Emerging immune checkpoint leukocyte immunoglobulin\u2010like receptor B1 (LILRB1)\u00a0and LILRB2 have been proposed as therapeutic targets, yet their in vivo function remains undefined due to the lack of cross\u2010reactive blocking antibodies for relevant preclinical models. Here, we developed a dual\u2010specific blocking monoclonal antibody, mac20G10, targeting cynomolgus macaque LILRB1 and LILRB2 and assessed its immunomodulatory activity in an SIV model of infection. Pharmacodynamic analyses demonstrated that mac20G10 persisted in circulation and engaged target myeloid cells for up to 14 days without detectable adverse effects. A single administration prior to SIVmac251 infection enhanced early myeloid immune activation, characterized by increased frequencies of CD80\n                    <jats:sup>+<\/jats:sup>\n                    plasmacytoid dendritic cells (pDCs) and CD80\n                    <jats:sup>+<\/jats:sup>\n                    monocyte\/macrophage subsets in blood and lymphoid tissues. These changes were accompanied by increased plasma levels of interferon lambda (IFN\u2010\u03bb), IL\u20108, and IL\u20101RA during acute infection. Although viral replication remained unchanged, mac20G10 treatment promoted the development of SIV\u2010specific memory CD8\n                    <jats:sup>+<\/jats:sup>\n                    T\u2010cell responses. Together, these data show that LILRB1\/B2 blockade modulates early myeloid activation and is associated with enhanced SIV\u2010specific memory CD8+ T\u2010cell responses. These findings support further evaluation of LILRB1\/B2 blockade as part of combination immunotherapeutic strategies in settings such as ART\u2010treated infection and analytical treatment
