The “Greying” of T Cells

Harvard Medical School

Research in mouse cells identifies defective metabolic pathway in aging immune T cells. The pathway is critical for switching T cells from dormancy into illness-fighting mode. In experiments, researchers restored lagging T-cell function by adding small-molecule compounds. Findings suggest possible mechanism behind weakened immunity common in the elderly.

Humans may be reversing the climate clock, by 50 million years

University of Wisconsin-Madison

Our future on Earth may also be our past. In a study published Monday (Dec. 10, 2018) in the Proceedings of the National Academy of Sciences, researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years. And it’s taken just two centuries.

Regrowing damaged nerves hinges on shutting down key genes

Washington University in St. Louis

Neurons in the brain and spinal cord don’t grow back after injury, unlike those in the rest of the body. Now, researchers at Washington University School of Medicine in St. Louis have identified some of the key steps taken by nerves in the legs as they regenerate. The findings lay out a path that spinal cord neurons might be able to follow – potentially leading to improved recovery for people paralyzed by spinal cord injuries.

Researchers Develop Accurate, Non-Invasive Method to Detect Bladder Cancer

Tufts University

A research team has developed a non-invasive method for detecting bladder cancer that might make screening easier and more accurate than current invasive clinical tests involving visual inspection of bladder. In the first successful use of atomic force microscopy (AFM) for clinical diagnostic purposes, the researchers have been able to identify signature features of cancerous cells found in patients’ urine by developing a nanoscale resolution map of the cells’ surface.

Researchers Alleviate Schizophrenia Symptoms in New Mouse Models

Case Western Reserve University

In a recent issue of the Proceedings of the National Academy of Sciences, Lin Mei, MD, PhD, asked, does all the tinkering in young mice hamper their brain development, causing schizophrenia-like symptoms? Or, do their brain cells develop normally, but in adulthood struggle to communicate? Researchers need to know whether to focus their efforts on brain cell development or communication, or both, because the answer to these questions implies different therapeutic approaches.
