Igor Stagljar made his career building molecular tools to combat cancer. But when the pandemic hit last March, he aimed his expertise at a new adversary, SARS-CoV-2.
Most people with cancer who are infected by the novel coronavirus produce antibodies at a rate comparable to the rest of the population—but their ability to do so depends on their type of cancer and the treatments they’ve received, according to a new study by researchers at Montefiore Health System and Albert Einstein College of Medicine. The findings, published online today in Nature Cancer, may lead to better care for cancer patients, who face a heightened risk of dying from COVID-19, and suggests that cancer patients should respond well to COVID-19 vaccines.
A new research study at the University of Chicago Medicine has found that when it comes to COVID-19, having vitamin D levels above those traditionally considered sufficient may lower the risk of infection, especially for Black people.
Research from the University of Kent's School of Biosciences has revealed that a molecule produced by the human immune system can severely diminish the potency of certain antibiotics.

Dr. Saphire will become La Jolla Institute’s fifth president when she formally begins her term on September 1, 2021. She will succeed current LJI President Mitchell Kronenberg, who has successfully led the organization for the past 18 years.
Research reveals how mutated SARS-CoV-2 evades immune system defenses In lab-dish experiments, the mutant virus escaped antibodies from the plasma of COVID-19 survivors as well as pharmaceutical-grade antibodies Mutations arose in an immunocompromised patient with chronic SARS-CoV-2 infection Patient-derived virus harbored structural changes now seen cropping up independently in samples across the globe Findings underscore the need for better genomic surveillance to keep track of emerging variants Results highlight importance of therapies aimed at multiple targets on SARS-CoV-2 to minimize risk of resistance

Scientists at Washington University School of Medicine in St. Louis have implicated a type of immune cell in the development of chronic lung disease that sometimes is triggered following a respiratory viral infection. The evidence suggests that activation of this immune cell serves as an early switch that, when activated, drives progressive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD).
The body's immune response plays a crucial role in the course of a SARS-CoV-2 infection.

By analyzing blood samples from individuals infected with SARS-CoV-2, researchers in Singapore have begun to unpack the different responses by the body’s T cells that determine whether or not an individual develops COVID-19. The study, published today in the Journal of Experimental Medicine (JEM), suggests that clearing the virus without developing symptoms requires T cells to mount an efficient immune response that produces a careful balance of pro- and anti-inflammatory molecules.
Discovery of a metabolic pathways that inhibit memory T cell production has potential for enhancing the immune system’s ability to fight infections and cancers.
Medical researchers have long understood that a pregnant mother’s diet has a profound impact on her developing fetus’s immune system and that babies — especially those born prematurely — who are fed breast milk have a more robust ability to fight disease, suggesting that even after childbirth, a mother’s diet matters. However, the biological mechanisms underlying these connections have remained unclear.

Scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study, published in Nature, also shows that movement-induced stimulation is required for the maintenance of this niche, as well as the bone and immune-forming cells that it contains. Together, these findings identify a new way that exercise strengthens bones and immune function.

Researchers at Washington University School of Medicine in St. Louis have identified a potential way to eradicate the latent HIV infection that lies dormant inside infected immune cells. Studying human immune cells, the researchers showed that such cells have a natural alarm system that detects the activity of a specific HIV protein. Rather than attack the virus based on appearance, this strategy is to attack the virus based on what it is doing — vital activities that are required for the virus to exist.
It is necessary to develop additional COVID-19 vaccines, as different vaccine approaches have their advantages and disadvantages and may work synergistically.

Scientists are hoping advances in cancer research could lead to a day when a patient's own immune system could be used to fight and destroy a wide range of tumors. Cancer immunotherapy has some remarkable successes, but its effectiveness has been limited to a relatively small handful of cancers. In APL Bioengineering, researchers describe how advances in engineering models of tumors can greatly expand cancer immunotherapy's effectiveness to a wider range of cancers.
