Vitamin K prevents cell death: a new function for a long-known molecule

Vitamin K is well-known for its blood clotting and bone building properties but today a new study published in Nature reports on a novel function for vitamin K.

The researchers discovered that the fully reduced form of vitamin K acts as an antioxidant efficiently inhibiting ferroptotic cell death. Ferroptosis is a natural form of cell death in which cellular iron plays an important role and which is characterized by the oxidative destruction of cellular membranes.

Disparities in United States COVID-19 vaccine distribution

When reports showed COVID-19 vaccination rates were lower among racial/ethnic minority groups, most discussions focused on mistrust and misinformation among these populations or their reduced access to health care facilities. But new research from University of California San Diego and collaborating institutions has identified an additional barrier to equity: whether or not each health care facility actually received and administered vaccines.

New needle-free nasal vaccine shows promise for COVID-19

New research shows that a needle-free mucosal bacteriophage (phage) T4-based COVID-19 vaccine is effective against SARS-CoV-2 infection. The findings were published in mBio, an open access journal of the American Society for Microbiology.

In recent years, the Food and Drug Administration authorized mRNA- and adenovirus-based SARS-CoV-2 vaccines.

Scientists develop new biomimetic formulation for treating glioblastoma

Glioblastoma multiforme (GBM) is an aggressive brain cancer with a poor prognosis and few treatment options. New and effective approaches for GBM treatment are therefore urgently needed.

Based on observation of elevated lactate in resected GBM, researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences and Shenzhen Second People's Hospital have developed a

SARS-CoV-2 hijacks nanotubes between neurons to infect them

COVID-19 often leads to neurological symptoms, such as a loss of taste or smell, or cognitive impairments (including memory loss and concentration difficulties), both during the acute phase of the disease and over the long term with "long COVID" syndrome. But the way in which the infection reaches the brain was previously unknown. Scientists from Institut Pasteur and CNRS laboratories have used state-of-the-art electron microscopy approaches to demonstrate that SARS-CoV-2 hijacks nanotubes, tiny bridges that link infected cells with neurons.

Demonstration of a potent, universal coronavirus monoclonal antibody therapy for all COVID-19 variants

The SARS-CoV-2 that causes COVID-19 has killed 6.3 million people worldwide since 2019, painfully highlighting the vulnerability of humanity to novel coronaviruses.

Researchers discovered a neutralizing monoclonal antibody that potentially acts as a potent universal coronavirus therapy against SARS-CoV-2 and all its variants of concern, including Beta, Gamma, Delta, Epsilon and Omicron.

Anti-inflammatory compound shows potential in treating patients with severe COVID-19

An anti-inflammatory compound may have the potential to treat systemic inflammation and brain injury in patients with severe COVID-19 and significantly reduce their chances of death, according to a new study from UTHealth Houston and other institutions.
