NEW YORK, May 14, 2021 /PRNewswire/ Researchers have discovered new ways in which the COVID-19 virus causes human immune cells to overreact, a deadly part of the disease.
Led by researchers from NYU Grossman School of Medicine and the Perlmutter Cancer Center at NYU Langone Health, the new study found that SARS-CoV-2, the pandemic virus, interacts with specific proteins on immune cells, causing these cells to release abnormally high levels of immune signaling proteins called cytokines (a cytokine storm ). These cytokines, in turn, cause fluid buildup in the lungs and makes it hard to breathe.

“What happened in my high school experience was a very important moment for me to change my mind about what new immigrants can do to change our lives, change our community,” Chen said.

When they arrived in this country, Tong and Chen landed in the peculiar institution of the American neighborhood urban high school, where the most vulnerable children often are concentrated together and then denied what they need to thrive. New immigrants from all over the world interact with students from marginalized groups who have their own history of oppression. At the time of the attacks, Southern had a student body of more than 800 students, which was two-thirds Black and nearly a quarter Asian, with a small but growing Latino population and a handful of white students.

Some coronavirus variants are able to dodge infection-fighting antibodies, researchers at Washington University have found.
Although the antibodies tested prevent the original virus from infecting cells, the study finds three fast-spreading variants have mutations that can help them evade these immune cells.
As these new iterations of the virus become more widespread, scientists are racing to understand the possible implications for COVID-19 vaccines and treatments.
The Washington University study highlights a troubling trend: While some antibodies remained effective, it generally took more of them to quash the new variants compared to the original virus. The results, along with a growing body of research worldwide, suggest vaccines and treatments may need to be updated in the future.
