Pain-Sensing Neurons Kick-Start Immune Responses

Pain-sensing neurons in the gut kindle inflammatory immune responses that cause allergies and asthma, according to a new study by Weill Cornell Medicine. The findings, published Jan. 7 in Nature, suggest that current drugs may not be as effective because they only address the immune component of these conditions, overlooking the contribution of neurons.

“Today’s blockbuster biologics are sometimes only 50% effective and when the treatments do work, they sometimes lose their efficacy...

Students Break Down Big Science into Inspiring Stories

Three minutes and one slide were all it took for twelve young scientists to turn cutting-edge research into dramatic stories of hope at Weill Cornell Medicine’s tenth annual Three-Minute Thesis (3MT) competition on Nov. 13 in Uris Auditorium. The night showcased bold ideas about tackling Alzheimer’s disease, cancer, infectious diseases and more with creativity and passion.

Students from Weill Cornell Graduate School of Medical Sciences, Gerstner Sloan Kettering Graduate School of...

Improving Lives Through Academic Innovation, Commercialization and Entrepreneurship

Why are innovation and entrepreneurship important in academic research? Since the Bayh-Dole Act was passed in 1980, permitting institutions to retain ownership of their inventions arising from federal funding, more than 200 drug treatments and vaccines have been brought to market through academic-commercial partnerships.

Weill Cornell Medicine’s Ninth Annual Dean’s Symposium on Innovation and Entrepreneurship celebrated and fostered this entrepreneurial spirit on Nov. 17 at Weill...

Aging Midbrain Neurons Face Energy Crisis Linked to Parkinson’s

Dopamine neurons in a part of the brain called the midbrain may, with aging, be increasingly susceptible to a vicious spiral of decline driven by fuel shortages, according to a study led by Weill Cornell Medicine investigators. The findings offer a potential explanation for the degeneration of this neuron population in Parkinson’s disease.

In the study, published Dec. 5 in the Proceedings of the National Academy of Sciences, the scientists examined how midbrain dopamine neurons, which...

Research Matters: Personalizing Pancreatic Cancer Treatment

Video of Research Matters: Personalizing Pancreatic Cancer Treatment

It’s not surprising that pancreatic cancer is often referred to as a silent killer. With few early symptoms and an aggressive nature, it has one of the lowest survival rates of all cancers.

“By the time people are diagnosed with pancreatic cancer, most are not candidates for surgery because the tumor is too extensive,” said Dr. Despina Siolas, assistant professor of medicine at Weill Cornell Medicine and an...

New Immune Cell Suspects in Lupus

Detailed mapping of CD4⁺ T cells from children with systemic lupus erythematosus (SLE) has revealed distinct immune cell subsets with likely roles in disease pathogenesis, according to a study led by Weill Cornell Medicine investigators. The findings are poised to redirect lupus research and open the door to more precise therapies that avoid broad immune suppression.

Published Oct. 21 in Nature Immunology, the study used single-cell RNA sequencing to profile CD4⁺ T-cell subtypes from...

Early Brain Differences May Explain Sex-Specific Risks for Addiction

The roots of addiction risk may lie in how young brains function long before substance use begins, according to a new study from Weill Cornell Medicine. The investigators found that children with a family history of substance use disorder (SUD) already showed distinctive patterns of brain activity that differ between boys and girls, which may reflect separate predispositions for addiction. The research, published Nov. 21, in Nature Mental Health, analyzed brain scans from nearly 1,900...

Scientists Identify a Molecular Switch to a Painful Side Effect of Chemotherapy

Chemotherapy activates a stress sensor in immune cells, triggering inflammation and nerve damage, which may help explain why many cancer patients experience debilitating pain as a side effect, according to a new study by Weill Cornell Medicine and Wake Forest University School of Medicine researchers.

Up to half of all patients receiving chemotherapy experience chemotherapy-induced peripheral neuropathy (CIPN), which causes tingling, numbness and pain in the hands and feet. Since there...

Reviving Exhausted Immune Cells Boosts Tumor Elimination

A new study has discovered a molecular signal that tumors exploit to exhaust the T cells meant to destroy them—and how silencing that signal could revive the body’s immunity. The study led by Weill Cornell Medicine researchers was published Nov. 17 in Nature Immunology and shows that tumors not only evade the immune system but can actively reprogram immune cells to stop fighting.

“Our dream is to make immune-based therapies available to every patient. To overcome resistance, we must...

Hypertension Affects the Brain Much Earlier than Expected

Hypertension impairs blood vessels, neurons and white matter in the brain well before the condition causes a measurable rise in blood pressure, according to a new preclinical study from Weill Cornell Medicine investigators. The changes help explain why hypertension is a major risk factor for developing cognitive disorders, such as vascular cognitive impairment and Alzheimer’s disease.

The preclinical study, published Nov. 14 in Neuron, reveals that hypertension may induce early gene...
