How regulatory T cells halt aberrant, self-reactive T cells

New research findings show in detail how self-reactive T cells—white blood cells that mistakenly attack healthy instead of infected cells, thereby causing an autoimmune or an inflammatory response—are held in check by ...

Protein movement reveals brain tumor's weak spot

Proteins do not have a single shape, but are more like dynamic robots. But—how do they actually move? And what does this tell us about their function? Laura Orellana describes the movement of proteins using computer simulations—and ...

Taming overactive molecular signaling in renal cell cancer

In a new study from the Johns Hopkins Kimmel Cancer Center, researchers described a novel mechanism of tumor formation in kidney cancers driven by overexpression of the mechanistic target of rapamycin complex 1 (mTORC1) signaling ...

A stem cell protein facilitates relapse of pediatric brain tumors

Medulloblastoma is the most common form of malignant brain tumor in children, which often can be cured with operation, radiation and chemotherapy. But a distinct type of medulloblastoma has an increased risk of becoming resistant ...

Overcoming resistance to colon cancer treatment

Colorectal cancer is one of the most common cancers. Its treatment is mainly based on chemotherapy. However, over time, chemotherapy induces resistance in the majority of patients, who end up being unresponsive to the drugs. ...

Study explains why adults' hearts don't regenerate

As heart cells mature in mice, the number of communication pathways called nuclear pores dramatically decreases, according to new research from University of Pittsburgh and UPMC scientists. While this might protect the organ ...
