Detecting trace amounts of multiple classes of antibiotics in foods

Widespread use of antibiotics in human healthcare and livestock husbandry has led to trace amounts of the drugs ending up in food products. Long-term consumption could cause health problems, but it’s been difficult to analyze more than a few antibiotics at a time because they have different chemical properties. Now, researchers reporting in ACS’ Journal […]

(January 25, 2021) – Immediately after a traumatic brain injury and as long as one year later, there are increased levels of immune cells called ILCs in the brain promoting inflammation, which can worsen brain damage, scientists report. […]

Rhesus macaques develop promising immune response to SARS-CoV-2

In a promising result for the success of vaccines against COVID-19, rhesus macaque monkeys infected with the human coronavirus SARS-CoV-2 developed protective immune responses that might be reproduced with a vaccine. The work was carried out at the California National Primate Research Center at the University of California, Davis and is published Jan. 22 in […]

Immune cells discovered in the lungs improve virus defense

A research team at the University of Basel has discovered immune cells resident in the lungs that persist long after a bout of flu. Experiments with mice have shown that these helper cells improve the immune response to reinfection by a different strain of the flu virus. The discovery could yield approaches to developing longer-lasting […]

Hydroxychloroquine blood levels predict clotting risk in patients with lupus

The antimalarial drug hydroxychloroquine is frequently prescribed to treat symptoms of the autoimmune disease lupus. In addition to decreasing disease flares, the drug can also prevent blood clots, which are a major problem in individuals with lupus. A new study in Arthritis & Rheumatology shows that monitoring patients’ blood levels of hydroxychloroquine can predict their […]

Study explains why patients with cancer spread to the liver have worse outcomes

Not only that, but transformative immunotherapy […]

Gut cells sound the alarm when parasites invade

To effectively combat an infection, the body first has to sense it’s been invaded, then the affected tissue must send out signals to corral resources to fight the intruder. Knowing more about these early stages of pathogen recognition and response may provide scientists with crucial clues when it comes to preventing infections or treating inflammatory […]

Allergists offer reassurance regarding potential allergic reactions to COVID-19 vaccines

BOSTON – Reports of possible allergic reactions to the COVID-19 vaccines produced by Pfizer-BioNTech and Moderna, both recently approved for emergency use by the U.S. Food and Drug Administration (FDA), have raised public concern. A team of experts led by allergists at Massachusetts General Hospital (MGH) has now examined all relevant information to offer reassurance […]
