Abstract:
Understanding the modulation of the host‐immune system by pathogens‐like filarial parasites offers an alternate approach to prevent autoimmune diseases. In this study, we have shown that treatment with filarial proteins prior to or after the clinical onset of streptozotocin‐induced type‐1 diabetes (T1D) can ameliorate the severity of disease in BALB /c mice. Pre‐treatment with B rugia malayi adult soluble (Bm A S) or microfilarial excretory‐secretory ( Bm mf ES) or microfilarial soluble ( Bm mf S) antigens followed by induction of diabetes led to lowering of fasting blood glucose levels with as many as 57·5–62·5% of mice remaining nondiabetic. These proteins were more effective when they were used to treat the mice with established T1D as 62·5–71·5% of the mice turned to be nondiabetic. Histopathological examination of pancreas of treated mice showed minor inflammatory changes in pancreatic islet cell architecture. The therapeutic effect was found to be associated with the decreased production of cytokines TNF ‐α & IFN ‐γ and increased production of IL ‐10 in the culture supernatants of splenocytes of treated mice. A switch in the production of anti‐insulin antibodies from IgG2a to IgG1 isotype was also seen. Together these results provide a proof towards utilizing the filarial derived proteins as novel anti‐diabetic therapeutics.
