Selectively altering microbiota for immune modulation
First Claim
1. A method for modulating a therapy of a disease or condition in a human or animal patient, the method comprises altering the relative proportion of a sub-population of gram negative bacteria in a microbiota of the patient by administering a bacterial transplant to the patient, wherein the therapy comprises administration of an effective amount of an immune checkpoint inhibitor to the patient, wherein the immune checkpoint inhibitor is a PD-1 (programmed death-1) inhibitor or a PD-L1 (programmed death-ligand 1) inhibitor, and wherein the bacterial transplant comprises Akkermansia or Faecalibacterium.
