Protein prevents detrimental immune effects of bacterial sepsis

...ecause it appears to be involved in the resolution phase of the immune response: its expression on white blood cells impairs their ability to bind blood vessel walls, preventing their transit from the blood to other organs. When normal mice were treated with LPS, the immune system induced a steady migrati...

Researchers make surprise discovery that some neurons can transmit three signals at once

The first week after birth marks a critical phase in the developing rat brain, a time period comparable to three months gestation in a human, when neurons are meticulously organizing and self-selecting to assemble into specific brain structures and neuronal networks. It has long been known that a sp...

Stem cell treatment improves mobility after spinal cord injury

...rently, drug treatments are given during the acute phase to help stabilize the injury site, but they provide only a very mild benefit, and they do not foster regeneration of insulation tissue. For the study, the UCI team used a novel technique they created to entice human embryonic stem cells to different...

Likewise, regular patterns of filaments have been shown to lead to enhanced motor diffusion along the substrate surface. All of these results have been obtained from a combination of analytical calcula...
