Study unravels the DNA repair mechanism by enzymes

A new study by researchers from the Gwangju Institute of Science and Technology in the Republic of Korea has revealed the mechanism of DNA repair by enzymes exonuclease III and polymerase I by utilizing single molecule fluorescence resonance energy transfer (smFRET)-enabled dynamic observation.

Newly identified antibacterial mechanism could inspire novel strategies to combat bacterial pathogens

Similar to how a spider traps its prey, the cells of the human immune system cooperate to trap and “eat” bacteria.

Research identifies an unnoticed site for priming of CD8+ T cells—the spleen

CD8+ T cells, also called “killer” T cells, are the killers of the immune system. Upon being primed, they look for and kill cancerous cells or virus-infected cells.

Food science principles help explain the biology behind cellular compartments

Johns Hopkins Medicine researchers report that food science principles have helped them determine how unusual droplets within cells stay organized and avoid dissolving into the rest of the cell's gelatinous interior.

Loss of natural HIV control preceded by functional impairment of T cells

HIV is a master of evading the immune system, using a variety of methods to prevent the body from being able to find and kill it.

UAB researchers identify an unnoticed additional site for priming of "killer" T cells

CD8+ T cells -; known as "killer" T cells -; are the assassins of the immune system. Once they are primed, they seek out and destroy other cells that are infected with virus or cells that are cancerous.

Viruses buried in marsupials' DNA may help protect against future infections

Fossils of ancient viruses are preserved in the genomes of all animals, including humans, and have long been regarded as junk DNA. But are they truly junk, or do they actually serve a useful purpose?

Stem cell transplantation leaves no scars in the DNA of transplanted cells

Stem cell transplants do not lead to changes in the DNA of the donor cells. That's according to a new study, which provides important evidence for the safety of this procedure.
