Researchers from Los Angeles’s university (UCLA) have developed synthetic T-cells that near-perfectly mimic form and function of the human version.
T-lymphocytes play a key role in the immune system. They are activated when infection enters the body and they flow through the bloodstream to reach the infected areas. Because they must squeeze between small pores, T-cells have the ability to deform to as small as one-quarter of their normal size. They also can grow to almost three times their original size, which helps them fight off the antigens that attack the immune system.
