St. Jude Children’s Research Hospital scientists, in collaboration with the Institute of Environmental Science and Research (ESR) Limited, found that immune cells present in people months before influenza (flu) infection could more accurately predict if an individual would develop symptoms than current methods which primarily rely on antibody levels. The […]

Genetically modified neural stem cells show promising therapeutic potential for spinal cord injury
A research team co-led by City University of Hong Kong (CityU) and The University of Hong Kong (HKU) has recently made a significant advancement in spinal cord injury treatment by using genetically modified human neural stem cells (hNSCs). They found that specifically modulating a gene expression to a certain level […]
AI method uses transformer models to study human cells
Researchers in Carnegie Mellon University’s School of Computer Science have developed a method that uses artificial intelligence to augment how cells are studied and could help scientists better understand and eventually treat disease. Images of organ or tissue samples contain millions of cells. And while analyzing these cells in situ […]
Genetically engineered vesicles target cancer cells more effectively
Nanovesicles can be bioengineered to target cancer cells and deliver treatments directly, according to research at Binghamton University, State University of New York. Two unfortunate facts about chemotherapy: It can harm healthy cells as well as cancerous ones, and many therapeutic targets stay within cancer cells, making them harder to […]
When regulatory T cells go bad
Scientists can finally hunt down a harmful kind of human T cell, thanks to new research led by scientists at La Jolla Institute for Immunology (LJI) and the Medical College of Georgia (MCG) at Augusta University. Immune cells called ex-T regulatory cells (exTregs) tend to be rare in the body […]
Tattoo technique transfers gold nanopatterns onto live cells
For now, cyborgs exist only in fiction, but the concept is becoming more plausible as science progresses. And now, researchers are reporting in ACS’ Nano Letters that they have developed a proof-of-concept technique to « tattoo » living cells and tissues with flexible arrays of gold nanodots and nanowires. With further refinement, […]
Bioengineered tool unmasks cancer cells
Cancer cells can evade the body’s immune defenses by exploiting a normally helpful and ubiquitous group of molecules known as mucins. Now, Stanford researchers have engineered a biomolecule that removes mucins specifically from cancer cells — a discovery that could play a significant role in future therapies for cancer. Mucins […]
Brain cells of males and females respond differently to chronic stress
Scientific excellence requires diversity — research conducted by men and women, by people from different backgrounds and with varied worldviews. The need for diversity extends to scientific experiments themselves, but even today the vast majority of studies in the life sciences are done on male mice only, which could harm […]
Inhalation drug prevents severe pneumonia: Sugar molecule accurately delivers RNA drug to target cells
Overly active immune cells are often behind lung damage in diseases such as Covid-19. Researchers at the Technical University of Munich (TUM) have developed an RNA agent for a lung spray that slows the activity of these cells, known as macrophages. A new, sugar-based transport mechanism is especially effective in […]
How the Epstein-Barr virus transforms B cells
ells or B lymphocytes are an important part of the body’s immune system. When healthy B cells are infected with the Epstein-Barr virus (EBV), they undergo growth transformation, a process that immortalizes B cells, leading to their uncontrolled proliferation. The induction of immortalized B cells is the first step in […]
