Wouldn't they be digested?" - correct answersYes, antibodies are proteins, but infants have immature gastroinestinal tracts, and they absorb some proteins whole without their being digested. "How do my white blood cells know how to get to this infected mosquito bite?" says David, age 14. "I thought white blood cells are in the blood." - correct answersYes, white blood cells are in the blood, but when a mosquito bite gets infected, the injured area sends out chemical distress signals. Some of the white blood cells leave the blood and follow the chemical signals, which get stronger the closer they get to the mosquito bite. That is how white blood cells know to come and help get rid of the infection. "I understand why it hurts, but what makes a sprained ankle swell up like that?" asks Mrs. Kellerman. - correct answersWhen you sprain your ankle, the injured tissue puts out chemical messengers that act on nearby blood vessels. They expand and let more blood flow into the injured tissue, and the blood vessels become leaky. Leaky blood vessels allow fluid from the blood to leak into the tissues, which makes them swell. "My doctor said I got this fungus because penicillin killed off my normal microbiome," says Mrs. Hunt. "What does 'normal microbiome' mean?" - correct answersThe term normal microbiome means the good bacteria and other microorganisms that normally live on your skin and in areas of your body like the gastrointestinal tract. These normal microbiome microorganisms help keep disease causing microorganisms, like that fungus, from causing an infection.l When the penicillin killed off some of the normal microbiome, the fungus had an opportunity to grow in their place. "My physician said my cancer drugs gave me a secondary immunodeficiency, so I get sick easily," says Mr. Erie. "I think it is important! Why did she say it is secondary?" - correct answersCalling it a secondary immunodeficiency does not mean that is unimportant. It means that the immunodeficiency was caused by something outside your immune system, rather than being a problem that started with your immune system. As you know, the cancer drugs suppressed your immunity. That is why we call it secondary immunodeficiency. We think it is very important also and are working to protect you from infection.
