Fig. 7 — Molecular docking showing the interaction of microfilarial sheath antigen with phosphorylcholine. Crystal structure of phosphorylcholine was obtained from PubChem repository (PubChem ID: 135437). The 3D structure of microfilarial sheath antigen (FSAg) was obtained from our previously modelled structure¹³. The docking experiment was executed in silico employing Autodock Vina. Hydrogen bonds are depicted as yellow dashed lines. The conformation presented here possesses the negative binding energy (−4.0 kcal/mol)
