Sugar molecules as a target in cancer therapy

Cancer cells use sugar molecules on their surface to disable attacks by the body's immune system. Researchers at the University of Basel now report on how this mechanism can be neutralized.

The immune system is actually extremely well equipped to get rid of abnormal cells.

Study reveals vaccine confidence declined considerably during COVID-19 pandemic

A new study suggests that, despite the success of the COVID-19 vaccination campaigns, vaccine confidence has declined significantly since the start of the pandemic.

Researchers from the University of Portsmouth carried out two anonymous surveys in the winters of 2019 and 2022 to investigate people's attitudes towards vaccinations and the factors that might underpin hesitancy and refusal.

New insights on antibody responses to Omicron variants

Knowing how well vaccination against one SARS-CoV-2 strain (with or without previous infection) counteracts infection with a different strain is a critical research question. The answers could guide strategies to continue to subdue the COVID pandemic, even as the coronavirus regains ground.

The origin-of-life molecule, a key to cancer research

RNA, the molecule that gave rise to life, has been shown to be essential for repairing human genetic material and preventing mutations that might lead to developing cancer. Recent advances in research, such as those published by the research team of Daniel Gómez Cabello at the University of Seville, propose this compound as a therapeutic target for developing tailored strategies for treating cancer.

Ancient viral DNA in human genome guards against infections

Viral DNA in human genomes, embedded there from ancient infections, serve as antivirals that protect human cells against certain present-day viruses, according to new research.

The paper, "Evolution and Antiviral Activity of a Human Protein of Retroviral Origin," published in Science, provides proof of principle of this effect.

Fighting tumors with magnetic bacteria

Scientists around the world are researching how anti-cancer drugs can most efficiently reach the tumours they target. One possibility is to use modified bacteria as "ferries" to carry the drugs through the bloodstream to the tumours. Researchers at ETH Zurich have now succeeded in controlling certain bacteria so that they can effectively cross the blood vessel wall and infiltrate tumour tissue.

Novel derivative of "love hormone" oxytocin improves cognitive impairment in Alzheimer's

The cognitive decline and memory loss observed in Alzheimer's disease (AD) is attributed to the accumulation of β-amyloid protein (Aβ), which impairs neural function in the brain. Experimentation has shown that oxytocin, a peptide hormone primarily responsible for parturition, bonding, and lactation, also regulates cognitive behavior in the rodent central nervous system (CNS).
