Abstract: The present disclosure provides an isolated monoclonal antibody or an antigen-binding fragment thereof that binds specifically to leukocyte immunoglobulin-like receptor 4 (LILRB4). In certain embodiments, the antibody or antigen-binding fragment, when bound to LILRB4, modulates the activation of LILRB4. In certain embodiments, the antibody or antigen-binding fragment, when bound to LILRB4, activates LILRB4. In certain embodiments, the antibody or antigen binding fragment, when bound to LILRB4, suppresses activation of LILRB4. In certain embodiments, the antibody or antigen-binding fragment, when bound to LILRB4, specifically blocks binding of ApoE to LILRB4. In another aspect, there is provided a method of treating or ameliorating the effects of a cancer in a subject, comprising administering to the subject a therapeutically effective amount of the antibody or an antigen-binding fragment thereof or an engineered cell as provided herein.
