MIT researchers have shown that they can use a microfluidic cell-squeezing device to introduce specific antigens inside the immune system’s B cells, providing a new approach to developing and implementing antigen-presenting cell vaccines.
Such vaccines, created by reprogramming a patient’s own immune cells to fight invaders, hold great promise for treating cancer and other diseases. However, several inefficiencies have limited their translation to the clinic, and only one therapy has been approved by the Food and Drug Administration.
While most of these vaccines are created with dendritic cells, a class of antigen-presenting cells with broad functionality in the immune system, the researchers demonstrate in a study published in Scientific Reports that B cells can be engineered to serve as an alternative.
