Diphtheria toxin-induced monocyte depletion mouse model:

Itgam(CD11b)-DTR mice were obtained from Jackson Laboratories. CD11b-DTR and C57BL/6 WT mice were injected i.p. with 100 l of diphtheria toxin (List Biological Laboratories, Inc. Campbell, CA) at a concentration of 0.02 g per gram of mouse weight. Two days after PBS or CpGB DNA pump insertion, skin was collected for RNA isolation or immunofluorescence.

RESULTS – Multiple TLR ligands and cytokines stimulate HC-TNFR1 shedding during polymicrobial sepsis:

We previously showed that HC-TNFR1 shedding is stimulated by the TLR4 ligand lipopolysaccharide (LPS) in vitro and in vivo (10); however, during polymicrobial sepsis, multiple TLR ligands and cytokines are involved in propagating the inflammatory response. …

Induction and evaluation of EAE:

To induce relapse EAE, SJL.J mice were immunized with 150µg of PLP₁₃₉₁₅₁ in CFA containing 5mg/ml¹ heat-killed Mycobacterium tuberculosis. For both types of induction, on the day of immunization and 48h later, the mice were also injected i.v. with Pertussis toxin (200ng per mouse; List Biological Laboratories, Campbell, CA) in PBS. Mice were examined daily for EAE disease symptoms, which were scored using a…
