In experiments with mice, the researchers found that Paneth cells engineered to lack a functional ATG16L1 gene were five times more likely to die in the face of rising TNF - alpha signals than normal cells.

In a series of laboratory experiments, the researchers found that antibodies against HSV - 1 remain in the trigeminal ganglion (a group of nerve cells that receives signals from the eyes and face and is a key site of HSV infection) long after active virus infection is cleared, and that these maternal antibodies can travel to the fetal trigeminal ganglia.

The researchers dosed β2AR - containing discs with a small druglike compound that normally binds to the portion of the receptor facing out of the cell.

Whatever the source of pluripotent cells, Thomson says, researchers face the same scientific challenges — namely, understanding how to convert them into key tissues such as the beta islet cells that are impaired in diabetics, and then how to introduce them safely and effectively into humans.

The researchers found the firing rate of each face patch cell corresponds to a separate facial feature.

This allowed the researchers to blow random puffs of air at their faces, causing them to blink, and to use a non-invasive microscopy technique to look at how the relevant Purkinje cells respond.

The researchers found the firing rate of each face cell corresponds to separate facial features along an axis.

This barrier has been highly visible in the field of human embryonic stem cell research, where researchers in the United States must adhere to legislation and funding limitations that researchers in European countries have not faced.

AFP reports that Israeli researchers found that frequent cell phone users — described as people who chatter on mobiles more than 22 hours a month — had a nearly 50 percent higher risk than others of developing a tumor on the parotid gland (the largest of the salivary glands on the side of the face just in front of the ear).

Added together, the information contributed by each nerve cell lets the brain efficiently capture any face, researchers report June 1 in Ccell lets the brain efficiently capture any face, researchers report June 1 in CellCell.

After removing the effects of solar rotation and accounting for the angle of view of areas not facing directly toward Earth, the researchers could discern the so - called giant cell flow patterns (material moving east is depicted in red, that moving toward the west in blue), which cause supergranules to slowly drift across the surface of the sun.

The researchers knew they faced a major challenge: sorting and separating «sticky» epithelial cell progenitors without destroying them.

The Italian researcher faced prejudice and adversity as a woman and as a Jew, but went on to elucidate a growth factor essential to the survival of nerve cells

Genetically modified «hunter» T cells successfully migrated to and penetrated a deadly type of brain tumor known as glioblastoma (GBM) in a clinical trial of the new therapy, but the cells triggered an immunosuppressive tumor microenvironment and faced a complex mutational landscape that will need to be overcome to better treat this aggressive cancer, Penn Medicine researchers report in a new study this week in Science Translational Medicine.

The researchers then investigated how neurons reacted to different aspects of emotions, and how the activity of the face cells related to the decision made by the subjects.

Researchers who hope to use stem cells — the unspecialized cells that produce all of our tissues — to treat diseases face a dilemma.

The researchers developed algorithms from the face - cell feedback that enabled them to recreate composite facial images from monkey brain - cell activity (Cell, doi.org/b7cell feedback that enabled them to recreate composite facial images from monkey brain - cell activity (Cell, doi.org/b7cell activity (Cell, doi.org/b7Cell, doi.org/b73v).

Now, researchers reporting in Current Biology on September 21 have found that those cells light up even when a person sees a familiar face or object but fails to notice it.

Second, the researchers theorized that if each cell was indeed responsible for coding only a single axis in face space, each cell should respond exactly the same way to an infinite number of faces that look extremely different but all have the same projection on this cell's preferred axis.

First, once they knew what axis each cell encoded, the researchers were then able to develop an algorithm that could decode additional faces from neural responses.

The researchers dubbed these regions face patches; the neurons inside, they called face cells.
