Cell biologists and bioimaging expert team up to solve fourth dimension secrets

Cell biologists at the University of Illinois at Urbana-Champaign and Bar-Ilan University at Israel and a bioimaging expert at the University of Central Florida are teaming up in what they hope may lead to a major breakthrough in understanding of the three-dimensional organization of the nucleus over time and their role in certain diseases.

Myeloid cells can suppress immune response, promote brain metastasis

Scientists have long believed that the brain protects itself from an aggressive immune response to keep down inflammation. However, that evolutionary control may work against it when a cancer cell attempts to spread to the brain, researchers at the University of Notre Dame have discovered.

Genome-wide screens reveal new helpful and harmful COVID-19 related genes

Researchers at Yale University and the Broad Institute of MIT and Harvard screened hundreds of millions of cells exposed to the COVID-19 and MERS viruses and identified dozens of genes that both enable the viruses to replicate in cells and also those that seem to slam the door on the virus.

Study reveals new and essential details of how photoreceptors work

Moving around in the half-light is difficult but not impossible. To help us in this undertaking we have the rods, a type of light-sensitive cells (photoreceptors) present in the retina of vertebrates, capable of detecting very low lights which allow to move about even in poorly lit cellars or caves.

Neutrophils have more functions in the body than previously thought

Scientists at the Centro Nacional de Investigaciones Cardiovasculares have discovered that neutrophils, the most abundant cells of the innate immune system, have many more functions in the body than previously thought.

Researchers find a new therapeutic approach to combat leukemia

Leukemia frequently originates from the so-called leukemic stem cell, which resides in a tumor promoting and protecting niche within the bone marrow. Scientists from the Max Planck Institute of Biochemistry in Martinsried, Germany, have found a new way to make these cells vulnerable by specifically dislodging these cells from their niches.

Research findings could potentially help exploit the weaknesses of cancer cells

Every cell in our body constantly divides to form new cells. This happens without us even thinking about it. However, every single time a cell divides, a complicated process has to unfold just the right way for our cells to avoid sickness and death.

Study shows how genetic predisposition contributes to the development of multiple sclerosis

About half of the people with multiple sclerosis have the HLA-DR15 gene variant. A study led by the University of Zurich has now shown how this genetic predisposition contributes to the development of the autoimmune disease multiple sclerosis in combination with environmental factors.
