Product details:
The antigen recognized by ER-TR9 has recently been shown to be the murine analogue of the human DC SIGN (Dendritic Cell - Specific ICAM3 Grabbing Non Integrin), named SIGN R1. Antigen Distribution: Isolated Cells: The antigen is found on a subpopulation of phagocytic macrophages isolated from the spleen and showing acid phosphatase and moderate non-specific esterase activity. These phagocytes selectively ingest neutral polysaccharides such as Ficoll. Tissue Sections: Subpopulation of resident macrophages in the splenic marginal zone which are in the proximity of a certain B cell subpopulation (μ+, d-). It is also found on a subpopulation of macrophages localized in the medullary sinuses and trabecular sinuses of lymph nodes. Furthermore, macrophage subpopulations in other organs, such as some connective tissue macrophages in the dermis, may also show ER-TR9 antigen expression.
Monoclonal antibody ER-TR9 is a very useful marker for the identification of macrophage subpopulations present in the marginal zone of spleen and lymph node medulla. ER-TR9 is also useful when studying phagocytosis of polysaccharides since the antibody selectively inhibits uptake of these glycans by macrophages.

CD209B also known as DC-SIGNR1 is a C-type lectin receptor with a molecular mass of about 45 kDa. This receptor is similar in structure to CD209A another member of the same gene family. CD209B is mainly expressed on macrophages and dendritic cells which are critical components of the immune system. This receptor plays a role in the immune response by recognizing and binding to specific carbohydrate structures on the surface of various pathogens.
Biological function summary
CD209B functions as part of a broader set of protein interactions involved in pathogen recognition and clearance. It acts as a pattern recognition receptor and is involved in initiating immune responses. Although not part of a large complex CD209B shares functional similarities with other receptors like CD209A mediating defensive strategies against infections through binding to glycoprotein antigens on microbes.
Pathways
The receptor participates in the immune signaling networks that oversee pathogen recognition. It is vital within the innate immune pathway where it helps to stimulate adaptive immunity. CD209B engages with proteins such as Toll-like receptors which amplify immune responses against pathogens.
CD209B has potential implications in infectious diseases and autoimmune disorders. Its ability to bind diverse pathogens makes it an important player in infections like HIV where it helps the virus gain entry into host cells. Additionally its interaction with proteins like mannose receptor suggests a role in diseases characterized by chronic inflammation. Understanding these interactions assists in developing interventions to modulate immune response in such conditions.
