B cells are a key part of the adaptive immune system because they create a type of protein called antibodies.
These antibodies bind to foreign substances, such as toxins and germs, to prevent them from entering a normal cell and causing infection.
B cells, while known for fighting outside infections, have also been linked to inside diseases such as cancer. In certain cancers, such as breast, ovarian, lung, and colon cancers, an increased number of B cells have shown higher survival outcomes. But in prostate cancer, the effect of B cells is still unknown, and researchers are still unsure whether B cells are helpful or harmful to survival rates.
Researchers have discovered that there is an abundance of B cells found in Black men compared to White men.
