Qiangke® is a dimeric, soluble fusion protein consisting of the extracellular ligand binding portion of the TNF receptor linked to the Fc portion of human Immunoglobulin gamma-1（IgG1）. It is capable of binding and neutralizing soluble TNF and transmembrane TNF. It alters neutrophil migration and dendritic cell and T-cell maturation and migration, thus decreasing the local and systemic production of pro-inflammatory cytokines and their subsequent effects.
