Immune cells such as T and B cells are central to the body’s defence against both infections and tumours.
Researchers at the Francis Crick Institute, working with Imperial College London, King’s College London and University of Cambridge, have shown that an influx of water and ions into immune cells allows them to migrate to where they’re needed in the body.
Researchers at the Icahn School of Medicine at Mount Sinai have identified an allergy pathway that, when blocked, unleashes antitumor immunity in mouse models of non-small cell lung cancer (NSCLC). And in an early parallel study in humans, combining immunotherapy with dupilumab—an Interleukin-4 (IL-4) receptor-blocking antibody widely used for treating allergies and asthma—boosted patients' immune systems, with one out of the six experiencing significant tumor reduction. The findings were described in the December 6 issue of Nature.

A study that assesses the effects of hypochlorous acid (HOCI), commonly known as bleach, as it is generated during the immune response of a cell (phagocytosis) when fighting a common fungal pathogen, Candida albicans, reveals that HOCI is a potent killing agent. The laboratory finding is highlighted in the journal mBio.
La inmunoterapia aprovecha el sistema inmunitario del organismo para combatir el cáncer. El tratamiento con linfocitos T con receptor quimérico para el antígeno (tratamiento con linfocitos T-CAR) es una forma de inmunoterapia en la que los profesionales de atención médica extraen las células T de una persona (conocidas como linfocitos que participan en la respuesta del sistema inmunitario) y las modifican genéticamente para que produzcan receptores quiméricos para el antígeno. A continuación, estos linfocitos T-CARse reintroducen en el torrente sanguíneo del paciente, donde se dirigen a las células cancerosas y las destruyen.

Our bodies are transversed by millions of nerve fibres that transmit information. This allows us to do things like control muscles and perceive sensory impressions. Peripheral nerves, like those in our arms and legs, are often damaged by acute injuries, for example, in accidents. As a result, those affected suffer from loss of muscle strength and sensory problems such as numbness. Peripheral nerves do have a strong regenerative potential, but complete recovery of nerve function is still rare for reasons that are not yet fully understood.
Far too many antibiotics are used around the world. As a result, bacteria are becoming resistant. Curing bacterial diseases is becoming more difficult than before, because antibiotics are perhaps our foremost weapons in the fight against them.
Messenger bubbles produced by human cells can pick up bacterial products and deliver them to other cells, University of Connecticut researchers report in the Nov. 16 issue of Nature Cell Biology.
During the nearly five decades of its operation, the European Molecular Biology Laboratory (EMBL) in Hamburg has developed many fruitful collaborations with other scientific institutions located in the Hamburg metropolitan area.
In a new Cell study, scientists at La Jolla Institute for Immunology (LJI) and Massachusetts General Hospital, Harvard Medical School, show how a protein called IKAROS helps "weave" the genome.
Researchers at Michigan State University have shown that cells known as glia could lower the threshold to trigger visceral pain in patients, such as those with irritable bowel syndrome, who have experienced inflammation in the gut. The finding was reported in the journal Science Signaling. The team discovered this phenomenon in mice, meaning the results may not completely extrapolate to humans. Still, the work provides a new avenue of exploration to better treat visceral pain, which is the most common gastrointestinal issue.
Despite advancements, cancer remains a major global health challenge, taking millions of lives every year. Traditional treatments such as chemotherapy, while effective, often have severe side effects and don't consistently guarantee a complete cure. Cancer stem cells (CSCs), recently spotlighted in scientific research, have been identified as key players behind cancer's tenacity, recurrence, and resistance to treatments.
What is the mechanism that allows our brains to incorporate new information about the world, and form memories?
Several studies have investigated the effect of parental age on biological parameters such as reproduction, lifespan, and health; however, the results have been inconclusive, largely due to inter-species variation and/or modest effect sizes.
The Wnt signaling pathway, a system present in living organisms, plays a pivotal role in cell growth, differentiation, and migration. It has a long history dating back to 1982 when the first Wnt gene, which is essential for cellular growth, was discovered.

This new genetic model is the first of its kind.
