The Immune System
-
Aspirin, taken by around 29 million Americans daily, has increasingly been linked to inhibiting the growth of certain cancers – but we didn't quite know how. Now, scientists have uncovered how it helps the immune system see and kill cancer cells.
-
A single-shot vaccine that protects against multiple coronaviruses, including the one that causes COVID-19, has been developed. It erased all viral traces from the lungs of animal subjects, opening a pathway for a similar human vaccine.
-
A man that police caught taking 217 doses of COVID vaccine has offered himself up to researchers for a study looking into what happens to the immune system after so many doses. The results offer surprising insight into these new mRNA vaccines.
-
Ever since SARS-CoV-2 emerged, the virus has been known for its novel effects on the brain. But exactly how is it causing these symptoms? A new study suggests that the answer lies in the way our vagus nerve talks to the brain.
-
Researchers have discovered a never-before-identified type of memory B cell, an immune cell that ‘remembers’ what a person is allergic to, potentially opening the door to new therapeutics to treat allergies, including life-threatening food allergies.
-
Researchers found that getting a multidose vaccine in different arms may improve the body’s immune response to the vaccine by up to four-fold. While they exclusively looked at the COVID-19 vaccine, they suspect this effect may be seen with others.
-
A new study may explain the variable severity of SARS-CoV-2 from person to person. Using AI-driven machine-learning researchers discovered the virus is broken down into fragments, and this debris resembles peptides that overstimulate the immune system.
-
White blood cell numbers can be cut by health conditions or treatments like chemotherapy. Yale scientists have now discovered a molecule that can be given to quickly boost their numbers back up, to help fight off infections without antibiotics.
-
Researchers have identified a blood protein ‘signature’ in the complement system, part of the immune system, of patients with long COVID that may improve the diagnosis and lead to a treatment for the debilitating condition.
-
A new form of immunotherapy helps immune cells “armor” themselves against exhaustion by releasing their own medicine to keep them going in the fight against cancer. The new method is faster and cheaper to produce than existing immunotherapies.
-
Researchers have found adding a hyperactive form of the protein Rac2 to macrophages, immune cells that eat pathogens, causes them to cannibalize T cells. The novel technique could potentially boost the effectiveness of an emerging cancer treatment.
-
Researchers have worked with biology rather than against it, fitting microparticle 'backpacks' to important inflammatory cells called macrophages to significantly reduce lesion size and inflammation caused by traumatic brain injury.
