Such a discovery is important because it reveals a common viral theme that may be vulnerable to disruption and could lead to the development of drugs to treat many different kinds of viral infections, much like antibiotics are used to attack different kinds of bacter...New, more direct pathways from outside the cell-to-cell nuclei discovered

The discovery explains how plants can time their growth to take advantage of resources such as light and water, and suggests that many other processes may be influenced by circadian rhythms.

This discovery led Han and her colleagues to attempt to block the inflammatory process by using synthetic TLR4 antagonist that prevented the receptor from sensing the bacteria.

That discovery led the researchers to conclude that, at least under optimal laboratory conditions, Drosophila can tolerate a significant number of bacteria and mount a strong innate immune response against them without cutting their 65-day lives any shorter.

The novelty of our study is the discovery that Bcl-3 acting on gene expression has a profound effect on inflammation, says Ruaidhri Carmody, PhD, Senior Research Investigator in the Department of Pathology and Laboratory Medicine and first author of the Science paper.

The discovery that a variation in a serotonin-related gene could affect response to citalopram was not entirely surprising, since the serotonin system is known to be involved in depression.
