Researchers at Washington University School of Medicine in St. Louis have identified a parasite protein that has all the makings of a microbial glass jaw: it's essential, it's vulnerable and humans have nothing like it, meaning scientists can take pharmacological swings at it with minimal fear of collateral damage.

The Burnier International Ocular Pathology Society is holding a Scientific Colloquium in Montreal today to mark the tenth anniversary of the McGill University Health Centre's Henry C. Witelson Ocular Pathology Laboratory. The lab is an internationally reputed centre for the study and treatment of eye diseases and is leading a global network for the sharing of healthcare knowledge and expertise.

A new article published in the peer-reviewed journal Women's Health emphasizes the importance of early pregnancy detection. Using research conducted on behalf of Church & Dwight Co. Inc., the makers of First Response, the article reviews data that shows not all at-home pregnancy tests are created equal -First Response brand pregnancy tests are more sensitive and able to detect key variants of the pregnancy hormone better than other at home pregnancy tests.

Our immune cells have an amazingly intricate recognition system to detect invading pathogens. Often, the intricacies have overwhelmed scientists who want to know exactly what gives an alarm signal to T cells, a class of white blood cells that recognizes invaders.

St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide. The researchers found that the microbes block nitric oxide production by subverting the biochemical machinery used by immune cells called macrophages to produce the chemical.

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

A new drug that will soon enter clinical trials for treatment of malaria also appears to be 10 times more effective than the key medicine in the current gold-standard treatment for toxoplasmosis, a disease caused by a related parasite that infects nearly one-third of all humans—more than two billion people worldwide.

One of the most common human parasites, Toxoplasma gondii, uses a hormone lifted from the plant world to decide when to increase its numbers and when to remain dormant, researchers at Washington University School of Medicine in St. Louis have found.
