Establishment of Monoclonal Antibody PMab-202 Against Horse Podoplanin.
Abstract: Podoplanin (PDPN), a type I transmembrane glycoprotein, is expressed in several body tissues, including podocytes of renal glomerulus, type I alveolar cells of lung, and lymphatic endothelial cells. PDPN activates platelet aggregation by binding to C-type lectin-like receptor-2 (CLEC-2) presented on platelets. Monoclonal antibodies (mAbs) against human-, mouse-, rat-, rabbit-, dog-, bovine-, and cat-PDPN have already been established. However, anti-horse PDPN mAbs have not yet been developed. In this study, we immunized mice with synthetic horse PDPN peptides and developed anti-horse PDPN mAbs. One of the established mAbs, PMab-202 (IgG, kappa), was specifically able to detect horse PDPN in Chinese hamster ovary/horse PDPN (CHO/horPDPN) cells in flow cytometry experiments. PMab-202 was also able to detect endogenous horse PDPN expressed in and a horse kidney cell line, FHK-Tcl3.1, in flow cytometry and Western blot analyses. PMab-202 is expected to prove useful in investigating the function of horse PDPN.

This research outlines the development of a specific monoclonal antibody, PMab-202, designed to detect horse podoplanin, a protein important for platelet aggregation, which had not been created prior to this study.
Background on Podoplanin and Monoclonal Antibodies
- Podoplanin (PDPN) is a type 1 transmembrane glycoprotein expressed in various bodily tissues, such as renal glomerulus podocytes, lung’s type I alveolar cells, and lymphatic endothelial cells. It plays a crucial role in activating platelet aggregation by binding to the C-type lectin-like receptor-2 (CLEC-2) found on platelets.
- Monoclonal antibodies (mAbs) are a type of antibody made by identical immune cells, clones of a unique parent cell, designed to target a specific protein.
- Despite the development of monoclonal antibodies against PDPN in various species such as humans, mice, rats, rabbits, dogs, cows, and cats, none had been created specifically to target PDPN in horses before this study.
Purpose and Methodology of the Study
- The aim of this research was to develop an antibody that could specifically detect horse PDPN.
- The researchers accomplished this by immunizing mice with synthetic horse PDPN peptides, leading to the development of antibodies against horse PDPN.
Results of PMab-202 Development
- One of the resultant monoclonal antibodies, PMab-202, displayed the ability to specifically detect horse PDPN in particular cell types, as demonstrated by flow cytometry experiments.
- PMab-202 effectively detected endogenous horse PDPN expressed in and a horse kidney cell line, FHK-Tcl3.1, when evaluated through flow cytometry and Western blot analyses.
Future Implications of the Research
- PMab-202 is anticipated to be a valuable tool for studying the function of horse PDPN, widening the potential for more comprehensive research into the role of this protein in horses.
- This developed antibody also paves the way for further research looking at potential veterinary applications, particularly in the context of diseases or conditions where PDPN is implicated.
