  • Publication number: 20250206837
    Abstract: The present disclosure provides antibodies which specifically bind to human CD36 protein (hCD36) and are capable of decreasing, inhibiting, and/or fully-blocking immune regulatory effects and/or ligand transport into cells mediated by CD36. Examples of CD36-mediated effects, among others, may include oxidized lipid transport into CD8 T cells potentially causing cell death and fatty acid transport in regulatory T cells increasing their survival and immune suppression in the tumor micro-environment (TME). The present disclosure also provides methods of using the antibodies (and compositions thereof) to treat various diseases and conditions responsive to decreasing, inhibiting and/or blocking CD36-dependent ligand transport into cells.
