Tissue patterning is an important process during embryo formation, which ensures that groups of cells are arranged in an appropriate manner that allows them to function properly.
Read moreNew research into the mechanics of cellular sleep and shutdown could shed light on the aging process and how to potentially intervene.
Read moreNeural crest cells have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest stages of embryonic development. But their capacity to form derivatives like bone and tooth-forming cells defies fundamental concepts in developmental and stem cell biology. A research team has found a solution to this mystery by demonstrating an earlier origin of the neural crest in chick embryos.
Read moreHuman-made toxic chemicals that linger indefinitely in the environment disrupt the performance of critical helper cells in the mouse brain, leading to impaired function over long-term exposures.
Read moreA phase 2 clinical trial using a new technology show it is possible to induce immune tolerance to gluten in individuals with celiac disease. After treatment with the technology, the patients were able to eat gluten with a substantial reduction in inflammation.
Read moreChronic stress during pregnancy triggers an immune response in the brain that has potential to alter brain functions in ways that could contribute to postpartum depression, new research in animals suggests.
Read moreA high-resolution bioprinting process has been developed: Cells can now be embedded in a 3D matrix printed with micrometer precision — at a printing speed of one meter per second, orders of magnitude faster than previously possible. Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework. This is achieved using so called 'bioprinting' techniques.
Read morePhagocytosis can be viewed as a primitive immune system used by all cells. When a pathogen is near the cell, the cell membrane will deform to engulf the pathogen and dispose of it. Researchers have found that a two-dimensional sheet formed by the protein GAS7 is critical for this process, identifying through crystallography and microscopy two key hydrophilic loops in the protein.
Read moreThe study, conducted in mice, is the first to show that creatine uptake is critical to the anti-tumor activities of killer T cells, the foot soldiers of the immune system.
