The IRP community is profoundly saddened by the recent passing of Joost “Joe” Oppenheim, M.D., Senior Investigator and Head of the Cellular Immunology Section in the Cancer Innovation Laboratory at NIH's National Cancer Institute (NCI). He died on May 14, 2022, at the age of 87.
Dr. Oppenheim was engaged in cellular immunology research at NIH for five decades and was instrumental in the discovery of cytokines, chemokines, and alarmins, which are substances produced by immune cells that enable them to communicate and act as 'first responders' to injury or infection.
Mouse Study Suggests Approach to Combat Patients’ Debilitating Tiredness

The human body is like any delicate ecosystem — disrupting just one part of it can have unexpected, widespread repercussions. Cancer patients know this well, not just because a tumor confined to one organ can cause a range of symptoms, but also because radiation treatment aimed specifically at the tumor sometimes leaves patients feeling utterly exhausted. New IRP research suggests that an inflammatory response to targeted radiation therapy is responsible for this common side effect of the treatment.
Findings Point to Approaches for Staving Off Health Problems in Infected Individuals

Over the four decades since it mysteriously began destroying the immune systems of Americans in New York and California, HIV has proven to be a frustratingly wily opponent for scientists. Even today, when treatments can fully suppress the virus in infected individuals, it continues to harm their health. A new IRP study has identified several ways dormant HIV might chronically stimulate the immune system, suggesting potential avenues for preventing the health problems that causes.
Experimental Treatment Curbs Autoimmune Eye Disease in Mice

Our cells produce a wide range of chemicals necessary for good health, but when they cannot manufacture enough of these substances, scientists can use cells cultivated in their labs to pick up the slack. In a promising example of this approach, IRP scientists stimulated lab-grown immune cells to produce tiny bundles of an important anti-inflammatory molecule and used those packages to successfully treat a potentially blinding autoimmune disease in mice.
IRP Investigators Begin Hundreds of New Coronavirus-Related Studies

Within just a few months after COVID-19 began spreading in the United States, IRP researchers had already made numerous important contributions to the fight against the deadly virus. Scientific knowledge about the disease continues to expand at a unprecedented pace, and the IRP will continue to play a major role in this effort over the coming months and years. In fact, nearly 300 new intramural research projects related to the novel coronavirus are currently starting up or have already begun.
Cells From Bone Marrow Calm Damaging Immune Response

In patients with the inflammatory disease sarcoidosis, the body’s own immune cells rampage around the body like The Incredible Hulk set loose in a city, attacking both harmful pathogens and our own tissues. However, just like the Black Widow can calm The Hulk down and return him to human form in the Avengers films, cells isolated from our bone marrow may be able to change certain immune cells from a damaging state to a benign one, according to new IRP research.

Between fast-food outlets, vending machines, and food trucks — not to mention good old-fashioned home cooking — many people face no shortage of opportunities to eat. But as satisfying as a crisp potato chip or a moist pork chop may be, people with asthma and many other conditions may prefer to resist tasty temptations if it means alleviating some of their symptoms. In a small pilot study, IRP researchers found evidence that abstaining from food for 24 hours could inhibit some of the cellular processes that cause asthmatics’ breathing problems.

The most important step to solving any problem is to choose the right tool for the job. Just like a heavy fur coat will keep you comfortable in the Arctic but slowly roast you in the Sahara, your immune system’s response can be helpful or harmful depending on the specific invader it’s fighting off. A new IRP study has identified a molecular “switch” that shifts an important type of immune cell between two different approaches to protecting the body.

In the midst of the 1957 Asian flu pandemic, doctors and researchers were understandably focused on treating patients and developing ways to contain the outbreak. It wasn’t until 30 years later that scientists began reporting that women who were pregnant when they caught the virus were more likely to have children who would later be diagnosed with schizophrenia.1 While that relationship remains controversial,2 numerous studies have since linked activation of a pregnant woman’s immune system with an increased risk that her child will develop certain psychiatric disorders, including not just schizophrenia but also autism spectrum disorder and major depressive disorder.3 A new IRP study has now expanded on this work by showing that exposure to higher levels of two immune system molecules in utero can noticeably alter the neurological and cognitive development of young children.4
