CD180. also known as LY86 or RP105-associated transmembrane protein, is a cell surface glycoprotein belonging to the Toll-like receptor (TLR) family. Primarily expressed on B lymphocytes, dendritic cells, and macrophages, it plays a regulatory role in innate immunity and inflammatory responses. Unlike canonical TLRs, CD180 lacks a conserved intracellular Toll/interleukin-1 receptor (TIR) domain but associates with MD-1 to form a heterodimer critical for ligand recognition and signal modulation.
Structurally, recombinant CD180 proteins are typically produced using mammalian expression systems (e.g., HEK293 cells) to ensure proper post-translational modifications. These proteins retain the extracellular leucine-rich repeat (LRR) domains essential for binding pathogen-associated molecular patterns (PAMPs), though their specific endogenous ligands remain less defined compared to other TLRs.
Functionally, CD180 regulates B-cell activation and survival through crosstalk with TLR4 signaling pathways. Studies suggest it fine-tunes immune responses by either enhancing or suppressing downstream NF-κB and MAPK signaling, depending on cellular context. Its recombinant form has become a valuable tool for investigating immune tolerance mechanisms, vaccine adjuvant development, and autoimmune disease research. Notably, CD180 shows altered expression patterns in chronic lymphocytic leukemia and rheumatoid arthritis, highlighting its clinical relevance. Current research focuses on elucidating its ligand specificity and therapeutic potential as a target for immunomodulation.
