Adding bifidobacteria into the digestive tracts of mice increased their immune system's ability to attack tumor cells.
Adam Rifkin stashed this in Microbiome
Research carried out at the University of Chicago and published recently in Science found that adding certain bacteria into the digestive tracts of mice increased their immune system's ability to attack tumor cells.
The positive effect of the added bacterial flora was similar in strength to those of checkpoint inhibitors, a type of successful anti-tumor drug.
When oral doses of bacteria were given in conjunction with checkpoint inhibitors, tumor outgrowth was almost abolished.
Study Director Dr. Thomas Gajewski said:
"Our results clearly demonstrate a significant, although unexpected, role for specific gut bacteria in enhancing the immune system's response to melanoma and possibly many other tumor types."
As further investigation into this phenomenon is carried out, perhaps there will be a discovery that likens the functionality of gut bacteria to be very similar to how our immune system works, implying that getting a fecal transplant from cancer survivors would be more effective than any random person.
