Stereotactic surgery (6-OHDA infusion and BoNT-A Injection):

… 6-OHDA infused and control rats then received BoNT-A injection (List Biological Laboratories, Campbell, California, USA) at the right EPN four weeks after 6-OHDA surgery. Delivery of 0.5 ng of BoNT-A into the EPN was performed by injection of 0.5 uL of BoNT-A solution (0.5 L of 1 ng/uL BoNT-A dissolved in phosphate buffered saline (PBS) containing 0.1% bovine serum albumin (BSA)). Infusions were performed over 5 minutes via a 31G injection cannula attached to a 10 uL Hamilton syringe. Correspondingly, vehicle animal groups were administered with an equivalent volume of PBS with 0.1% BSA. The stereotactic coordinates with reference to bregma were: AP -2.5 mm, L 3 mm, DV 7.7 mm (Paxinos and Watson, 2009).

EAE immunization:

… EAE was induced by subcutaneous injection of 300g of myelin oligodendrocyte glycoprotein peptide (MOG3555; KJ Ross-Petersen ApS, Copenhagen, Denmark) emulsified with complete Freund’s adjuvant (CFA; Sigma, USA) in both hind flanks of each mouse. All mice received an intraperitoneal (i.p.) injection of 0.3µg pertussis toxin (List Biological Lab, USA) immediately and 48h after immunization. …

Macrophage isolation and polarization:

Using aseptic technique, femurs were harvested, and the bone marrow flushed from C57BL/6 and Tmem173^gt mice for macrophage polarization studies. The BMDMs were expanded in culture for 7 d in the presence of L-929 mouse fibroblast conditioned medium as a source of M-CSF. Cells were re-seeded onto 6-well plates at 210⁶ cells/well and polarized for 48 hrs with the addition of 50ng/ml LPS (List Biological Labs) and 50ng/ml murine IFN (Cedarlane) for M1, 40ng/ml murine IL-4 (R&D Systems) for M2 or left untreated for M0 cells. …
