Transposable Elements Are Key to Normal Progression of Embryonic Cells

A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found.

Mutant Neurons Show Accelerated Development in Mouse Brain

The mechanisms behind intellectual disabilities and autism remain largely unknown. However, researchers from the labs of Prof. Pierre Vanderhaeghen and Prof. Vincent Bonin at the VIB-KU Leuven Center for Brain & Disease Research and NERF have identified that mutations in the SYNGAP1 gene interfere with the extended development of human neurons, a process believed to be critical for normal cognitive function.

New Mouse Model Shows Superior Ability to Study Human Immune Response to Cancer

Immunity plays a central role in the fight against cancer. Many of the current immunotherapies aim at helping the patient's immune system to better recognize cancer cells – by using engineered antibodies – or by simply providing it with new cells, pre-equipped to search and destroy cancer. Either way, what is paramount is a deep understanding of how the immune system works and confronts tumors.

New Discovery Reveals How MX Protein Traps HIV and Herpes Viruses

A group of researchers led by Xavier Saelens and Sven Eyckerman at the VIB-UGent Center for Medical Biotechnology discovered how a protein linked to the human immune system wards off HIV-1 and herpes simplex virus-1 by assembling structures in the cell that lure in these viruses and then trap them or even take them apart.
