by Annie Curtis, The Conversation Our body clock has evolved over millions of years to help us survive. Credit: kanyanat wongsa/ Shutterstock When microorganisms—such as bacteria or viruses—infect us, our immune system jumps into action. It’s highly trained to sense and eliminate infections and clear up any damage caused by them. It’s typically assumed our immune systems...

Scientists learn what fuels the ‘natural killers’ of the immune system
by Memorial Sloan Kettering Cancer Center Credit: CC0 Public Domain Despite a name straight from a Tarantino movie, natural killer (NK) cells are your allies when it comes to fighting infections and cancer. If T cells are like a team of specialist doctors in an emergency room, NK cells are the paramedics: They arrive first on...
153 years after discovery of the immune system’s dendritic cells, scientists uncover a new subset

The immune system’s B cells have the unique distinction of being the only cells in the human body that evolve, in real time—and an international team of scientists announced...
New research optimizes body’s own immune system to fight cancer
A groundbreaking study led by engineering and medical researchers at the University of Minnesota Twin Cities shows how engineered immune cells used in new cancer therapies can overcome physical barriers to allow a patient’s own immune system to fight tumors. The research could improve cancer therapies in the future for millions of people worldwide. The research is published...
Food dyes may cause disease when the immune system is dysregulated, researchers report
by The Mount Sinai Hospital Credit: Pixabay/CC0 Public Domain Artificial food colorants can cause disease when the immune system has become dysregulated, Icahn School of Medicine at Mount Sinai researchers report. The study, published in Cell Metabolism in May, was the first to show this phenomenon. The study, conducted in mice, found that the mice developed colitis when they consumed...
Gene therapy offers potential cure to children born without an immune system

How SARS-CoV-2 hijacks human cells to evade immune system
by University of California – San Diego Human enzyme METTL3 adds methyl groups to introduce m6A in SARS-CoV-2’s RNA. That modification prevents the virus’ RNA from triggering inflammatory molecules known as cytokines. METTL3 also leads to increased expression of pro-viral genes — those that encode proteins needed for SARS-CoV-2 replication and survival. Credit: University of California...
Artificial intelligence model predicts which key of the immune system opens the locks of coronavirus
by Aalto University Credit: Jani Huuhtanen, Biorender.com With an artificial intelligence (AI) method developed by researchers at Aalto University and University of Helsinki, researchers can now link immune cells to their targets and for example uncouple which white blood cells recognize SARS-CoV-2. The developed tool has broad applications in understanding the function of immune system in infections, autoimmune disorders, and...
