Cell-killing proteins suppress listeria without killing cells

New North Carolina State University research shows that key proteins known for their ability to prevent viral infections by inducing cell death can also block certain bacterial infections without triggering the death of the ...

How viruses outsmart their host cells

Viruses depend on host cells for replication, but how does a virus induce its host to transcribe its own genetic information alongside that of the virus, thus producing daughter viruses? For decades, researchers have been ...

Chlamydia attacks with Frankenstein protein

When Chlamydia trachomatis, the bacterium that causes one of the most common sexually transmitted infections worldwide, infects a human cell, it hijacks parts of the host to build protective layers around itself.

Co-evolution between a 'parasite gene' and its host

A Danish research team has delineated a complex symbiosis between a 'parasitic' noncoding RNA gene and its protein-coding 'host' gene in human cells. The study reveals how co-evolution of the host gene and parasite gene has ...

Protein interaction helps Yersinia cause disease

Researchers at UmeƄ University, Sweden, in collaboration with an international team, have discovered a new mechanism for interaction between two proteins that are vital for the Yersinia pseudotuberculosis bacteria's pathogenic ...

A new twist on how parasites invade host cells

Toxoplasmosis is a widespread infection caused by the parasite Toxoplasma gondii, which multiplies within a host and irreversible tissue damage. Humans primarily become infected by eating undercooked meat and poorly washed ...
