Glomerular Disease Therapeutics Laboratory

More recently, we have developed rodent models to study common cold induced relapse of primary glomerular disease, and kidney and systemic effects of the COVID-19 cytokine storm. Novel therapeutic strategies include the use of recombinant mutated human Angiopoietin-like-4 to treat chronic kidney disease, sialic acid donors for sialylation based therapeutics, depletion of specific cytokines to prevent common cold induced relapse of Minimal Change Disease and Focal and Segmental Glomerulosclerosis, targeted cytokine depletion for acute treatment of COVID-19 related multi-system injury in rodent models, and modulation of ZHX2 expression for treating systemic dysfunctions in viral cytokine storms.


Research Unveils Paths to Stopping Cytokine Storms in COVID-19 (


Patented therapeutic strategies in accelerated development

  • The use of sialic acid based compounds in the treatment of human glomerular disease. U.S. patent has been issued, and PCT issued in some, and pending in other jurisdictions.
  • The use of recombinant human Angiopoietin-like-4 and its mutants in the treatment of Chronic Kidney Disease associated with proteinuria. Two patent families have been issued in multiple jurisdictions.
  • Targeted cytokine depletion to prevent relapse of nephrotic syndrome triggered by a common cold. PCT/US2019/042748.
  • Methods of treating the effects of cytokine storms. PCT/US22/47254.
  • Methods of improving systemic disease outcomes by inhibition of ZHX2. PCT/US22/47263.
