The Immune System – News and Features

Researchers have identified a small molecule that can selectively block cell death. The findings lay the groundwork for next-generation neuroprotective drugs for degenerative conditions, which currently have no cure or treatments.

Researcher have discovered that the parasite Entamoeba histolytica bites into human cells and co-opts their proteins as a disguise from the immune system.

An international study of 46 mammal species shows that larger brains and a more complex immune system are linked to longer lifespans. Researchers found gene family expansions in immune-related genes among long-lived animals.

Researchers have employed a cross-species immunological analysis to provide new insights into a smallpox vaccine's immunogenicity and safety against the monkeypox virus.

A team of researchers from Moffitt Cancer Center has found new insight into why some lung cancer patients do not benefit from tumor-infiltrating lymphocyte, or TIL therapy.

Scientists have engineered a monoclonal antibody that can protect mice from a lethal dose of influenza A, a new study shows. The protective effect was enhanced by delivering the antibody in a nasal spray.

New research shows that the gum disease bacterium P. gingivalis can slip into the bloodstream and infiltrate the heart. There, it quietly drives scar tissue buildup, disrupting electrical signals and raising the risk of atrial fibrillation.

A key enzyme and its molecular pathway are critical to keeping activated CD8+ T cells active and away from “exhaustion”, offering an avenue to bolster the immune response to viruses and cancer.

Scientists are calling for clinical trials to test the potential of HIV drugs called NRTIs to prevent Alzheimer’s disease after discovering that patients taking the drugs are substantially less likely to develop the condition.

New research led by Irish scientists has uncovered how lipid-rich fluid in the abdomen, known as ascites, plays a central role in weakening the body’s immune response in advanced ovarian cancer.
