The Immune System – News and Features

News

Existing Drug Could Reduce the Risk of Kidney Cancer Returning

Research shows that using pembrolizumab at an earlier stage of kidney cancer could reduce the risk of cancer recurring by a third.
News

Stem Cells Can Use Same Method as Plants and Insects To Protect Against Viruses

Researchers at the Francis Crick Institute have found a vital mechanism, previously thought to have disappeared as mammals evolved, that helps protect mammalian stem cells from RNA viruses such as SARS-CoV-2 and Zika virus. The scientists suggest this could one day be exploited in the development of new antiviral treatments.
News

Bacterial Metabolites Can Boost the Effectiveness of Tumor Therapies

Scientists have demonstrated that bacterial metabolites can increase the cytotoxic activity of certain immune cells and thus positively influence the efficiency of tumor therapies.
News

Dying Cells Protect Their Neighbors To Maintain Tissue Integrity

To enable tissue renewal, human tissues constantly eliminate millions of cells, without jeopardizing tissue integrity, form and connectivity. Scientists have revealed a new process which allows eliminated cells to temporarily protect their neighbors from cell death, thereby maintaining tissue integrity.
News

Exact Mechanism of Vaccine-Induced Blood Disorders Identified

A McMaster University team of researchers recently discovered how, exactly, the COVID-19 vaccines that use adenovirus vectors trigger a rare but sometimes fatal blood clotting reaction called vaccine-induced immune thrombotic thrombocytopenia or VITT.
News

"Zombie Cells" Give Clues to Spinal Cord Injury Repair

Mammals have a poor ability to recover after a spinal cord injury. A main reason for this is the formation of a scar that blocks tissue repair. Now, researchers have shown that the administration of drugs that target specific cellular components of this scar improve functional recovery after injury.
News

Are Biomaterial Vaccines on the Horizon?

Researchers have developed a biomaterial-based infection vaccine (ciVAX) that can reprogram the immune system to take action against pathogens.
News

Genes Shape Gut Microbiomes More Than We Thought

Most studies show that our gut microbiome is primarily affected by our lifestyle, including what we eat or the medications we take, but a new study has found a much greater genetic component at play.

News

Repeated Ketamine Anesthesia Restarts Plasticity in the Brain

Researchers have discovered two methods to restart plasticity in the brain, repeated ketamine anesthesia and non-invasive light flickering.
News

Tuning the Immune System May Enhance Vaccines

Immunologists have identified a biological pathway that selectively controls how T follicular helper cells mature into functional components of the immune system.
