Study: Age-related changes in brain stem cells are more pronounced in male animals

Ageing and age-related brain disease do not affect women and men in the same way. The adult brain constantly generates new brain cells called neurons from stem cells, a process called neurogenesis. This process is important for learning and cognitive function which declines as the brain ages.

Oxford-AstraZeneca COVID vaccine induces cell spikes similar to SARS-CoV-2's

Scientists from the University of Oxford and the University of Southampton report in the journal ACS Central Science that cells infected with the ChAdOx1 vaccine produce spike proteins on the cells similar to those produced by natural SARS-CoV-2 infection.

Accelerated cellular aging in depressed individuals associated with increased mortality risk

Cells from healthy individuals with major depressive disorder were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study by a multidisciplinary team of Walter Reed Army Institute of Research and University of California San Francisco scientists, in collaboration with others.

Study offers a promising blood test for depression, bipolar disorder

Worldwide, 1 in 4 people will suffer from a depressive episode in their lifetime. While current diagnosis and treatment approaches are largely trial and error, a breakthrough study by Indiana University School of Medicine researchers sheds new light on the biological basis of mood disorders, and offers a promising blood test aimed at a precision medicine approach to treatment.

Novel mRNA delivery system produces a therapeutic protein that protects neurons from ischemia

A lack of oxygen to brain tissue--known as ischemia--leads to the death of neurons, which results in stroke. Despite considerable research, there are currently no treatments that successfully prevent neuronal death.

Autoantibodies may contribute to severe COVID-19 and potential long-COVID-19 symptoms

New research in the USA and China. investigated how autoantibodies could mediate NETs during a COVID-19 infection. Extensive damage to the body from neutrophil extracellular traps (NETs) after infection may be contributing to thromboinflammation and the symptoms experienced by COVID-19 ‘long-haulers’.
