immune system

“You can think of the human immune system as an orchestra playing together and needing a co-ordinated performance from all the musicians and their instruments. It doesn’t make scientific sense to talk about antibodies or T-cells on their own.”
Roaming through your body is a group of specialized immune cells which act stealthily and authoritatively. They "ask" other body cells to show them identification ("papers please!"). If they fail to provide adequate ID those cells are killed on the spot. No questions asked. Scientists are now recruiting these cells to help in the fight against cancer.
You don't need to purchase an air purifier for your house. You have a built-in air purifier called the respiratory system.
Everyone knows by now that astronauts get more herpes outbreaks. Big deal. But did you ever consider what a game-changer this could be for those who might accidentally pick up a little contagion while seeking pleasure outside the marriage? No more "I got it from the toilet seat." Now you have a better excuse. Will you join this club, 62 miles up?
This flu season, one product is making its comeback: orange juice. Sales of OJ seem to have gotten a boost — after years of decline — due to consumers' fears of getting the dreaded illness.  But is dosing yourself with high amounts of Vitamin C warranted for this year's flu from hell?                  
Those with severe eczema can suffer mightily from itching, which leads to scratching, which makes it worse. Anti-inflammatory steroids are the go-to drugs (but they have many nasty, long-term side effects). But an antibody drug named Dupixent, just approved by the FDA, works very well. So now you may be able to give your fingernails a rest.  
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.
A colder temperature slows down a viral-infected cell's ability to commit suicide.
The human body's immune system is similar to having millions, if not billions, of snipers at the ready aiming and poised to shoot any foreign invader. This is why transplanted tissues and organs are so vulnerable to rejection. But a recent discovery by MIT researchers hopes to make them more viable.
When a mild fever strikes healthy kids or adults, that small temperature rise is usually followed with a move towards the medicine cabinet. But there's a broad body of research that indicates that so-called over-the-counter remedies are simply unnecessary, because the body is perfectly designed to handle this physiological intrusion.
We ve written several times about the Disneyland measles outbreak that occurred earlier this year. A total of 147 people were sickened in the US, and infections also spread to Mexico and Canada. The outbreak once again sparked the debate about vaccinations. With
