Salk scientists discover that central nervous system-resident immune cells called microglia use TAM receptors (discovered by study senior author Greg Lemke in 1991) to eat specific nerve cells in mouse model of ALS. The study is the first to show TAM receptors can be used to kill living nerve cells, and the findings contribute to ongoing efforts to harness TAM receptors in clinical settings to treat cancers, autoimmune disorders, and more.
Many cases of melanoma are treated with PD-1 blockade immunotherapy – a treatment that unleashes the body’s own immune system against cancer – which has demonstrated transformative results.
However, most melanoma patients treated with this immunotherapy eventually relapse. Understanding why has been one of the most pressing questions in cancer medicine.
UC Irvine researchers built a mathematical model of tumor immune activity to pinpoint a key cause of relapse: the rate at which PD-1 blockade immunotherapy activates regulatory T cells that infiltrate the tumor and suppress the tumor-killing response of the immune system. The team confirmed this math-driven prediction experimentally.
The findings point toward a promising new strategy: pairing PD-1 blockade immunotherapy with more targeted treatments that prevent immunosuppressive regulatory T cells from reaching the tumor. The model also provides a framework for testing other treatment combinations, offering a fast, cost-effective path to better therapies.
People who take part in screening for colorectal cancer may have as much as 43 per cent lower risk of dying from the disease, according to new estimates published in JAMA Network Open by researchers at Karolinska Institutet and Umeå University in Sweden. These findings are based on up to 14 years of follow-up data from the Stockholm–Gotland screening programme.
Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.
A comparative study of the cancer clinical trial portfolios supported by federal funding versus industry funding reveals they have distinct, interdependent roles – both vital – in cancer research. The work, “Federal and Industry Sponsorship in US Cancer Clinical Trials,” is published online August 20th by JAMA Oncology.
