Spleen-on-a-chip could treat bloodstream infections

Spleen-on-a-chip could treat bloodstream infections | Longevity science | Scoop.it

The spleen’s job is to filter our blood. When people are critically ill or have received traumatic injuries, however, the spleen alone is sometimes not able to remove enough of the pathogens on its own – potentially-fatal sepsis is the result. In order to help avert such an outcome in those situations, scientists from the Wyss Institute for Biologically Inspired Engineering at Harvard University are developing a device known as the spleen-on-a-chip.

 

The patient’s blood is circulated through the device. The process begins with magnetic nanobeads being mixed with the blood. Those beads are coated with a genetically engineered version of a human blood opsonin protein, that bonds with pathogens such as bacteria, viruses, parasites, fungi and toxins.

New hope for people with broken spines: Stem cells bring back feeling for paralysed patients

New hope for people with broken spines: Stem cells bring back feeling for paralysed patients | Longevity science | Scoop.it

For the first time, people with broken spines have recovered feeling in previously paralysed areas after receiving injections of neural stem cells. Three people with paralysis received injections of 20 million neural stem cells directly into the injured region of their spinal cord.

 

The cells, acquired from donated fetal brain tissue, were injected between four and eight months after the injuries happened.The patients also received a temporary course of immunosuppressive drugs to limit rejection of the cells. None of the three felt any sensation below their nipples before the treatment.

 

Six months after therapy, two of them had sensations of touch and heat below their belly button. The third patient has not seen any change. The patients are the first three of 12 who will eventually receive the therapy. The remaining recipients will have less extensive paralysis.
