Lymphocyte activating gene  3 (LAG3)  Is a member of the immunoglobulin superfamily , Combine with high affinity  MHC II  class , Negative regulation  T  Cell function and homeostasis . It's in  B、T  and  NK  cells 、 It is expressed in monocytes and dendritic cells , And play a regulating role  T  The role of cell expansion .LAG3  It is also an important immune checkpoint protein , resist  LAG3  Antibodies can activate  T  Effector cells and affect regulatory  T  Cell function . Besides ,LAG3  It seems to be with  PD-1/PD-L1  Work in a collaborative way , This indicates that the double antibody method may prove useful in cancer immunotherapy .
