Researchers discover molecule that provides dual protection against vascular inflammation


Researchers discover molecule that provides dual protection against vascular inflammation
A multidisciplinary team of researchers from Duke-NUS Medical School and the Agency for Science, Technology and Research (A STAR) in Singapore discovered a new mitochondrial peptide called MOCCI that plays an important role in regulating inflammation of blood vessel and immunity. The study, published in the journal
Nature Communications, revealed how one gene encoded two molecules that provide two-pronged protection following viral infection.
Chronic and excessive inflammation of the blood vessels, known as vascular inflammation, can lead to tissue damage and cardiovascular diseases such as atherosclerosis and fibrosis. Although some therapies have shown promising results in clinical trials, they have considerable side effects, such as immunosuppression leading to increased risk of infection, and limited efficacy. Therefore, more effective treatments are urgently needed. ....

Strong and balanced T cell response: key to controlling SARS-CoV-2 infection without getting COVID-19


 E-Mail
To effectively fight off SARS-CoV-2, the immune system depends on both antibodies and T cells, a type of white blood cell, which work together to eradicate the virus. However, little was known about virus-specific T cells in asymptomatic patients.
We now know that many people are getting infected with SARS-CoV-2 without realising it, as they stay healthy and don t develop any symptoms. These asymptomatic infections may provide the key to understanding how the immune system can control the virus without triggering pathological processes, explained Dr Nina Le Bert, Senior Research Fellow at the Duke-NUS Emerging Infectious Diseases (EID) Programme and the co-author of this study. ....

A brain enzyme plays an important role in waking up neural stem cells


A brain enzyme plays an important role in waking up neural stem cells
Researchers studying an enzyme in fruit fly larvae have found that it plays an important role in waking up brain stem cells from their dormant quiescent state, enabling them to proliferate and generate new neurons. Published in the journal EMBO Reports, the study by Duke-NUS Medical School, Singapore, could help clarify how some neurodevelopmental disorders such as autism and microcephaly occur.
Quiescent neural stem cells in the fruit fly larval brainPr-set7 is an enzyme involved in maintaining genome stability, DNA repair and cell cycle regulation, as well as turning various genes on or off. This protein, which goes by a few different names, has remained largely unchanged as species have evolved. Professor Wang Hongyan, a professor and deputy director at Duke-NUS Neuroscience and Behavioural Disorders Programme, and her colleagues set out to understand the protein s function during brain development ....
