We sequenced in 1981 a protein with unknown function, now called cystatin C, which defined a new superfamily of cysteine protease inhibitors ("cystatins"). We have described several new cystatins and shown that cystatin C is produced by a house-keeping gene and that a mutation in it causes the dominantly inherited disease "Hereditary Cystatin C Amyloid Angiopathy" in which L68Q-cystatin C is precipitated as amyloid in affected individuals, who die from brain hemorrhage before 40 years of age. We have demonstrated that cystatin C amyloid deposits may form by "propagated domain-swapping" and shown that inhibition of domain swapping prevents the in vitro formation of cystatin C amyloid. We have also demonstrated that cystatin C modulates the amyloid deposits in Alzheimer disease. We have demonstrated that certain peptidyl derivatives based upon the structure of cystatin C will kill grampositive bacteria resistant to all known presently available antibiotic compounds and some viruses. We demonstrated in 1984 that the serum level of cystatin C probably is a better marker for glomerular filtration rate than creatinine. We produced an international calibrator for cystatin C in 2010.

We will produce low molecular mass compounds preventing domain swapping of cystatin C by a molecular dynamics approach and by high-throughput screening of drug libraries. 
We will, in addition, try to elucidate the antibacterial and antiviral mechanisms of cystatin-based antibacterial and antiviral compounds in an effort to create a new class of clinically useful antibacterial substances.
We will try to identify those clinical situations in which serum cystatin C will be a particularly important marker for specific renal dysfunction in an effort to substitute non-invasive for invasive diagnostic procedures for kidney disease. We will produce an assay-independent cystatin C-based GFR prediction equation.

Development of drugs against amyloid disorders and multiresistant bacteria may allow treatment of presently incurable disease states. Improved GFR-prediction equations will allow better evaluation of renal disease and safer dosing of drugs and contrast media excreted via the kidneys.
