By discovering a trick the hepatitis C virus uses to evade the immune system, scientists have identified a new antiviral defense system that could be used to...
by Rockefeller University Press A phase I/II clinical trial by researchers at Stanford University suggests that vaccines prepared from a patient’s own tumor cells may prevent the incurable blood cancer mantle cell lymphoma (MCL) from returning after treatment. The study, which will be published June 19 in the Journal of Experimental Medicine (JEM), reveals that...
Berkeley Lovelace Jr. @BERKELEYJR Coronavirus antibodies may last only two to three months after a person becomes infected with Covid-19, according to a new study published Thursday in Nature Medicine. Researchers in the Wanzhou District of China compared the antibody response of 37 asymptomatic people with that of 37 symptomatic people. The researchers found people...
o defend the body, the immune system makes proteins known as antibodies that latch onto the perceived threat, be it HIV, the new coronavirus or, as is the case in autoimmune disease, part of the body itself. In a new proof-of-concept study in ACS Sensors, researchers describe a new system for detecting antibodies within a...
by Johannes Angerer, Medical University of Vienna A MedUni Vienna study group has identified a previously unknown mechanism involved in the development of intestinal cancer: The bacterial microbiome activates the so-called immune checkpoint Ido1 in Paneth cells, a special cell that is only found in the gastrointestinal tract, thereby preventing local intestinal inflammation. However, this...
Chemical found in apple peel could transform multiple sclerosis treatment Compound could be turned into the first drug that reverses disease’s damage Testing on mice, paralysed animals given ursolic acid were able to walk again A chemical in apple peel could transform the treatment of multiple sclerosis, research reveals. The compound that gives apple skin...
by National Cancer Institute Scientists have developed a new test that can help identify people who are likely to develop hepatocellular carcinoma (HCC), the most common form of liver cancer. The approach uses a simple blood test to check for the patient’s previous exposure to certain viruses. A study of the new approach was led...
by Cincinnati Children’s Hospital Medical Center A microscopic photo of a blood smear from a transgenic mouse that mimics the human immune disorder, secondary HLH (hemophagocytic lymphohistiocytosis). The image shows macrophage immune cells (indicated by arrow) flooding healthy tissue cells during a cytokine storm caused by HLH in a very similar fashion t what occurs...
By Ben Coxworth May 26, 2020 One of the creepy things about ticks is the fact that not only do they suck your blood, but they’re able to do so for a long time, undetected. Scientists have now synthesized the protein that lets them get away with it, and it may have life-saving medical applications....
According to a BBC report, the UK has authorized the use of the anti-viral drug Remdesivir in treating patients with the novel coronavirus as experts have discovered that the drug could shorten the recovery time of infected individuals. At last a breakthrough! Looking forward to discussing use of #REMDESIVIR against #COVID__19 with @mrdanwalker & #louiseminchin...
