by genetic and pharmacological factors also varies in males and females, both in vivo and in vitro.

Pioneering technique sheds new light on the origin of metastases

Research can now target metastases more effectively thanks to a new approach that takes into account the enormous heterogeneity and phenotypes of tumor cells, with a team from UNIGE pinpointing a gene that prevents their development.

Exosome-mediated mRNA delivery generates broad immune response to multiple SARS-CoV-2 proteins

Recently, researchers from The Johns Hopkins University School of Medicine, Baltimore, MD, USA, and Capricor Therapeutics, Inc., Beverly Hills, CA, USA, described a new approach to SARS-CoV-2 vaccine development using exosomes to deliver mRNAs that encode the antigens from multiple structural proteins of the virus.

Immune-evading variants can emerge in SARS-CoV-2, researchers warn

An international team of researchers has shown that a mutation within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the coronavirus disease 2019 (COVID-19) – enables the pathogen to evade antibody-mediated immunity while maintaining replication fitness and increasing viral loads.

Researchers identify new strategy to combat loss of skeletal muscle mass

Researchers at the University of São Paulo (USP) in Brazil have shown for the first time that stimulating expression of a protein naturally produced by the human body can be a strategy to combat loss of skeletal muscle mass, which happens normally with aging but can intensify in cases of neurodegenerative or inflammatory disease, or in patients who spend long periods in intensive care units (ICUs).

Innate immunity key to limiting viral load in COVID-19 cases

As the coronavirus disease 2019 (COVID-19) pandemic continues to cause many difficulties for public health authorities, research is ongoing to understand how the virus can cause fatal effects on those infected and thereby suggest effective preventive and therapeutic measures against it.

Rapid generation of divergent synthetic antibodies against SARS-CoV-2 in a cell-free engineering platform

In a groundbreaking bioRxiv paper, a research group from the Massachusetts Institute of Technology (MIT), Harvard University and Howard Hughes Medical Institute in the US engineered antibodies against the receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein by using a novel approach. In doing so, they also identified more than 800 predicted binder families.

Biomarkers that are predictive of clinical benefit in Trop-2-expressing triple-negative breast cancer

Oncotarget recently published "Predictive biomarkers for sacituzumab govitecan efficacy in Trop-2-expressing triple-negative breast cancer" which reported that the authors investigated whether Trop-2-expression and homologous recombination repair of SN-38-mediated double-strand DNA breaks play a role in the sensitivity of triple-negative breast cancer to SG.

SARS-CoV-2 spike D614G variant exhibits enhanced replication and transmissibility

A team of scientists from Switzerland, Germany, and the USA has demonstrated that the S-614G variant can easily bind to the human angiotensin-converting enzyme 2 (ACE2), the cellular gateway of SARS-CoV-2. The variant also showed enhanced replication and transmissibility in animal models.
