Differences in Wound Healing in Mice with Deficiency of IL-6 versus IL-6 Receptor

Deficiency of IL-6 versus IL-6 Receptor Differences in Wound Healing in Mice with

Essential involvement of IL-6 in the skin wound-healing process as evidenced by delayed wound healing in IL-6-deficient mice.

To clarify interleukin (IL)-6 roles in wound healing, we prepared skin excisions in wild-type (WT) and IL-6-deficient BALB/c [knockout (KO)] mice. In WT mice, the wound area was reduced to 50% of original size at 6 days after injury. Microscopically, leukocyte infiltration was evident at wound sites. Furthermore, the re-epithelialization rate was approximately 80% at 6 days after injury with in...

Serum soluble interleukin 6 (IL-6) receptor and IL-6/soluble IL-6 receptor complex in systemic juvenile rheumatoid arthritis.

By using a sandwich ELISA, soluble human IL-6 receptor (sIL-6 R) levels were measured in the sera of 20 healthy children and of 25 patients with systemic juvenile rheumatoid arthritis (JRA). In patients with systemic JRA, serum sIL-6 R levels (114.6 +/- 37.7 ng/ml) were significantly lower (P < 0.01) than those of healthy children (161.2 +/- 45.5 ng/ml). Serum sIL-6 R levels were negatively cor...

IL-6, IL-10 and IL-17 Gene Polymorphisms in Iranian Women with Recurrent Miscarriage

Background: Pro-inflammatory and anti-inflammatory cytokines and polymorphisms of their genes have been described to be involved in the pathogenesis of recurrent miscarriage (RM). Objective: To investigate the association between RM and five polymorphisms of cytokine genes, interleukin 10 (IL-10), (-592 A/C, -819 C/T, -1082 A/G), IL-6 (-174 C/G) and IL-17 (-197 G/A) in Iranian women. Method: Po...

Detection of IL-4, IL-6 and IL-12 Serum Levels in Generalized Aggressive Periodontitis

Background: Periodontitis is a multifactorial chronic inflammatory disease characterized by destruction of tooth-supporting tissues. Environmental and genetic factors as well as the immune system participate in this process. Recent studies have attempted to elucidate the role of cytokine networks involved in periodontal diseases. Objective: To assess and compare the levels of IL-4, IL-6 and IL-...
