Induction of EAE

Active EAE was induced following previously published procedures [23]. In brief, 8–10-week-old female C57BL/6J mice (#000664, The Jackson Laboratory) were injected subcutaneously in both flanks with a total of 100 μg of MOG35-55 peptide (EZBiolab) in complete Freund’s adjuvant (CFA) containing 4 mg/mL Mycobacterium tuberculosis (DIFCO Laboratories). Mice also received 400 ng of pertussis toxin (LIST Biological Laboratories) intraperitoneally both immediately after immunization and 48 h later. Control, mock-injected mice were injected with everything except the MOG peptide. …

Induction of experimental autoimmune orchitis (EAO)

Age-matched male Gsdmdfl/flCx3cr1-cre and Cx3cr1-cre mice were used to induce EAO, as described previously (Nicolas et al, 2017). First, the testicular homogenate (TH) was obtained from decapsulated testes of adult syngeneic mice and homogenized in an equal volume of sterile PBS. Second, TH was mixed with incomplete Freund’s adjuvant (IFA; Sigma-Aldrich, F5506) containing 1 mg/ml Mycobacterium tuberculosis (BD, 231141) in 1:1 ratio. Finally, the mice were immunized thrice every 14 days with the mixture, followed by an intraperitoneal injection of 100 ng pertussis toxin (List Biological Laboratories, lot#180) in 100 μl PBS. Each animal was immunized dorsally at four sites near the popliteal lymph nodes in a total volume of 200 μl. The testes were collected for further analysis 50 days after the first immunization.
