Uso de neutrófilos em doentes com cancro?

Injecção por algumas semanas cura? Vai ser testado:

Citando:
"A radical radical  new cancer treatment inspired by patients who seem to ‘shrug off’ the disease could be tested next year.

The technique uses potent cancer-killing cells from people with the strongest immune systems.

These ‘neutrophil’ cells – which form part of the body’s first line of defence – are then multiplied millions of times and injected into cancer patients.

They are believed to be a key reason why rare individuals spontaneously reject lethal cancers and seem to have ‘miracle recoveries’."
(...)
"But when they do target cancer, they are highly efficient – wiping out 95 percent of test cancer cells in 24 hours. It is neutrophils with this ability that form the basis of the new therapy.

The Lift team has collected thousands of the cells discarded as a waste product by blood banks, and is mass-screening them for their cancer-killing potential in a laboratory.

Those that pass the test are cultured and multiplied many times over using a secret process. The researchers are also working on a way of altering them to become even more potent."

O que acontece quando um mosquito nos pica

... E como evitar que os vírus se propaguem:

Citando:
"When mosquitoes bite, they probe the skin and inject saliva, causing an inflammation and triggering an immune response. White blood cells called neutrophils and myeloid cells rush to the site of the bite, but the researchers show that instead of helping, these cells in fact get infected and inadvertently replicate the virus."
(...)
"Potential treatment
These findings suggest that anti-inflammatory drugs and creams could be an interesting therapeutic option to limit the spread of the virus. They could potentially target the inflammation before the immune cells rush to the site of the bite and become infected by the virus. This could an important step in fighting viral diseases (...)"
