A new study shows that a 30-minute exercise session can increase the proportion of tumor-killing white blood cells in the bloodstream of breast cancer patients. White blood cells, the cells of our immune system, fight against cancer, bacteria, and viruses. The most important cell types that destroy cancer cells are cytotoxic T cells and natural killer cells. Cell types that support cancer growth include, for example, regulatory T cells and myeloid derived suppressor cells. Twenty breast cancer patients who had just been diagnosed and therefore had not yet started their cancer treatments participated in the study. During the study, the...

Disintegrating Virus Cell Destroy COVID Concept The injection causes type B white blood cells to be genetically engineered inside the patient’s body that would generate neutralizing antibodies against the HIV virus. The technology also has the potential to be developed into a cure for AIDS Adi Barzel Lead author of the study, Dr. Adi Barzel. Credit: Tel Aviv University A new study from Tel Aviv University proposes a novel AIDS treatment that could be turned into a vaccine or a one-time treatment for HIV patients. The research explored modifying type B white blood cells in the patient’s body to release...

Research has shown that time in space can increase the risk of cancer and trigger gene mutations. But a new study has found that one crucial part of the human body remains unaffected by zero-gravity. in space didn’t alter an astronaut’s levels of B-cell immunity — the white blood cells that create antibodies to fight off infections. B-cell levels need to be maintained in order to help astronauts fight off disease-causing viruses and bacteria. For the study, scientists took blood samples from 23 crew members stationed at the International Space Station for six months, before, during and after their stays....

Fasting for as little as three days can regenerate the entire immune system, even in the elderly, scientists have found in a breakthrough described as “remarkable”. Although fasting diets have been criticized by nutritionists for being unhealthy, new research suggests starving the body kick-starts stem cells into producing new white blood cells, which fight off infection. Scientists at the University of Southern California say the discovery could be particularly beneficial for people suffering from damaged immune systems, such as cancer patients on chemotherapy. […] Scientists found that prolonged fasting also reduced the enzyme PKA, which is linked to aging and...

But new research suggests that hydrogen peroxide does more than just kill microbes. It may also call for reinforcements, summoning an army of bacteria-fighting cells to cuts and wounds. Punctured skin sets off a chain reaction of chemical signals...

EVANSTON, Ill. -- A recent Northwestern University study found that a new treatment using stem cells might extend the lives of patients with lupus. Stem cell treatments could help patients with severe cases who have not responded to other options, according to a study published in the Feb. 1 issue of The Journal of the American Medical Association. Lupus is a disease that causes patients' immune systems to become unable to distinguish between foreign substances and normal parts of the body. This causes the immune system to attack the patient's own cells and tissues instead of protecting them. Researchers, including...

On the day a priest came to her hospital bed and prayed over her withered body, Diana Abad would not have believed good fortune awaited. Or seemed to be, until one day her back started to ache and another day her legs swelled. She had her blood tested and learned her white-cell count was absurdly high. Leukemia, her doctor said. Without a bone-marrow transplant, she would be dead in nine months. David Mason would not have believed in 1990 that by checking a box on a Navy form he would set in motion the chain of events that led him...
