High levels of ammonia in colon tumors inhibits T cell growth and response to immunotherapy

High levels of ammonia in tumors leads to fewer T cells and immunotherapy resistance in mouse models of colorectal cancer, new findings from the University of Michigan Rogel Cancer Center revealed. Researchers found that ammonia inhibits the growth and function of T cells, which are vital for anti-tumor immunity. The findings appear in Cell Metabolism.

COVID-19 booster increases durability of antibody response, research shows

New research from the University of Virginia School of Medicine speaks to the benefits of a COVID-19 booster.

The new findings shed light on how mRNA boosters - both Pfizer and Moderna - affect the durability of our antibodies to COVID-19. A booster, the researchers report, made for longer-lasting antibodies for all recipients, even those who have recovered from a COVID-19 infection.

Artificial DNA kills cancer

Researchers at the University of Tokyo have used artificial DNA to target and kill cancer cells in a completely new way. The method was effective in lab tests against human cervical cancer- and breast cancer-derived cells, and against malignant melanoma cells from mice. The team created a pair of chemically synthesized, hairpin-shaped, cancer-killing DNA.

Large, real-world study finds COVID-19 vaccination more effective than natural immunity

In one of the first large, real-world studies comparing the effectiveness of COVID-19 vaccines versus natural immunity in protecting against death, hospitalizations and emergency department (ED) visits for any cause, including COVID, research-scientists from Regenstrief Institute, Indiana University School of Medicine and Vanderbilt University Medical Center report that people of all age groups benefited significantly more from vaccination than natural immunity acquired from a previous COVID infection.

Killing pancreatic cancer with T cells that supercharge themselves

Scientists at UC San Francisco (UCSF) have engineered T cells to produce a potent anti-cancer cytokine, but only when they encounter tumor cells. The immunotherapy eliminated melanoma and pancreatic cancer in mice without major side effects, and it offers a promising new strategy for fighting these and other hard-to-treat cancers.

Drug discovery offers potential treatment for common kidney disease

A serious condition that can cause the kidneys to suddenly stop working could be treated with existing medicines, a new study shows.

In a study in mice scientists found that medicines usually used to treat angina and high blood pressure prevented much of the long-term damage to the kidney and cardiovascular system caused by acute kidney injury (AKI).

Expanding the arsenal of drugs against COVID-19

The ongoing COVID-19 pandemic, caused by the SARS-CoV-2 virus, has been devastating the entire world. While the vaccination program is advancing, drug treatments for COVID-19 are still highly important for those who become infected. Now, a team at Tokyo Medical and Dental University (TMDU), National Center for Global Health and Medicine (NCGM), Tohoku University, NCI/NIH, and Kumamoto University has designed and synthesized compounds that have the potential to be novel drugs targeting SARS-CoV-2.
