Folate receptor 4 (FR4), also known as folate receptor delta or IZUMO1R, is a protein encoded by the FOLR4 gene in humans. It is a subtype of the receptor for the vitamin folic acid and is primarily expressed on CD4 T lymphocytes, with lower expression on CD8 T cells. FR4 is highly expressed in regulatory T cells (Tregs) and is also found in tumor-associated macrophages (TAMs) and T follicular helper cells (TFH cells). This protein plays a role in immune regulation, as its high expression can distinguish Tregs from other T cells. Additionally, FR4 is involved in the high-affinity binding and transport of folate and folate analogs across the cell membrane.
流式分析
Flow cytometric analysis of Mouse FR4 expression on BALB/c mouse splenocytes. BALB/c mouse splenocytes were stained with Brilliant Violet 421™ Rat Anti-Mouse CD4 Antibody and either Alexa Fluor® 488 Rat IgG1, κ Isotype Control (Left panel) or Alexa Fluor® 488 Rat Anti-Mouse FR4 Antibody (Right panel) at 1.25 μl/test. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.
