Low doses of radiation promote cancer-capable cells

Low doses of radiation equivalent to three CT scans, which are considered safe, give cancer-capable cells a competitive advantage over normal cells in healthy tissue, scientists have discovered. Researchers at the Wellcome ...

How to equip the brake of immunity

The immune system is indispensable for defense against invading pathogens, but its aberrant activation may lead to autoimmune diseases. Regulatory T cells play a crucial role in preventing excess immune activation; mice without ...

Glowing brain cells illuminate stroke recovery research

A promising strategy for helping stroke patients recover, transplanting neural progenitor cells to restore lost functions, asks a lot of those cells. They're supposed to know how to integrate into a mature (but damaged) brain. ...

Researchers identify new way to make cancer self-destruct

For years, researchers have been trying to target a gene called MYC that is known to drive tumor growth in multiple cancer types when it is mutated or over-expressed, but hitting that target successfully has proven difficult. ...

Scientists track brain tumor turncoats with advanced imaging

Glioblastomas, the deadliest type of brain tumor in adults, attract "turncoats." These are macrophages, a type of immune cell, which promote tumor progression and mask tumors from the immune system's scrutiny. To better understand ...
