Mouse primary corneal epithelial cells (MPCEC)

… Each cornea was cut in half and placed in a 35 mm dish (Fisher Scientific, PA) with the epithelial side up. After approximately 5 minutes in the laminar air-flow culture hood, the half corneal button attached itself to the bottom of the plate, and 1.5 mL of DMEM (Life technology, NY) with 10% serum containing 40 μg/mL gentamicin (Life technologies, NY), 1% ITS (BD Biosciences, Bedford, MA), and 100 ng/mL cholera toxin (LIST Biological Laboratories, Inc., Campbell, CA) were added and the tissue was placed in a humidified incubator at 37 °C with 5% CO2. Culture medium was replaced every 2 days. After 7 to 10 days cells were nearly 100% confluent. …

Antigens:

… Recombinant protective antigen (rPA) was obtained from List Biological Laboratories (Campbell, CA). Each vial was reconstituted  

Quantification of anti-PA IgG antibodies:

Wells of an Immulon 2 HB, 96-well round bottom microtiter plate (Southern Biological, Birmingham, AL) were coated with 100 l of a coating solution (rPA diluted at 1 g/ml in a 0.01 M PBS solution, pH 7.4). …

Titration Curve:

Eight rPA-coated microtiter plates were prepared. Following overnight incubation, approximately 200 l of REF plasma that had been diluted to 1:500 was added to the first well of three rows on each plate then two-fold serial dilutions carried out. …

Specificity:

In the second experiment, two rPA coated microtiter plates were prepared, except that ovalbumin (100 l diluted at 1 g/ml in a 0.01 M PBS solution), a heterologous protein to B. anthracis PA, was also used to coat six wells in each plate. …

IL-27HA and IL-35HA gene therapy:

Chronic EAE was induced in female C57BL/6 mice by subcutaneous immunization with 300µl of 200µg per mouse of MOG3555 in Freunds Adjuvant Incomplete liquid, IFA, (Sigma) supplemented with 8mgml1 Mycobacterium tuberculosis (strain H37Ra; Difco, Lawrence, KS, USA). Pertussis toxin (500 ng, List Biological Laboratories, Campbell, CA, USA) was injected i.v. on the day of the immunization and again 2 days later. …

Mouse model of neonatal WMI:

Neonatal unilateral WMI was induced in C57BL/6 mice (Envigo) by inducing a hypoxic-ischemic insult, directly followed by an inflammatory stimulus, as adapted from Shen et al.^20,21. Briefly, at P5 HI+LPS mouse pups (n=6) underwent permanent occlusion of the right common carotid artery under isoflurane anesthesia, followed by exposure to 35minutes of hypoxia (6% oxygen). Immediately after hypoxia, pups received 1mg/kg LPS i.p. (List Biological Laboratories, Campbell, CA). …

Vaccination regimen with ovalbumin as antigen

Ovalbumine (OVA) is a commonly used antigen in order to assess adjuvant activity [19,32]. In two distinct assays, a total of fourteen mice per group received intra-rectally (IR) 20μg of ovalbumin (ovalbumin grade VII, Sigma) with 7μg of adjuvant, either cholera toxin (CT) (List Biological Laboratories, INC), …

Induction and evaluation of experimental autoimmune encephalomyelitis

Mice were 8 to 14 weeks of age at the time of immunization. Experimental autoimmune encephalomyelitis (EAE) was induced by subcutaneous immunization with 60 to 75 μg recombinant human myelin oligodendrocyte glycoprotein protein (rhMOG, AnaSpec) and 800 μg H37Ra (DIFCO Laboratories) emulsified in complete Freund’s adjuvant (DIFCO Laboratories) or 200 μl of recombinant human MOG1–125 Hooke-Kit (Hooke Laboratories) followed by two subsequent intraperitoneal injections of 300 ng pertussis toxin (List Biological Laboratories or Hooke Laboratories) at the time of immunization and respectively one or two days later. In some experiments 400 ng pertussis toxin was used, while taking care that controls and testing cohorts received the same amount. Boost was performed four to six weeks after immunization via a second subcutaneous injection with half the amount of the components from the primary EAE induction. Some mice were boosted with complete Freund’s adjuvant and Mycobacterium tuberculosis only. …
