Yeast Supplement Boosts Cancer-Fighting Immunity in Mice

Topic: Health

Researchers at Trinity College Dublin and University College Dublin found that a yeast-based dietary supplement can strengthen immune cells involved in fighting cancer. They tested this on obese mice and saw improved results compared to those who didn't receive the supplement.

Researchers at Trinity College Dublin and University College Dublin (UCD) have made an exciting discovery about how to boost our bodies' ability to fight cancer. They found that a yeast-based dietary supplement can strengthen immune cells involved in fighting cancer in mice.

The researchers tested this on obese laboratory mice, which are prone to having weaker immune systems due to their weight. The mice were given the supplement for 4-12 weeks and then challenged with different types of cancer cells. The results showed that the mice who received the supplement had stronger immune responses compared to those who didn't.

This is important because obesity can interfere with our bodies' ability to fight off tumors, making it harder to recover from cancer. The researchers hope that this discovery could lead to new ways to help people with weakened immune systems due to obesity or other factors.

The study was led by Frederick Sheedy and Helen Roche, who are experts in immunology and nutrigenomics respectively. They used a type of yeast called beta-glucan, which is already sold as a dietary supplement and has been shown to be safe for human consumption.

Why It Matters

This discovery could lead to new ways to help people with weakened immune systems due to obesity or other factors, potentially improving cancer treatment outcomes in India where obesity is on the rise.
