As
with innate immunity, the
adaptive immune system — the T cells and antibodies produced by B cells that target specific molecules on invading cells — contributes to pathology or may also fight against it.

immune system.
Until now, most researchers have focused on one of two strategies: attacking tumors
with antibodies, which activate the innate

These cells, along
with dendritic cells, recognize the incoming undigested food particles, toxic agents, and bacterial components as foreign invaders, and present them to cells of the
adaptive immune system called T and B lymphocytes, leading to clonal expansion (proliferation or multiplication of specific subsets of T and B cells) and recruitment of more pro-inflammatory
immune cells to the gut through a process called leukocyte homing.
