...pecific locations in the body. "The liver takes up foreign substances in the body, so it's not surprising that that's where we saw the particles," Rosol said. "But we ultimately want to be able to make these particles to go to the mammary glands or other tissues we're interested in." The ultrasound images gr...

Despite the foreign surroundings, the bovine cells survived for long periods, up to three months, although they failed to fully develop into sperm, said de Rooij.

Lab tests revealed that the B cells in enlarged spleens had stopped evolving in the pre-B phase, right at the point where a B cell normally begins to create structures necessary for antibody development....

Rutgers team's coal-to-diesel breakthrough could drastically cut oil imports

The team chose nanoparticles as drug-delivery vehicles because they are so small that living cells readily swallow them when they arrive at the cell's surface. Langer said that particles larger than 200 nanometers are le...

"This finding was a big surprise because most of these endogenous viral genomes have undergone such mutation and deletion that they are incapable of giv...

However, a specialized subset of T cells, known as regulatory T cells (Tregs) helps to ensure that the T cell response doesn't get out of control and lead to autoimmune disorders. Just how Tregs mediate this control has not been fu...
