HIV & AIDS
Study suggests a way to stop HIV in its tracks
When HIV-1 infects an immune cell, the virus travels to the nucleus so quickly there's not enough time to set off the cell's alarm system.

Researchers use stem cells to show connection between neural cell disruption and Parkinson's disease
(Medical Xpress)—A diverse team of biologists has shown using induced pluripotent stem cells (iPSCs) that a gene mutation that causes malformations in the structure of the nuclear envelope of neural cells, is associated ...

RNA spurs melanoma development
Traditionally, RNA was mostly known as the messenger molecule that carries protein-making instructions from a cell's nucleus to the cytoplasm. But scientists now estimate that approximately 97 percent of human RNA doesn't ...

Scientists reverse a key hallmark of motor neuron disease in the laboratory
Scientists at the Francis Crick Institute and UCL have studied how proteins accumulate in the wrong parts of brain cells in motor neuron disease, and have demonstrated how it might be possible, in some cases, to reverse this.

How cytoplasmic DNA triggers inflammation in human cells
A team led by LMU's Veit Hornung has elucidated the mechanism by which human cells induce inflammation upon detection of cytoplasmic DNA. Notably, the signal network involved differs from that used in the same context in ...

Removing protein 'garbage' in nerve cells may help control two neurodegenerative diseases
Neuroscientists at Georgetown University Medical Center say they have new evidence that challenges scientific dogma involving two fatal neurodegenerative diseases—amyotrophic lateral sclerosis (ALS), and frontotemporal ...

Newly identified mechanism of p53-induced cell death could aid cancer therapy
Researchers have identified a new mechanism that the tumor suppressor protein p53 uses to trigger cell death via apoptosis and have shown how the process could be harnessed to kill cancer cells. St. Jude Children's Research ...

Weill Institute researchers uncover basic cell pathway
Although all cells in an organism have the same DNA, cells function differently based on the genes they express. While most studies of gene expression focus on activities in the cell's nucleus, a new Cornell study finds that ...

Viruses kill pancreatic tumors in preclinical model
(Medical Xpress) -- An intra-tumor injection of a virus prevented further growth of some pancreatic tumors and eradicated others in mouse models of pancreatic ductal adenocarcinoma. However, some tumors continued growing ...
