Thymulin curbs age-related inflammation and slows breast tumors in mice

Thymulin reduced age-associated inflammatory myeloid cells and slowed breast-tumor growth in aged mice by suppressing NF-κB signaling. The peptide also restored anti-PD-L1 responsiveness in aged mouse models, while human cell and tumor data supported an age-linked inflammatory myeloid profile.

Occult hepatitis B mutations drive liver cancer growth via Akt mTOR pathway

Occult hepatitis B virus (OBI) infection presents a significant global health challenge, notoriously flying under the radar of standard viral screening while relentlessly driving the pathogenesis of hepatocellular carcinoma (HCC).

Study reveals how p53 mutations cause tumors to resist cancer immunotherapy

Immune checkpoint blockade (ICB) therapy has transformed cancer treatment, but many tumors remain resistant.

UVA researcher wins federal grant to develop tools for studying rare circulating cells

A University of Virginia School of Engineering and Applied Science faculty researcher earned a major new federal grant to develop emerging tools to work with some of the rarest circulating cells in the human body, a step toward better treatments for diseases such as cancer and infection.

Thymus hormone identified as key player in reversing age-related inflammation

Chronic, low-grade inflammation in the body-a phenomenon known as "inflammaging" because it increases with age-has been linked to many of today's leading causes of illness and death, including cancer, heart disease, metabolic conditions and neurodegenerative diseases.

Exercise oncology could unlock new therapeutic pathways against cancer

Regular exercise is associated with improved outcomes for many patients with cancer, yet those with advanced disease may be unable to participate in exercise-based interventions.

Specialized blood vessels enable effective immune defense against cancer metastases

It has long been suspected that endothelial cells, the specialized cells lining the inner walls of blood vessels, play a key role in determining how the body’s immune system responds to tumors.

Study reveals mechanism underlying HBV-induced liver inflammation

Chronic hepatitis B virus (HBV) infection remains a major cause of global liver morbidity, leading to progressive necroinflammation that often culminates in cirrhosis and hepatocellular carcinoma.

New battery-powered device detects Bundibugyo Ebola virus in thirty minutes

Professor Yasutoshi Kido of the Graduate School of Medicine, Osaka Metropolitan University (OMU), in collaboration with K.K. DNAFORM and the National Institute for Biomedical Research (INRB) of the Democratic Republic of the Congo, is developing a portable rapid diagnostic system for Ebola virus disease (EVD) caused by Bundibugyo virus (BDBV).

Targeting ZBP1 may overcome cancer immunotherapy resistance

A new Review published in the open-access journal Ferroptosis and Oxidative Stress highlights Z-nucleic acid-binding protein 1 (ZBP1) as an emerging innate immune sensor that converts genomic stress into potent antitumor immunity.

Specialized dendritic cells found to coordinate antitumor immunity

Researchers at the Icahn School of Medicine at Mount Sinai have identified the immune cell that acts as the architect and coordinator of powerful immune hubs that form inside tumors and plays a key role in antitumor immunity.

Fractional COVID booster doses provide strong long-lasting immunity

Smaller doses of COVID-19 booster vaccines can provide long-lasting immunity, helping to reduce costs and improve access to vaccination, according to new research. And the findings could also inform vaccine dosing and options during future pandemics.
