A closer look at T cells reveals big differences in mild vs. severe COVID-19 cases

A big question on people’s minds these days: how long does immunity to SARS-CoV-2 last following infection?

Now a research team from La Jolla Institute for Immunology (LJI), The University of Liverpool and the University of Southampton has uncovered an interesting clue. Their new study suggests that people with severe COVID-19 cases may be left with more of the protective “memory” T cells needed to fight reinfection.

Weizmann Institute of Science and Colleagues Show How Cancer Cells Hurt Themselves to Hurt Immune Cells More

Melanoma is skilled at evading therapies, with its cells going so far as to starve in order to stop the immune cells that would eradicate them. A team from the Weizmann Institute, including Prof. Yardena Samuels; the Netherlands Cancer Institute; and the University of Oslo have revealed one of melanoma’s tricks – never before seen in human cells – and a therapeutic target.

T cells can shift from helping to harming in atherosclerosis

At La Jolla Institute for Immunology (LJI) researchers are dedicated to finding a way to stop plaques from forming in the first place. In a new study, LJI scientists show that certain T lymphocytes, a type of white blood cell, that start out trying to fight the disease can end up increasing inflammation and making atherosclerosis cases even worse.

Even in the worst COVID-19 cases, the body launches immune cells to fight back

SHAREInternational collaboration provides important piece of COVID-19 puzzleLA JOLLA—A new study from researchers at La Jolla Institute for Immunology (LJI) and Erasmus University Medical Center (Erasmus MC) shows that even the sickest COVID-19 patients produce T cells that help fight the virus. The study offers further evidence that a COVID-19 vaccine will need to elicit T cells to work alongside antibodies.
