Experts have argued the high-tech ink that fades gradually over a week and when drugs are released, could be available soon
scientists have found drugs last longer in the bloodstream compared to those injected
experts said the method does the drug more available for absorption by T cells – .. a type of white blood cells essential to the immune system.
however, scientists found that marked the skin, but with imagination the new drug delivery system could be made in the body art, such as cartoons for children.
scientists at Baylor College of Medicine tested antioxidants nanoparticles created at Rice University and found they were absorbed by cells of the immune system.
That could be an advantage for patients with autoimmune diseases such as multiple sclerosis
Associate Professor of Baylor Dr Christine Beeton said :. “Placed just under the skin, particles based on carbon form a dark stain fades for about a week, and slowly released into the circulation [
” saw that made a mark in black when It injected, and at first we thought it will be a real problem if ever we get to the clinic. But we can work around that.
“We can inject in an area that is hidden, or use micropattern needles and shape.
” I can see doing this for a child who wants a tattoo and never I could get her parents to go along. This is a good way to convince them. “
The study found that cells and macrophages of T and B lymphocytes are key immune system components. In many autoimmune diseases such as multiple sclerosis, T cells are the main actors.
But one suspects that the cause is that T cells lose their ability to distinguish between invaders and healthy tissue and attack both.
in tests Baylor nanoparticles were internalized by T-cells, which inhibited its function but ignored by macrophages.

Redwan Huq, lead author of the study, said. “most current treatments are not immunosuppressants, broad overall spectrum
” They will affect all these cells, but patients are exposed to the effects ranging from infections to further increase the chances of developing cancer.
“So we were excited when we see something new that could potentially allow selectivity.”
Because macrophages and other immune spleen cells are not affected, more than a patient’s existing immune system remains intact, he said
The study was published in the journal Scientific Reports
