Background: IL-4 is a cytokine that induces differentiation of naive helper T cells into Th2 cells. Once activated by IL-4, Th2 cells subsequently produce additional IL-4. Objective: To examine the effect of IL-4 on IL-17 production and its effect in Collagen- Induced Arthritis (CIA) mice. Method: In this study, a chicken collagen-II-induced experimental arthritis (CIA) model was used in DBA/1 ...

background: cesarean section delivery can lead to much maternal morbidity. different cytokines have been reported to be influenced by the mode of delivery. objective: to investigate the influence of mode of delivery on maternal, placental and cord sera of interferon gamma (ifn-γ), interleukin-4 (il-4) and interleukin-10 (il-10) levels. methods: these three cytokines were measured using elisa in...

immune and inflammatory responses mediated by cytokines, play important roles in the pathophysiology of asthma. these responses are associated with overexpression of th2 cytokines such as il-4 and il-13. these two cytokines use common receptors for signaling that lead to identical immunological effects and regulation of the th1/th2 balance. the aim of this study was to determine whether patient...

chronic lymphocytic leukemia (cll) remains an incurable disease that requires innovative new approaches to improve therapeutic outcome. many ferula species, including f. asa-foetida, synthesize terpenyloxy coumarins. one of these coumarins is umbelliprenin, which has been implicated with induction of apoptosis in some cancer cell lines.     in this study induction of apoptosis by umbelliprenin ...

background: current treatments for joint diseases are moderately successful, but unfortunately are associated with significant side effects. this study was undertaken to investigate the combination effects of il-4 and prednisolone on tissue characteristics and production of matrix metalloproteinase-1(mmp-1) in il-lα-treated bovine nasal cartilage (bnc) explants. methods: bnc explants were cultu...
