‘Immune imprinting’ by different SARS-CoV-2 spike sequences from variants, vaccines means we now have diverse patterns

New research shows that the first SARS-CoV-2 spike protein a person encounters, be it by vaccination or infection, shapes their subsequent immune response against current and future variants. That is, it imparts different properties that have an impact on the immune system’s ability to protect against variants, and also affects the rate of decay of […]

Magnetic resonance imaging and artificial intelligence can detect early signs of tumor cell death after novel therapy

In a recent study published in Nature Biomedical Engineering, a team led by researchers at Massachusetts General Hospital (MGH) has demonstrated that magnetic resonance imaging (MRI) and artificial intelligence (AI) can be used to detect early signs of tumor cell death in response to a novel virus-based cancer therapy. Recently, a promising therapeutic virus that […]
