In order to effectively address intractable challenges like cancer, researchers, drug developers, and clinicians need to be able to see how a potential therapeutic works within a living system, ideally in real time. That type of vision and insight is being made possible by engineers at Rensselaer Polytechnic Institute. A new $2.5 million grant from the National Institutes of Health’s National Cancer Institute (NCI) underscores the influence of Rensselaer researchers in this area, as they continue to develop new and innovative bioimaging techniques that also harness the power of machine learning methods.

Researchers have received a $1.7 million NIH grant for a novel project that is the first to investigate how the inflammatory cytokine interleukin-1 (IL-1) influences neurotransmission through a direct action on neurons and how this action triggers behavioral changes.

Results from this work could suggest new targets for the treatment of psychopathology.

Radiation is one of the oldest and most common therapies for cancer, and typically is delivered locally, or to specific targeted sites in the body. While it has long been thought that locally-delivered radiation therapy typically does not help to shrink tumors outside the field of irradiation, new preclinical research from a team at Roswell Park Comprehensive Cancer Center suggests a strategy for significantly increasing both the local and distant, or “abscopal,” effects of radiation. Results of the study, which was led by Elizabeth Repasky, PhD, have been newly published in Nature Communications.

Researchers at the La Jolla Institute for Immunology (LJI) have written a new first draft chapter in the book of immunology. They have discovered a protective biological switch that, briefly, turns on the immune response at the first whiff of an invader—an important feature—but can also turn off potentially destructive immune rampage that may also occur. This “off” switch can protect against serious, life threatening inflammation.
