Signaling through the PGI(2) receptor (IP) has been shown to inhibit inflammatory responses in mouse models of respiratory syncytial viral infection and OVA-induced allergic responses. However, little is known about the cell types that mediate the anti-inflammatory function of PGI(2.) In this study, we determined that PGI(2) analogs modulate dendritic cell(More)
IL-17A is produced from Th17 cells, and is involved in many autoimmune and inflammatory diseases. IL-13R has not previously been reported to be functionally expressed on T cells; however, we found that purified BALB/c CD4(+) cells polarized to Th17 with TGF-beta, IL-6, and IL-23 have increased mRNA and protein expression of IL-13R alpha1 and mRNA expression(More)
Respiratory syncytial virus (RSV) is associated with wheezing and childhood asthma. We previously reported that RSV infection prolongs methacholine-induced airway hyperresponsiveness in ovalbumin (OVA)-sensitized mice. In addition, allergically sensitized RSV-infected (OVA/RSV) mice had more abundant airway epithelial mucus production compared with OVA mice(More)
In this paper, input-to-state stability problems for a class of recurrent neural networks model with multiple time-varying delays are concerned with. By utilizing the Lyapunov–Krasovskii functional method and linear matrix inequalities techniques, some sufficient conditions ensuring the exponential input-to-state stability of delayed network systems are(More)
Complement C3 produced within the kidney may be an important mediator of local inflammatory and immunological injury. The overall level of renal C3 production and consequently its contribution to the total circulating C3 level are, however, unknown. This was investigated by using the conversion of C3 from recipient to donor allotype following renal(More)
The role of prostanoids in modulating respiratory syncytial virus (RSV) infection is unknown. We found that RSV infection in mice increases production of prostaglandin I(2) (PGI(2)). Mice that overexpress PGI(2) synthase selectively in bronchial epithelium are protected against RSV-induced weight loss and have decreased peak viral replication and gamma(More)
The mechanisms by which chronic inflammatory lung diseases, particularly chronic obstructive pulmonary disease, confer enhanced risk for lung cancer are not well-defined. To investigate whether nuclear factor (NF)-κB, a key mediator of immune and inflammatory responses, provides an interface between persistent lung inflammation and carcinogenesis, we(More)
BACKGROUND Viral infections are the most frequent cause of asthma exacerbations and are linked to increased airway reactivity (AR) and inflammation. Mice infected with respiratory syncytial virus (RSV) during ovalbumin (OVA)-induced allergic airway inflammation (OVA/RSV) had increased AR compared with OVA or RSV mice alone. Furthermore, interleukin 17A(More)
Nonselective cyclooxygenase (COX) inhibition during the development of allergic disease in a murine model causes an increase in type 2 cytokines and lung eosinophilia; however, the mechanisms responsible for this augmented allergen-induced inflammation have not been examined. Ab depletion of CD4 and CD8 cells revealed that the heightened allergic(More)
Th cell differentiation from naive precursors is a tightly controlled process; the most critical differentiation factor is the action of the driving cytokine: IL-12 for Th1 development, IL-4 for Th2 development. We found that CD4(+) T cells from nonobese diabetic mice spontaneously differentiate into IFN-gamma-producing Th1 cells in response to polyclonal(More)
