Treatment of reproductive tract cells with PAMP:

To determine whether PAMP affected antigen presentation by uterine and vaginal cells, PAMP were added to individual wells in antigen presentation assays at the start of each experiment. To measure the effect of PAMP on co-stimulatory molecule expression, PAMP were added to epithelial cells, stromal cells and vaginal cells (5 10⁵ cells/100 ml) at the start of each 24 hr incubation period as previously described.^28,44 The TLR agonists used in these studies included TLR1/TLR2: Pam₃Cys-Ser-(Lys)4 (P3C, EMC Microcollections, Tbingen, Germany) at a final concentration of 10 g/ml; TLR2/TLR6: Peptidoglycan from Staphylococcus aureus (InvivoGen), 10 g/ml; TLR3: Poly(I:C) (InvivoGen), 25 g/ml; TLR4: ultra-pure lipopolysaccharide from Salmonella minnesota (LPS; List Biological Laboratories, Inc., Campell, CA), … Wells containing media alone were included in all experiments as controls. The TLR agonists were tested for LPS contamination using the Limulus assay …

Spinal Application of Pertussis Toxin and Cholera Toxin:

Bacterial toxins, pertussis toxin (PTX) and/or cholera toxin (CTX) (List Biological Laboratories Inc., Campbell, CA, for both), were injected via the intrathecal cannula to block Gi/Go and Gs proteins, respectively. PTX (10 µg/5 µl) was injected every other day (days 1, 3, and 5) during the last 5 days before sacrifice. CTX (5 µg/5 µl) was injected once 24 h before sacrifice.
