The measurement technologies of thyrotropin receptor antibodies from the past to the present
Thyroid Stimulating Hormone Receptor (TSH-R) autoantibodies are the main cause of Graveschr('39') disease and its external thyroid manifestations such as ophtalmopathy and dermatopathy. These antibodies are functionally different and are commonly called TSH receptor antibodies (TRAbs). In fact, TRAbs are a set of autoantibodies including TSHR-stimulating antibodies (TSAbs), TSHR- blocking antib...
متن کاملLigand Binding Sites of Inducible Costimulator and High Avidity Mutants with Improved Function
Interaction between inducible costimulator (ICOS) and its ligand is implicated in the induction of cell-mediated and humoral immune responses. However, the molecular details of this interaction are unknown. We report here a mutagenesis analysis of residues in ICOS that are critical for ligand binding. A three-dimensional model of the extracellular immunoglobulin-like domain of ICOS was used to ...
متن کاملMolecular Dynamics Simulation and Free Energy Studies on the Interaction of Salicylic Acid with Human Serum Albumin (HSA)
Human serum albumin (HSA) is the most abundant protein in the blood plasma. Molecular dynamics simulations of subdomain IIA of HSA and its complex with salicylic acid (SAL) were performed to investigate structural changes induced by the ligand binding. To estimate the binding affinity of SAL molecule to subdomains IB and IIA in HSA protein, binding free energies were calculated using the Molecu...
متن کاملIn-silico Investigation of Tubulin Binding Modes of a Series of Novel Antiproliferative Spiroisoxazoline Compounds Using Docking Studies
Interference with microtubule polymerization results in cell cycle arrest leading to cell death. Colchicine is a well-known microtubule polymerization inhibitor which does so by binding to a specific site on tubulin. A set of 3',4'-bis (substituted phenyl)-4'H-spiro[indene-2,5'-isoxazol]-1(3H)-one derivatives with known antiproliferative activities were evaluated for their tubulin binding modes...
