Buy FGL2 (Fibroleukin) 1mg

FGL2 (Fibroleukin) is a member of the fibrinogen superfamily that functions as an immune checkpoint molecule. It is secreted by regulatory T cells (Tregs) and exerts immunosuppressive effects through FcγRIIB receptor signaling, inhibiting dendritic cell maturation and effector T cell activation. FGL2 represents a novel approach to modulating the immune system for autoimmune and chronic inflammatory conditions.

▸Regulatory T Cell Axis

FGL2 is part of the Treg suppression arsenal — the molecular tools that regulatory T cells use to dampen immune overactivity. By expanding Treg function and inhibiting pro-inflammatory dendritic cell activation, FGL2 creates a more tolerogenic immune environment without global immunosuppression.

▸Research Applications

FGL2 has been studied in models of transplant tolerance, autoimmune hepatitis, inflammatory bowel disease, and sepsis-related immunopathology. Its mechanism differs fundamentally from anti-inflammatory peptides like BPC-157 — where BPC-157 reduces local inflammation through growth factor modulation, FGL2 acts centrally on the adaptive immune regulatory network.

▸Advanced Research Compound

FGL2 is a frontier immune research compound with significant mechanistic interest but limited clinical data. It is typically used by advanced researchers exploring immune modulation protocols, often in combination with more established anti-inflammatory peptides.
