Abstract: Provided is a prophylactic, symptom progress-suppressive, and/or therapeutic agent for an autoimmune disease. The agent lowers the risk of infections and reduces the burden of administration to patients. The prophylactic, symptom progress-suppressive, and/or therapeutic agent includes a PD-1 agonist as an active ingredient and is administered (a) 1 to 10 times within one month from the first administration, (b) in a total PD-1 agonist dose of 20 to 1250 ?g/kg, and (c) without requiring administration for at least 3 months after the last administration.
Abstract: The present invention provides antibodies directed against ICOS or a derivative thereof which neutralize ICOS engagement on Treg by inhibiting the fixation between ICOS and ICOS-L and abrogate proliferation of Treg induced by plasmacytoid dendritic cells. The present invention further provides antibodies directed against ICOS or a derivative thereof which induce IL-10 and IFN? production, induce CD4? T cells proliferation, reduce Tconv proliferation, and increase the immunosuppressive function of Treg.

Abstract: The disclosure provides a method for immunotherapy of a subject afflicted with cancer, comprises administering to the subject a composition comprising a therapeutically effective amount of an antibody that inhibits signaling from the PD-1/PD-L1 signaling pathway. This disclosure also provides a method for immunotherapy of a subject afflicted with cancer comprising selecting a subject that is a suitable candidate for immunotherapy based on an assessment that the proportion of cells in a test tissue sample from the subject that express PD-L1 on the cell surface exceeds a predetermined threshold level, and administering a therapeutically effective amount of an anti-PD-1 antibody to the selected subject. The invention additionally provides rabbit mAbs that bind specifically to a cell surface-expressed PD-L1 antigen in a FFPE tissue sample, and an automated IHC method for assessing cell surface expression in FFPE tissues using the provided anti-PD-L1 Abs.
