immunology

Promising work just published in the journal Nature Medicine offers hope when antibiotic resistance, in an extremely sick patient, renders limited treatments.
A new study that says oral sex can prevent miscarriage predictably has gone viral, thanks mostly to the rather excitable British tabloids. But is it true? If it is, the study doesn't even come close to confirming the hypothesis.
A rare genetic disorder that transforms a person's hands and feet, in particular, into tree-bark-like warts and cutaneous horns made news recently. It's truly out of the ordinary. So what's this all about? 
Perhaps the strangest medical phenomenon discovered in recent years is a link between the lone star tick and an allergy to red meat. The bite of a lone star tick exposes a person to a small carbohydrate called alpha-gal. In a handful of people, this exposure elicits an abnormal immune response that produces a type of antibody called IgE, which causes allergies. Because red meat also contains alpha-gal, people who have been sensitized to the carbohydrate from a tick bite can develop life-threatening anaphylaxis if they consume pork or beef. 
Cow's milk allergies
In an effort to understand how cow's milk allergies (CMA) form, an interdisciplinary team of scientists investigated if there's a link between certain kinds of sugars found in a mother's breast milk and the presence of CMA in her infant.
A drop in T-cell production may mean that astronauts are at least temporarily immunocompromised by space flight. To those of you who are eager for a trip to Mars, add "immunosuppression" to your list of concerns.
