  • Autoimmune workup was negative. Workup for other causes of nodular glomerulosclerosis such as amyloidosis, LCDD, and immune deposition diseases was negative.[ncbi.nlm.nih.gov]
Lymphocytic Infiltrate
  • In one cat, an islet showed a dense lymphocytic infiltration. — No lesions identical to human diabetic glomerulosclerosis were found in any of the dogs or cats.[glosbe.com]
  • Vessels and tubulointerstitium were unremarkable except for focal lymphocytic infiltrates. Immunofluorescence was negative for IgM, IgA, IgG, C3C, C1q, k, and λ.[ncbi.nlm.nih.gov]


  • And the FDA has not approved any drugs specifically for its treatment. But several treatments can slow its progression and control symptoms.[webmd.com]
  • TGFβ treatment of podocytes does not alter cell morphology but increases connective tissue growth factor (CTGF) expression.[ncbi.nlm.nih.gov]
  • Short-term IL-33 treatment in mice led to sustained expansion of IL-33 receptor-positive kidney ILC2s and ameliorated adriamycin-induced glomerulosclerosis.[ncbi.nlm.nih.gov]
