Airway Allergic Responses Migration Inhibitory Factor Impairs Murine Cutting Edge: Deficiency of Macrophage

ISO-1, a macrophage migration inhibitory factor antagonist, inhibits airway remodeling in a murine model of chronic asthma.

Airway remodeling is the process of airway structural change that occurs in patients with asthma in response to persistent inflammation and leads to increasing disease severity. Drugs that decrease this persistent inflammation play a crucial role in managing asthma episodes. Mice sensitized (by intraperitoneal administration) and then challenged (by inhalation) with ovalbumin (OVA) develop an e...

Inhibitory Factor in Inhibiting NK Cell Activity Cutting Edge: Role of Macrophage Migration

Role of macrophage migration inhibitory factor (MIF) in allergic and endotoxin-induced airway inflammation in mice.

Macrophage migration inhibitory factor (MIF) has recently been forwarded as a critical regulator of inflammatory conditions, and it has been hypothesized that MIF may have a role in the pathogenesis of asthma and chronic obstructive pulmonary disease (COPD). Hence, we examined effects of MIF immunoneutralization on the development of allergen-induced eosinophilic inflammation as well as on lipo...

Cutting edge: STAT6 signaling in eosinophils is necessary for development of allergic airway inflammation.

Eosinophils are critical cellular mediators in allergic asthma and inflammation; however, the signals that regulate their functions are unclear. The transcription factor STAT6 regulates Th2 cytokine responses, acting downstream of IL-4 and IL-13. We showed previously that eosinophil-derived IL-13 plays an important role in the recruitment of T cells to the lung and the subsequent development of...

O-28: Endometriosis Is Influenced by The Promoter Haplotype-Based Expression of Macrophage Migration Inhibitory Factor (MIF)

Background: Macrophage migration inhibitory factor (MIF) is a key pro-inflammatory cytokine that is secreted by accumulated active macrophages in ectopic tissue of endometriosis. MIF is involved in pathophysiological events of endometriosis, such as angiogenesis and cell proliferation. MIF that stimulates the synthesis of PGE2, leads to over-expression of local estradiol synthesis in endometrio...
