title: Development and characterization of a monoclonal antibody specific for bovine CD209.
abstract: Dendritic cells (DC) play a central role in tailoring the immune response to pathogens. Effector activity is mediated through pattern recognition receptors (PRRs) that recognize pathogen associated molecular patterns (PAMPS). C-type lectin receptors (CLR) comprise a group of PRRs that recognize a broad range of pathogens. CD209 (DC-specific ICAM3-grabbing non-integrin, DC-SIGN) is a CLR expressed on DC that plays a critical role on DC function and pathogen recognition. It facilitates DC migration to peripheral tissues and local lymph nodes and mediates T cell activation by binding ICAM-2 (CD102) and ICAM-3 (CD50). The absence of monoclonal antibody (mAb) to bovine CD209 has limited the ability to characterize the phenotype and function of DC in cattle. To address this issue we developed and used a mAb to CD209 to characterize the phenotype of CD209 expressing cells in bovine blood using flow cytometry. Initial analysis has revealed the CD209 positive population in blood is comprised of multiple phenotypically defined subsets.
