– RC529-MDP is an immunological adjuvant that couples Toll-like receptors (TLR4a) and NOD-like receptors (NOD2a) to enhance the innate immune response through the TLR4 and NOD2 signaling pathways. In mouse models, RC529-MDP induces high levels of the cytokine interleukin-related factor (IL-6), highlighting its immunostimulatory activity. Additionally, when injected into mice models with ovalbumin (OVA), RC529-MDP elevates OVA-specific antibody responses, T cell responses, and the proportion of memory T cells.
