The present invention describes combination treatment comprising a PD-1 axis binding antagonist and an agent that decreases or inhibits TIGIT expression and/or activity and methods for use thereof, including methods of treating conditions where enhanced immunogenicity is desired such as increasing tumor immunogenicity for the treatment of cancer or chronic infection. 1166.-. (canceled)167. A method of treating cancer in a human subject in need thereof , comprising administering to the human subject an effective amount of:a. an anti-PD-L1 antagonistic antibody; andb. an anti-TIGIT antagonistic antibody.168. The method of claim 167 , wherein the anti-TIGIT antagonistic antibody is a human antibody or a humanized antibody.169. The method of claim 167 , wherein the anti-TIGIT antagonistic antibody is a monoclonal antibody.170. The method of claim 167 , wherein the anti-TIGIT antagonistic antibody is a monoclonal humanized antibody.171. The method of claim 167 , wherein the anti-TIGIT antagonistic antibody is a monoclonal human antibody.172. The method of claim 167 , wherein the anti-TIGIT antagonistic antibody is an IgG antibody.173. The method of claim 172 , wherein the anti-TIGIT antagonistic antibody is an IgG-1 antibody.174. The method of claim 173 , wherein the anti-TIGIT antagonistic antibody is a monoclonal human IgG-1 antibody or a monoclonal humanized IgG-1 antibody.175. The method of claim 172 , wherein the anti-TIGIT antagonistic antibody is an IgG-4 antibody.176. The method of claim 175 , wherein the anti-TIGIT antagonistic antibody is a monoclonal human IgG-4 antibody or a monoclonal humanized IgG-4 antibody.177.
